Though he formed JT Sound Inc. a mere four years ago, John Tomaszewicz has been pursuing his passion for innovative tube amp designs since the early 1970s. An electrical engineer by training, John spent the early part of his career working for a large electronic manufacturer designing and testing a host of electrical circuits. After teaching himself tube amp design, John took the lessons learned from his day job (along with access to expensive electrical testing equipment) to begin designing tube amp circuits that “take the next step forward” rather than mimic a particular vintage vibe.
As a gigging guitarist and recording engineer, John wanted his amps to meet the goal of having exceptional clarity, responsiveness and enhanced frequency response. The result is an amp designed to excel in both the studio and onstage. An emphasis on reliability and serviceability are also incorporated into the design through the use of components that exceed their respective ratings.
The Benefits of Innovation
While the circuit design of the TZZ-15112 is unique, its aesthetics borrow from some timeless designs. Out of the box, the amp has a striking resemblance to the venerable Marshall 1974X 1x12 Combo, with its expertly applied black tolex covering, contrasting white piping and “Bluesbreaker” colored grille cloth. The top-mounted chassis utilizes a combination of black studio knobs (Cut, Gain, Sustain, Master Volume) and white “chicken-head”-style knobs for its passive tone stack (Bass, Middle, Treble, Presence) and Pre Amp Gain controls. The use of black and white knobs is a thoughtful design decision, as it proves useful in adjusting levels in low light conditions. The black control panel is finished off with a single input, indicator light, standby switch and power switch. The rear of the amp features an open-back cabinet design and with an effects loop, 4 and 8 ohm outputs, power input and a pair of fuses. All in all, a very attractive amp—my only quibble is that it lacks corner guards to protect it when you take it out to be heard.
Under the hood, its overall design reflects the hand of an experienced amplifier builder. The cabinet is made from 13-ply Baltic birch and features 1/4" finger joints. Situated in the cabinet is one 12" Veteran 30 speaker from Warehouse Guitar Speakers, LLC. This US-based direct seller of speakers produces well-executed versions of classic speaker models. According to WGS, the Veteran 30 takes all the goodness of the Celestion Vintage 30 speaker with a tonal improvement smoothing the “spike” in the uppermids. Housed in a spot-welded chassis made from heavy gauge aluminum, the circuit is constructed using a printed circuit board to maintain consistency, as well as point-to-point wiring for the chassis-mounted tube sockets. The amp’s modular design makes servicing easier for techs.
With an emphasis on reliability, TomasZewicz does not use any relays or switches in the circuit (other than On/Off and Standby) and every component used in the circuit has ratings that exceed the voltage and temperature environment over the required frequency band. Although TomasZewicz believes superior performance is achieved in the circuit design versus components used, the amp features a beefy custom Pacific power transformer (with two extra taps for the sustain circuit), an ultra-linear Hammond output transformer, PEC pots and Sprague Orange Cap Drop capacitors. The amp also features an array of JJ tubes that include a pair of EL84s in the power section and a 12DW7/ECC832 in the preamp, followed by one 12AX7/ECC83 and then three 12AT7/ECC81s for the makeup gain stage and the tube-buffered effects loop. The phase inverter tubes are run in parallel, adding a level of smoothness and fatness to its overall tone (think Matchless). Its cathode bias design does not require re-biasing, so tube tweakers can rejoice accordingly.
The TZZ-11512 has some interesting features that are worth noting. The integrated Sustain feature on this amp is a studio-quality design: a dynamic control device that offers just the right amount of compression with a hint of drive. It works in tandem with the Drive control to push the power section on the amp to the desired level of breakup. These controls could easily be sold separately as a discrete effect. The Cut knob acts as a low-pass filter on the power amp, and Presence offers more crispness to the overall tone. The Pre-Amp Gain knob adds an articulate, smooth drive tone that sits somewhere between a Vox- and Plexitype overdrive. The tube-powered buffered effects loop sounds great with no treble loss.
I took John’s advice and put all the studio knobs to zero and began dialing in certain tones. Pushing the Sustain and Drive up in tandem with the Pre-Amp Gain set around 3, I was instantly greeted with a tone that was filled with EL84 chime laced with tasty harmonics. Think REM- or Early Tom Pettytype tones. The passive tone stack also acts as a Volume control, and bringing up their respective levels brought out the responsiveness and articulation of the fundamental tone. With so much sustain at my fingertips, I found myself playing single-note lines at an ever slowing pace to enjoy the harmonic complexity of each note. Pushing the Pre- Amp Gain along with the Drive and Sustain knobs revealed a more-than-adequate power section with no discernable “sag,” as power chords barked with authority and solid string separation. I found the amp easily capable of handling both single-coil and humbucking pickups, with my favorite being a Nash “Keef” Tele loaded with a Lollar Special pickup in the bridge that consistently offered up a pleasing blend of drive and chime.
The Final Mojo
I was able to jam with the amp with another guitarist and a drummer and found the amp sat well in the mix. The amp’s responsiveness was evident as small changes in pick attack and guitar volume control brought substantial changes in overall tone. At times I found myself wanting more clean headroom with slightly less hum, but I’m sure TomasZewicz’s higher-powered EL34 heads and combos could offer the additional sonic real estate. It is great to see an original amp circuit in a “saturated” amp market; I suggest folks consider TomasZewicz’s offerings.
you’re seeking classic rock/blues tones that “cut through the mix” with articulation, harmonic complexity and tremendous sustain.
you require two channels, reverb or copious amounts clean headroom.

DiMarzio, Inc. announces the Relentless P (DP299), the Relentless J Bridge (DP301), Relentless J Neck (DP300), and the Relentless J Pair (DP302) for 4 string basses.
DiMarzio, Inc. announces the release of the Relentless P (DP299), the Relentless J Bridge (DP301), Relentless J Neck (DP300), and the Relentless J Pair (DP302) for 4 string basses. The new Relentless P and Relentless J series pickups feature the Relentless cover designed in collaboration with Billy Sheehan.
As with the Relentless pickups, we removed all the hard edges from the standard P Bass and standard J Basspickups, and added an arch to the top of the pickups to bring the sensing coils and pole pieces closer to the strings. These improvements increase the dynamic range and make active circuitry unnecessary.
The Relentless P and Relentless J pickups incorporate Neodymium magnets and produce 70 percent more output than traditional passive pickups, and they’re dead quiet due to the incorporation of metal covers and foil-shielded cables. To dial in (or fine-tune) the individual string output, the Relentless P and Relentless J include eight adjustable pole pieces. These pickups also have a broad magnetic field so you can even bend notes without volume dropout.
DiMarzio’s extra shielding makes the Relentless P and Relentless J better for both recording and stage performances. We’ve mounted them onto robust .09375” thick circuit board base plates to eliminate the annoying protruding mounting screws — ultimately creating a more comfortable and consistent foundation to rest your fingers on.
The new Relentless P steps beyond the traditional P-Bass sound and can only be described as massive. It has more of everything: more volume, beefier lows, a growling midrange, and crispy highs with better individual string definition.
The Relentless J incorporates a new invention, (patent pending) parallelogram-shaped coils, offering an expanded mid-range punch, snappy highs, precise lows, and a new dimension to the sound of the Relentless series pickups.
Relentless P and Relentless J pickups will breathe new life into any bass, increase playability, and work well for any style of music from Motown to metal.
DiMarzio’s Relentless P, Relentless J Bridge, Relentless J Neck, and Relentless J pair are made in the U.S.A. and may now be ordered for immediate delivery.
Suggested List Price for the Relentless P is $169.00 (MAP $119.99).
Suggested List Price for the Relentless J Bridge and Relentless J neck is $155.00 (MAP $109.99).
Suggested List Price for the Relentless J Pair is $296.00 (MAP 209.99).

Featuring the Adaptive Circuitry recently introduced on their Halcyon Green Overdrive, Origin Effects have brought us a pedal with a character all of its own and a new flavor of drive.
Origin Effects introduce the new M-EQ DRIVER mid booster & drive pedal. Based on a vintage Pultec studio EQ, this unique pedal offers a range of mid-focused tones, from a subtle mid boost to thick, resonant overdrive. Featuring the Adaptive Circuitry recently introduced on their Halcyon Green Overdrive, Origin Effects have brought us a pedal with a character all of its own and a new flavor of drive.
A choice of three mid-range frequencies ensures that you can boost just the right part of your guitar signal and, when pushed harder, can elicit a range of saturation from a classic “mid-hump” overdrive to fierce “cocked wah” distortion. Thanks to the Adaptive Circuitry, the high-end roll-off of the Cut control is reduced as the pedal cleans up. This allows for a smooth transition from warm overdrive to bright clean tones in response to playing dynamics or guitar volume knob changes.
Introducing... M-EQ DRIVER || Mid Booster & Drive
Built-in the UK to the highest standards, the M-EQ DRIVER continues the Origin Effects tradition of vintage, studio-inspired tones in modern guitar pedals. The Origin Effects M-EQ DRIVER is available now from Origin Effects dealers worldwide.
RRP: 259 GBP (Inc VAT) / 319 USD (Ex TAX)
