A streamlined approach for boosted-to-fuzzy dirt tones.
A pedal capable of distortion, boost and fuzz isn’t revolutionary. But considering how many of us string together endless combinations of those three pedal types on our boards, a streamlined approach is always intriguing. Mission Engineering’s Delta III Si isn’t a three-in-one box with independent fuzz and overdrive circuits cascading into each other, but a three-transistor analog dirt unit that can go from transparent boost to ballsy vintage fuzz with the twist of the gain knob. (The pedal employs silicon transistors, though Delta also offers a germanium version.)
Delta, this is Mission Control
You control the Delta III Si via four knobs. Lo cut and hi cut trim bass and treble, respectively. Level is a master volume control. Gain is the key to the Delta III’s varied personality, moving from boost to overdrive to full-throttle fuzz across its range. The footswitch is a quiet, soft-touch relay.
The lightweight, brushed-aluminum enclosure houses two printed circuit boards. There’s no 9V battery option, though you can power the Delta III Si with 7.5V-18V power supplies for the option of varied headroom. The pedal works best with a dedicated power supply—a daisy-chain supply can make the Delta generate a wall of locust chatter when the effect is engaged. But with the right power arrangement the Delta is extremely quiet at all but the most extreme gain settings.
Call in the Firepower
Mission Engineering touts the Delta III’s “friendliness” with other pedals. As with many fuzz pedals, my first inclination was the place it early in my signal chain, but I got the best results when I put it after an overdrive (an Amptweaker Tight Drive Pro). The overdrive excited Delta III’s crunchy output rather than adding stifling compression

With my Telecaster and the Delta III’s gain at 11 o’clock, I got Tube Screamer-like overdrive right at the cusp of crunch—an excellent setting for pushing a saturated amp over the edge. Note clarity is exceptional, and the pedal responds dynamically to changes in picking intensity. Digging in deep gives a blistering, amp overdrive-like edge. A lighter touch adds sparkling highlights and high-mid detail to chords and slower leads. However, that extra note definition means trebly guitars can sound super bright. That’s when the hi cut knob becomes invaluable. Setting it around 1 o’clock left plenty of room for my Telecaster’s top end to breathe, but kept shrieking feedback at bay when I stacked on extra gain.
With a Gibson Les Paul and an 18V adaptor, I checked out the available headroom. The higher voltage seemed to expand the tonal range of the darker humbuckers. The extra headroom meant more definition at high-gain settings. With gain at 3 o’clock and lo cut around 11 o’clock, I got a gritty, honky Les Paul drawl. Played with a slide, it was a straight shot of Duane Allman bliss. Decreasing lo cut at high-gain settings really fills out the bottom end—a cool tone option for the pedal’s fuzzier realms. And while the Delta doesn’t quite nail the brawn and sustain of a Big Muff, it’s still perfect for chunky ’70s hard rock power chords and stoner rock grind. You can readily move from fuzzier zones to civilized overdrive by trimming the guitar’s output. (This feels especially responsive with single-coils.)
The Verdict
The Delta III is a versatile dirt box that can wear many disguises. It’s a cool choice if you need one pedal to produce boost, overdrive and distortion tones, especially for travelling players requiring streamlined setups. It’s transparent enough to add definition and oomph to dirty amps without turning your tone into a saturated blur.The lack of switching options may limit the Delta III’s onstage usefulness for some players. But the pedal excels as a boost/distortion/overdrive you can quickly and intuitively tailor to suit varying guitars and amps. Given how readily it delivers everything from smooth crooning to fire and brimstone, the $199 street price is fair.

See and hear Taylor’s Legacy Collection guitars played by his successor, Andy Powers.
Last year, Taylor Guitars capped its 50th Anniversary by introducing a new guitar collection celebrating the contributions of co-founders Bob Taylor and Kurt Listug to the guitar world. The Legacy Collection revives five of Bob Taylor’s classic acoustic models, curated by the legendary luthier and innovator himself. “To imagine that we’re doing guitars that harken to our past, our present and our future all at the same time,” Bob says, “I really like that.”
In developing the collection, Bob preserved the essence of his originals while integrating performance and playability upgrades introduced during his tenure as designer-in-chief. “It’s an up-to-date version of what those guitars would be,” Bob explains, “but with the same sound.”
Visually, these guitars feel classic—clean, understated and unmistakably Taylor. While Bob’s original aesthetic preferences are showcased in his Legacy models, the nod to the past runs deeper than trade dress.
From his earliest builds, Bob favored slim-profile necks because he found them easier to play. That preference set a design precedent that established Taylor’s reputation for smooth-playing, comfortable necks. Legacy models feature slim mahogany necks built with Taylor's patented New Technology (NT) design. “My first neck was a bolted-on neck but not an NT neck,” Bob says. “These are NT necks because it’s a better neck.” Introduced in 1999, the NT neck allowed for unprecedented micro-adjustability while offering a consistent, hand-friendly Taylor playing experience.
What makes this collection unique within the Taylor line is Bob’s use of his X-bracing architecture, favoring his time-tested internal voicing framework over more recent Taylor bracing innovations to evoke a distinctive tone profile. Since Andy Powers—Taylor’s current Chief Guitar Designer, President and CEO—debuted his patented V-Class bracing in 2018, V-Class has become a staple in Taylor’s premium-performance guitars. Still, Bob’s X-bracing pattern produces a richly textured sound with pleasing volume, balance and clarity that long defined the Taylor voice. All Legacy models feature LR Baggs VTC Element electronics, which Bob says “harkens back to those days.”
The team at Taylor thought the best way to demonstrate the sound of the Legacy guitars was to ask Andy Powers, Bob’s successor, to play them. A world-class luthier and musician, Andy has spent the past 14 years leading Taylor’s guitar innovation. In addition to V-Class bracing, his contributions include the Grand Pacific body style, the ultra-refined Builder’s Edition Collection, and most recently, the stunning Gold Label Collection.
Below you’ll find a series of videos that feature Powers playing each Legacy model along with information about the guitars.
Legacy 800 Series Models
First launched in 1975, the 800 Series was Taylor’s first official guitar series. Today, it remains home to some of the brand’s most acclaimed instruments, including the flagship 814ce, Builder’s Edition 814ce and new Gold Label 814e.
The Legacy 800 Series features the 810e Dreadnought and two Jumbos: the 6-string 815e and 12-string 855e. Each model serves up a refined version of the Dreadnought and Jumbo body shapes Bob inherited from Sam Radding—the original owner of the American Dream music shop where Bob and Kurt first met. “I was making my guitars in the molds that Sam had made at American Dream,” Bob recalls. “There was a Jumbo and a Dreadnought. That’s all we had.”
All three Legacy 800 Series guitars feature one of Bob’s favorite tonewood combos. Solid Indian rosewood back and sides are paired with a Sitka spruce top, yielding warm lows, clear trebles and a scooped midrange.
Aesthetic appointments include a three-ring abalone rosette, mother-of-pearl Large Diamond inlays, white binding around the body and fretboard, and Bob’s “straight-ear” peghead design. Both Jumbo models also showcase a mustache-style ebony bridge—a nod to Bob’s early Jumbo builds.
Legacy 810e
The 810 Dreadnought holds a special place in Bob Taylor’s heart. “My first 810, the one I made for myself, was a thrilling guitar for me to make,” he says. “It’s the one and only guitar I played. It didn’t matter how many guitars we made at Taylor, that’s the one I took out and played.” The Legacy 810e brings back that bold, room-filling Dreadnought voice along with the easy playability expected from a Taylor.

Legacy 855e
Taylor’s first 12-strings found an audience in 1970s Los Angeles. “I was making guitars that would find their way to McCabe’s in Santa Monica and Westwood Music,” Bob says, “and these guitars were easy to play. Twelve-strings were a popular sound in that music. It was a modern country/folk/rock music genre that was accepting our guitars because they were easy to play. They also liked the sound of them because our guitars were easier to record.” The Legacy 855e, with its resonant Jumbo body, slim neck and gorgeous octave sparkle, carries that tradition forward.

Legacy 815e
The Legacy 815e revives Taylor’s original Jumbo 6-string, delivering a big, lush sound with beautifully blooming overtones.
Legacy Grand Auditoriums
In the early 1990s, Bob Taylor heard a consistent refrain from dealers: “Not everybody wants a dreadnought guitar anymore.” Players were asking for something with comparable volume but different proportions—something more comfortable, yet still powerful. This feedback inspired Bob to design a new body style with more elegant curves, more accommodating proportions and a balanced tonal response. The result was the Grand Auditorium, which Taylor introduced in 1994 to celebrate its 20th anniversary.
Thanks to its musical versatility and easy playability, Bob’s Grand Auditorium attracted a wide variety of players. “We came into our own with our Grand Auditorium,” he says. “People were describing it as ‘all around.’ It’s a good strummer and good for fingerstyle, but it’s not totally geared toward strumming or totally geared toward fingerstyle.” Also referred to as the “Swiss-Army Knife” of guitars or the “Goldilocks” guitar, the GA quickly became a favorite among guitarists across playing styles, musical genres and different playing applications including recording and live performance. “That guitar made studio work successful,” Bob says. It gained a wider fanbase with the debut of the “ce” version, which introduced a Venetian cutaway and onboard electronics. “That became one of our hallmarks,” says Bob. “If you want to plug in your guitar, buy a Taylor.”
Today, the Grand Auditorium is Taylor’s best-selling body shape.
The Legacy Collection features two cedar-top Grand Auditoriums inspired by past favorites: the mahogany/cedar 514ce and rosewood/cedar 714ce. Both models incorporate Bob’s original X-bracing pattern for a tonal character reminiscent of their 1990s and 2000s counterparts. Shared aesthetic details include a green abalone three-ring rosette, ebony bridge pins with green abalone dots, a faux-tortoiseshell pickguard and Taylor gold tuning machines.

Legacy 514ce
The Legacy 514ce features solid mahogany back and sides paired with a Western Red cedar top, yielding a punchy midrange and dry, woody sonic personality that pairs beautifully with cedar’s soft-touch sensitivity and warmth. It’s a standout choice for fingerstyle players and light strummers who crave nuance and depth. Distinct visual details include faux-tortoise body and fretboard binding, black-and-white top trim, and mother-of-pearl small diamond fretboard inlays.

Legacy 714ce
The Legacy 714ce also features a cedar top, this time matched with solid Indian rosewood back and sides. The result is a richly textured sound with deep lows, clear trebles and a warm, mellow response. Inspiring as it is, this specific wood pairing isn’t currently offered in any other standard Taylor model. Additional aesthetic details include green abalone dot fretboard inlays, black body and fretboard binding, and black-and-white “pinstripe” body purfling.
While the Legacy Collection spotlights Taylor’s past, newer models from the Gold Label, Builder’s Edition and Somos Collections show the company’s legacy is always evolving. Explore the Legacy Collection at taylorguitars.com or visit your local authorized Taylor dealer.

Our columnist’s silver-panel Fender Bandmaster.
How this longstanding, classic tube amp design evolved from its introduction in 1953.
I have a silver-panel Bandmaster Reverb that I don’t think I’ve talked about enough in this column. It’s one of the most versatile and flexible amps I own, so I use it for everything. It’s portable, has tube-driven reverb and tremolo, and has a full set of EQ knobs including the critical bright switch, which we discussed the importance of earlier this year (“How to ‘Trebleshoot’ a Vintage Fender Amp,” March 2025). The amp is not only pedal-friendly; the flexible 4-ohm output impedance will handle almost all speaker configurations and sound any way you’d like. Let’s take a deeper look at the Fender Bandmaster amp and walk through its development through the years.
The first Bandmaster was introduced in 1953 as a wide-panel tweed amp with Fender’s 5C7 circuit. This rare combo was loaded with a single 15" Jensen P15N and powered by dual 6L6GC tubes in push-pull configuration to produce a modest 25 watts. The 6L6GCs were cathode biased and along with the 5U4GB rectifier tube contributed to a forgiving sag, early breakup, and a midrange-y voice.
Fender made several changes when they launched that amp’s successor in 1955, the more widely known 5E7 narrow-panel Bandmaster, a well-proven amp that has come back as a reissue model. It was still a dual-channel amp—instrument and microphone—but the newer 5E7 model had a fixed bias and a negative feedback loop, providing a louder, firmer, and cleaner tone. Most importantly, the single 15" speaker was replaced by three 10" speakers, making it very similar to the narrow-panel tweed Bassman, the granddaddy of all Marshall amps. This Bandmaster had three speakers instead of the Bassman’s four, and it delivered 25–30 watts instead of 40. It offered early breakup with a midrange-y, big and full tone.
For those not acquainted with tweed amps, the volume and EQ knobs behave differently than on silver- and black-panel Fender amps. The volume pot can act like a distortion control, while the EQ knobs control the volume, and many players I’ve talked to have not really unlocked this secret. This works because, in these circuits, the volume pot sits right before the preamp tube, which allows it to push the tube into full distortion. Since the EQ pots are located right after and are capable of reducing the volume, you’re able to distort the preamp at low volume settings.
“Things became more standardized in 1964 with the arrival of the black-panel AB763 Bandmaster, an amp I have worked on a lot and appreciate for its robustness, simplicity, and versatility.”
In 1960, a short-lived and rare Bandmaster dressed in brown tolex and a black faceplate appeared with the 5G7 circuit. From here on, all Bandmasters had the modern top-mounted chassis. With this circuit, the Bandmaster started to both look and sound more like a black-panel amp. It kept the 3x10" speakers but got a diode rectifier and bigger transformers resulting in a 45-watt output. Tremolo was introduced for the first time, and both channels were now intended for guitar.
The following year, a blonde 6G7 Bandmaster followed as a smaller amp head paired with a 1x12 extension cabinet. It had the timeless early blonde looks with cream tolex, brown faceplate, oxblood grill cloth, large Fender logo, and white knobs. But halfway into the blonde era, towards 1964, things turned strange and rather confusing. There were suddenly two 12" speakers, black knobs, a wheat-colored grill cloth, a more slim black-panel-style Fender logo, a black faceplate, and all in various combinations close to the transition into ’64.
Things became more standardized in 1964 with the arrival of the black-panel AB763 Bandmaster, an amp I have worked on a lot and appreciate for its robustness, simplicity, and versatility. It offers a pure, clean, scooped black-panel tone that’s somewhere between a Vibrolux Reverb and Pro Reverb, which share the medium-sized 125A6A output transformer and dual 6L6GC tubes. With its medium/high power and flexible 4-ohm output impedance, it can drive all kinds of speaker cabinets—as long as you stay between 2 and 8 ohms, you are safe.
For a short time in 1967–68, there was a transitional Bandmaster with aluminum trim and black-panel innards before the all-new silver-panel Bandmaster Reverb replaced it in 1968. The small-head cabinet had grown in size and, unfortunately, weight to accommodate the reverb tank. The amp got a 5U4GB rectifier tube along with a few general silver-panel changes to the circuit. Several silver-panel models existed with minor differences until a 70-watt beast version came along in 1977 with master volume.
To my own 1968 Bandmaster Reverb, I have done a few adjustments. First, I made a custom baffle to hold two 8" speakers. I installed a pair of WGS G8C speakers that fit perfectly on the baffle board without colliding with the reverb tank or transformers. Sometimes, I use only one of the 8" speakers for bedroom volume levels. Second, I reversed the bias circuitry to standard AB763 specs, making it easier to adjust bias correctly on both power tubes. If you are into sparkling clean and funky Strat sounds, you would love this little 2x8" combo.
