A tiny little Distortion Generator that:
is a GREAT FUZZ/Distortion (with toggle switch set to "Flame" position)
is a Phenomenal clean-boost, and overdrive as well (with toggle switch set to "Spark" setting)
has something I came up with called Max-end-all 2 Band EQ: an excellent hi-cut with a great Bass control having the proprietary ability to bring in incredible sounding midrange when the pot reaches around 3 o'clock on its rotation.
can be so raw yet can be so refined, and so musically useable that it defies description and musical boundries..don't be confused when you see this on Country rigs and Top 40 pedalboards..sometimes you get lucky and develop something truly unique.

Recently added to Fulltone’s sprawling line of distortion pedals is the Catalyst ($159 street), a booster/distortion/fuzz that features Drive and Level knobs, a Flame/Spark mini-toggle switch, and two trimmer-sized knobs labeled Bass/Mids and Treble. As will all Fulltone products we’ve tested, the Catalyst is well made inside and out. The metal case is finished in hip looking orange paint and sports knurled screws that make it easy to open for battery replacement (a 2.1mm adapter jack for external power is also provided).
Tested with a Gibson Les Paul ’68 Black Beauty reissue, a PRS Mira and SC245, and a Fender Strat and Tele, the Catalyst ignited a bunch of cool tones. With the Gain control at it lowest setting and the mini-toggle in Spark position, the Catalyst is at its clean-boost best, capable of delivering an amp pummeling signal as you turn up the Volume knob. This is where you can get a classic “treble booster” response, which is great for coaxing wicked, ’70s-style distortion from vintage amps that don’t have a lot of front-end gain. Turning up the Catalyst’s Gain knob yields progressively more grind until a singing sustain is reached at the maximum setting. What’s cool is that the Volume control provides exactly the output level you need regardless of where the Gain is set. Switching to the Flame setting brings on way more gain and output, and is the mode to use for heavy crunch and lead tones. The Catalyst’s excellent 2-band EQ comes into play here to dramatically shape the character of these sounds. Fuzz tones are elicited by turning the Treble up past halfway, which intensifies the bite and summons the square-wave harmonics. Pulling back on the Treble and turning up the Bass/Mids control emphasizes the even-order harmonics to yield smoother and more tube-like distortion. This control also starts adding punchy midrange when set to 10 o’ clock or higher.
Once you get the Drive and Level controls in the ballpark, the EQ makes it easy to dial-in whatever flavor of grind you want—be it anything from Fuzz Face-style buzz to buttery-smooth sustain. The Catalyst never sounds mushy or compressed at high gain settings, and its dynamic response makes it possible to go from grinding rhythm tones to a blistering lead sound with a quick sweep of your guitar’s volume control. The Catalyst’s ability to do everything from super clean boosting to massive grind is impressive. This pedal offers some of the best characteristics of vintage booster and fuzz pedals—including lots of in-your-face presence—yet its flexible EQ and balanced response reveal the high degree of evolution in its design. No single pedal can do it all, but if you’re hunting for a distortion box that can cover a lot of bases and isn’t just another revamp of a vintage classic, the Catalyst is definitely something you’ll want to hear.
