Wanna boost ? 20db of clean boost, with a bypassable (left switch) preamp (bass and treble control). Right toggle let you switch between the original “Grind” or the “33” EQ.
This, is a three in one, including the old school popular Integrated Preamp, switchable with the left toggle.
In "P" (Preamp) position, Bass and Treble became active. In "B" (Bypass) mode, you only have Level and EQ type control.
Power consumption : 21mA
Voltage : 9Vdc ONLY, center negative. Anything over 9V will blow the pedal.

Customer Reviews
J’adore ma nouvelle pédale. J’ai l’impression qu’elle donne un nouveau souffle de vie à mes amplis. Merci Guptech.
Does exactly what it’s supposed to do. Sounds great and is quiet. Very solid build quality at an exceptionally reasonable price. Fast shipping to the US. Keep up the great work!
This pedal packs a lot of bang for your buck. It's basically like have three very expensive pedals, in one enclosure, and at such a great price. It can really help to tighten up an amp and boost the right frequencies going into your preamp. Very happy with this pedal.
