The Formula B Super Plexi Distortion is a two-channel overdrive pedal with a clean boost on one side and a Marshall JTM45 emulation on the other, using transistors to mimic the character of the tubes.
Each channel features its own footswitch, and a toggle switch lets you place the boost before or after the overdrive.
A tone knob, placed in the overdrive circuit, lets you tweak the signal EQ to your liking.
This is a pedal that’s getting some positive reviews from YouTubers, check out the videos below.
We added the Formula B Super Plexi Overdrive to our ultimate guide to the Best Plexi-Style Pedals.
This pedal has been built with the JTM45 circuit in mind, replacing the tubes with Transistors (unlike other pedals, using Opamps to emulate the tube sound)
Two standalone channels:
A = Overdive Plexi-Tone
B = Clean Boost
With a toggle switch, you can choose between: A on B or B on A. It’s like having two pedals in one.
FEATURES
A: Overdive Plexi-Tone
Level = Sets the output level
Tone = Sets the tone, from whole closed to wide open
Gain = Sets the amount of the distortion, from light crunch to heavy saturated tone
B: Clean Boost Just a single knob, increase the volume without touching the tone “SPLIT”
toggle switch:
When the toggle is “A>B”: With both effects ON, the overdrive is boosted (best when doing solos parts)
When the toggle is “B>A”: With both effects ON, the signal is boosted and THEN it comes into the Overdrive. (best when you want to fatten your tone, and make it more touch sensitive)
The toggle switch is not operating when you use a single effect.
You can run the pedal with a standard DC 9v (negative tip) True bypass switching
