Tsakalis AudioWorks Room #40
tskalisaudioworks.com
Like a lot of amp-in-a-box pedals, the Room #40 from Tsakalis AudioWorks makes some pretty lofty claims. Specifically, it alleges to capture the soul and essence of a Marshall plexi and, with the flip of a switch, a JCM800, too. There’s a lot of reasons to try to replicate the sound and feel of these amps in a pedal—not least their resale values of late. I’ve played a slew of Marshall-in-a-box pedals. And while many of them deliver convincing-enough bark, they’re rarely dynamic enough to stay on my pedalboard for long. The Room #40, however, often escapes that trap and offers a lot of flexibility for matching it to changing backlines.
Jump(ered)!
While the Room #40 has more knobs than either of the amplifiers it seeks to imitate, the extra controls make the pedal more flexible and dynamic. The four larger gold dials are the meat-and-potatoes. In plexi mode (toggle up), they offer a control scheme like on the “jumpered” inputs of a plexi. Vol I acts like the treble channel and Vol II works like the normal channel. In JMP/JCM800 mode (toggle down), Vol 1 is preamp volume and Vol II adjusts the low end. Once you’ve found your desired blend, the master sets the overall output. The fourth gold knob controls the “variac” function. EVH freaks, of course, know where this is going. During Eddie’s early career, he used a Variac transformer to step down the voltage of his Marshall and craft his fabled “brown sound.” Tweaking this knob on the Room #40 has a similar effect, altering the voltage between 7.5V to 21.5V to recast the compression and attack.
The 3-band EQ along with the essential presence control helps shape high-end frequencies. The final embellishment is a dedicated boost footswitch which kicks up the gain and accentuates the mids. It’s adjustable on the back of the pedal with a screwdriver, so there’s no need to take off the backplate.
Riding the Night Train
With the Room #40 plugged into a ’60s Fender Bassman and a Gibson Les Paul, engaging the effect lends the distinctly American side of the Bassman (an amp that can sound quite Marshall-y at volume) a very British overdrive accent. Sounds from the plexi mode are robust and surprisingly complex. And plenty of bottom-end is available by cranking up Vol II. If you’ve never played a jumpered Marshall, the Room #40’s controls can take getting used to. I’d suggest leaving the EQ flat until you find the right gain profile. I tend to keep my Bassman’s bright switch engaged for a little more punch. But it wasn’t as critical with the Room #40 in the mix, and high-end frequencies I needed to add or subtract were easily handled with the #40’s presence and high-frequency controls.
“Sounds from the plexi mode are robust and surprisingly complex.”
Switching over to an Orange OR50 and a Fender Stratocaster, the Marshall flavor came through clearest and sounded most complex at lower gain settings. You can definitely hit a dirty amplifier like the Orange with the Room #40, but the crunchier OR50 clearly overshadowed some of the Room #40’s charm and capacity for detail. Yet even with less headroom, the EQ and variac provide a lot of flexibility, and the boost is an excellent means for cutting through the dirt a bit. When running with dirtier amp settings, I liked the JMP/JCM mode with a little less Vol 1 output, which makes the Room #40 function more like a glassy, sparkly lead boost, rather than just dumping more gain into the signal path. However, maxing the Vol 1 control in this context delivers tons of grindy chug, and you can use the variac to shape a punchier response. In the upper regions of the variac sweep you get more headroom and loads of that no-nonsense attack you expect from a Marshall. But it also bears mentioning that the compression from the Room#40 feels properly spongy and authentic at the right settings.
The Verdict
For the gigging musician that needs Marshall flavor for a mystery backline or a less Marshall-like tube amp, the Room #40 is a cool way to get there. It’s compact, the tones are impressive, and it will cooperate with nearly any amp thanks to a versatile EQ and presence control. If that’s not enough, the variac knob and boost features further help set this pedal apart and make the $245 price seem pretty fair.

Featuring vintage tremolos, modern slicer effects, and stereo auto-panners, the update includes clever Rate and Tempo controls for seamless syncing and morphing.
Today Kemper announces the immediate availability PROFILER OS 12.0 including the highly anticipated collection of advanced Tremolo and Slicer FX for the entire range of KEMPER PROFILER guitar amps.
The Collection features three vintage tremolos, two modern slicer effects, and two stereo auto-panners, that have been derived from the slicer effects. They all feature a clever Rate and Tempo control system, that allows for syncing the tremolo to the song tempo, retriggering the timing by simply hitting the TAP switch, and changing or morphing the tremolo rate to different note values,
The new Advanced Tremolo Modules in Detail
- The Tube Bias Tremolo is the familiar Tremolo in the Kemper Profilers. Formally named "Tremolo“ and available in the PROFILERs since day one, it is a reproduction of the famous Fender Amp tremolos from the 50‘s. Placed in front of the amp it beautifully interacts with the amp distortion.
- The Photocell Tremolo dates back to the 60‘s and features a steeper pulse slope, and its width varies with the intensity.
- The Harmonic Tremolo also dates back to the 60‘s and was introduced by Fender. The low and high frequencies alternate with the tremolo rate.
- The Pulse Slicer is a modern slizer or stutter effect that will continuously transition from the smoothest sine wave to the sharpest square wave, using the "Edge“ parameter. The "Skew“ parameter changes the timing of the high level versus the low level, sometimes also called pulse width or duty cycle.
- The Saw Slicer creates a ramp like a saw wave. The saw wave has a falling ramp when "Edge“ is at full position, and a rising edge at zero position. Towards the middle position a rising and falling ramp are forming a triangle wave. The „Skew“ parameter changes the slope of the rising and falling ramp from a linear trajectory to a more convex or concave shape.
- The Pulse Autopanner and the Saw Autopanner are derivates from their respective Slicers, they spread their signals in the stereo panorama. The "Stereo“-control parameter is included in many effects of the PROFILER. Here, it introduces a novel "super-stereo" effect that lets the Autopanner send the signal well outside the regular stereo image. This effect works best if you are well positioned in the correct stereo triangle of your speakers. When you move the “Stereo” soft knob beyond the +/-100% setting, the super-stereo effect comes into place, reaching its maximum impact at +/-200%.
- A single press on the TAP button at the beginning of the bar will bring the rhythmic modulation effects, such as Tremolo or Slicer, back into sync with the music without changing the tempo. The sync will happen smoothly and almost unnoticeable, which is a unique feature. Of course, tapping the tempo is possible as well.
- Modulation Rate - The “Rate” control available in many modulation effects is based on a special philosophy that allows continuous control over the speed of the modulation and continuous Morphing, even when linked to the current tempo via the To Tempo option. The fine Rate resolution shines when seamlessly morphing from, e.g., 1/8 notes to 1/16 notes or triplets without a glitch and without losing the timing of the music.
The Georgia-based sludge slingers rely on a Tele-to-Marshall combination for their punishing performances.
Since forming in 2010, Atlanta noise rockers Whores had only released one LP, 2016’s Gold.—until this year. Eight long years later, their new full-length, WAR., dropped in April, and Whores celebrated by tearing across the country and blasting audiences with their maelstrom of massive, sledge-hammering rock ’n’ roll.
The day after their gig at Cobra Nashville, Whores frontman Christian Lembach, dressed in his Nashville best, met up with PG’s Chris Kies at Eastside Music Supply to run through his brutal road rig.
Brought to you by D’Addario.Earthy Esquire
When vocalist and guitarist Christian Lembach got sober over 20 years ago, he bought a Fender Telecaster off of a friend, then picked up an Esquire shortly after. That original Esquire stays home, but he brings this pine-body Earth Guitars Esquire out on the road. (It’s the lightest he’s ever played.) It’s loaded with a German-made reproduction of Schecter’s F520T pickup—aka the “Walk of Life” pickup intended to reproduce Mark Knopfler’s sound. (Lembach buys them in batches of five at a time to make sure he’s got plenty of backups.)
It’s equipped with a 3-way selector switch. At right, it bypasses the tone circuit; in the middle position, it’s a regular bridge-pickup configuration, with volume and tone activated; and at left, the tone is bypassed again, but an extra capacitor adds a bass boost.
Lembach installed six brass saddles in lieu of the traditional 3-saddle bridge. He often plays barre chords higher up the neck, and the six saddles allow for more accurate intonation.
All of Lembach’s guitars are tuned to drop C, and he plays with D’Addario Duralin .70 mm picks. They’re strung with heavy D’Addario NYXL sets, .013–.056 with a wound G. The 30-foot Bullet Cable coil cable attenuates some of the guitar’s top end.
Tuned-Up Tele
Lembach had this black Fender Telecaster—the one he bought from his friend—modified to his preferred Esquire specs, with a single bridge pickup and the same 3-way selector configuration as his other weapon. He prefers the 6-saddle bridge to this rusty 3-saddle version, but this one holds a special place in his heart all the same.
Favor From Furlan
When John Furlan of Furlan Guitars reached out to Lembach about building him a custom guitar, it was an easy sell. The two worked together on this beauty, based on a non-reverse Gibson Firebird body with a Fender-style scale length, roasted maple neck, and rosewood fretboard.
It’s got a bridge and locking tuners from Hipshot, and it’s loaded with Greenville Beauty Parlor P-90s. A typical Gibson-style toggle switches between neck, bridge, and both configurations, while another Esquire-style 3-way switch on the lower bout handles Lembach’s preferred bridge-pickup wirings: no tone, tone and volume, or bass boost.
No Logo
Lembach stays loyal to his twin Marshall Super Leads, with taped-over logos—an aesthetic Lembach picked up from Nirvana. A tech in Atlanta figured out that the one on the left is a 1973, which runs at eight ohms, or half power (Lembach removed two of the power tubes), into a 16-ohm cabinet. The power drop allows Lembach to coax feedback at lower volumes. The original preamp tubes from Yugoslavia—no longer a country, mind you—are still working in the amp.
The one on the right is a reissue 1959SLP from 2002 or 2003, which Lembach finds brighter than his vintage model. He goes into the lower-input second channel to dampen the edge.
Both amps run through Marshall JCM800 cabinets with Celestion G12T-75s.
Christian Lembach's Board
A Loop-Master Pedals Clean/Dirty Effects Switcher manages Lembach’s signal. Its A loop is used for verses, bridges, intros, and outros, and has the majority of the pedals in it. The first thing in the A loop is the ZVEX Fuzz Factory made specially for the band, followed by a Devi Ever Soda Meiser, Beetronics Swarm, Keeley Nova Wah, Spiral Electric FX Yellow Spiral, Boss NF-1, and Alexander Pedals Radical II Delay.
The B loop has a clone of the Electro-Harmonix Green Russian Big Muff, an EHX POG, and a ZVEX Super Hard On. The A loop is already pretty loud; B somehow gets even louder. An EHX Superego+ is a new addition that Lembach’s planning to integrate.
A CIOKS DC10 powers the board, and a Lehle device under the board cleans up unwanted hum and noise.
“Get It Right, Get It Fast”: Jerry Douglas on Bluegrass History and Session Secrets
The legendary Dobro player talks about how to get session work, working with Allison Kraus, and the “baton pass” involved in recording great songs.
Bluegrass music is bigger than a genre. It’s become an entire world of ideas and feelings in the popular American imagination. And musician Jerry Douglas has been a key part of its celebration and revival over the past 30 years. “It's an old form of music that came from people in the south playing on the porch and became this juggernaut of a genre,” says Douglas. “It’s a character. It's a physical music.”
Douglas has racked up an impressive cabinet of accolades, including Grammys, American Music Association Awards, and International Bluegrass Music Association Awards. He’s been dubbed the CMA Awards’ Musician of the Year three times, and played with everyone from Allison Krauss and Elvis Costello to Bela Fleck and John Fogerty. He’s an encyclopedic guide to contemporary American roots music, and on this episode of Wong Notes, he walks Cory Wong through the most important moments in his 50-year career.
Tune in to hear Douglas’ assessment of bluegrass’ demanding nature (“Honestly, there's not so many genres nowadays that require as much technical facility as something like bluegrass”), what’s required of roots players (“Get it right, get it fast, make it hook”), and why the O Brother, Where Are Thou? soundtrack connected with so many listeners. Wondering how to get involved with session work? Douglas says there’s no one-size-fits-all answer, and what worked for him might not work today. The key is to be dynamic—and know when to keep your mouth shut.
There are plenty of gems in this interview, like Douglas’ thoughts on what makes a good solo, but the most significant might be Douglas’ big takeaway from decades of sitting in on communal roots-music sessions. “We can play in all genres,” says Douglas. “We just have to listen.”
The perennial appeal of one of Gibson’s most accessible Les Pauls is stoked anew in this feature-rich version.
Lots of nice vintage touches and features that evoke the upmarket Les Paul Standard at a fraction of the price. Coil-splitting capability.
A thicker neck profile would be a cool option and distinguishing feature.

Gibson Les Paul Studio
gibson.com
Effectively a no-frills version of theLes Paul Standard, the Les Paul Studio has been a fixture of Gibson product rosters since 1983, which says something about the enduring, and robust, appeal for affordable alternatives to the iconic original. The notion behind the original Les Paul Studio was that it didn’t matter how a guitar looked when you were using it in the studio. Who cares about a flamed top, binding, inlays, and other deluxe cosmetics in a session as long as it sounds and feels good?
In some respects, the newestLes Paul Studio adheres to that philosophy and shares many trademark elements with its Studio forebears. There’s no body binding and a silkscreened, rather than inlaid mother-of-pearl headstock logo, for instance. But Gibson also carefully and cleverly threaded the needle between economy and luxury with this release, including several desirable Les Paul features that have occasionally been excluded from the budget model over the years.
Classic Contours
Most readers with a cursory knowledge of the Les Paul format will know this guitar’s basic specs already: mahogany body with maple top, mahogany set neck, 24.75" scale length, 12" fingerboard radius, and dual humbuckers. The Les Paul Studio hasn’t always followed the Standard’s, um, standard quite so religiously. Studios from the first few years of the model’s existence, for example, were made with alder bodies and slightly thinner than the usual Les Paul depth. The newest version, too, veers from formula a bit by using Gibson’s Ultra Modern weight relief scheme, which slims the guitar’s weight to about 8 1/2 pounds. The carved maple top, however, is plain and not heavily figured, which keeps costs down. Even so, it looks good under the bright-red gloss nitrocellulose lacquer finish on our cherry sunburst example. (Wine red, ebony, and the striking blueberry burst are also available).
While the binding-free body and less-heavily figured top hint at the Studio’s “affordable” status, Gibson didn’t skimp on dressing up the neck. It has a bound rosewood fretboard with trapezoidal pearloid inlays rather than the dots many early versions featured. For many players, though, the fretboard binding is more than cosmetic—the ever-so-slight extra width also lends a more vintage-like feel, so it’s really nice to have it here. The neck itself is carved to Gibson’s familiar and ubiquitous Slim Taper profile, a shape inspired by early-’60s necks that were generally thinner and flatter than the ’50s profiles.
“Gibson carefully and cleverly threaded the needle between economy and luxury with this release.”
Hardware largely adheres to contemporary norms for all but vintage reissue-style Les Pauls: tune-o-matic bridge, aluminum stopbar tailpiece, Kluson-style Vintage Deluxe tuners with Keystone buttons, and larger strap buttons (yay!). Another feature here that some past Studio models lack is the cream pickguard, which contributes to the ’50s-era aura. There’s also a matching cream toggle switch washer in the included gig bag if you want to add another vintage touch.
Studio Play Date
Under the chrome pickup covers live two wax-potted, alnico 5 Gibson Burstbucker Pros, which are calibrated for their respective positions. The DC resistance for the Burstbucker Pro Rhythm is 7.8k and the Burstbucker Pro Treble 8.3k-ohms. They’re wired with a traditional Gibson four-knob complement and 3-way switch, but the volume knobs are push-pull controls that enable coil tapping, which broadens the tone palette considerably.
Playability is a high point. The fine setup, smooth fret work, and well-executed binding nibs lend a very visible sense of quality, but you can hear the payoff in the form of the well-balanced, resonant ring when you strum the guitar unplugged. When you turn it up, though, it’s classic Les Paul. Whether I paired it with a Vox-style head and 1x12, a Fender Bassman with a 2x12 cab, or numerous presets on a Fractal FM9, the Studio didn’t yield any negative surprises, but plenty of positive ones.
The Burstbucker Pros have plenty of bite. But most impressive for a Les Paul at this price, is the excellent clarity and articulation you hear along with strong hints of PAF-descendent grit and swirling overtones that lend heft and personality in cleaner amp settings. There’s none of the mud or mid-heavy boominess that you hear in some Les Pauls, even though the characteristically beefy Les Paul overdrive is present in abundance, helped, no doubt, by the slightly hotter-than-vintage-spec Burstbucker Pros. The Studio matches up well with a cranked amp or an overdrive. And while to some ears the Studio might not sound as creamy-complex or lush as high-end, vintage-leaning re-creations of a ’59 Standard, it will crunch, wail, and sing with aggression and civilized authority.
As for the coil-tapped tones, they don’t sound quite like genuine single-coil pickups, even though Gibson employs the nifty trick of wiring a capacitor in series with the coil tap—which is voiced to provide a fatter tapped-coil voice and balanced output with full-humbucking operation. It also provides hum-reducing operation when tapped and full-hum canceling operation when both are combined as they are reverse wind/reverse polarity. But generally, they will deliver the lighter jangle and chime that some humbuckers struggle with and lend a lot of versatility.The Verdict
From fit and finish, to playability, to sonic virtue and versatility, the new Les Paul Studio is a genuine Gibson USA-made Les Paul that offers a lot of value. It does just about everything a player working within this price range could want from a Les Paul Standard with a load of style to boot.
