Supro Boost is a “clean” pre-amp ideally suited to pushing the front end of a tube amp. This J-FET based pedal design delivers up to 20db noiseless gain boost plus optional High Pass or Low Pass filtering to contour your sound. Simple, straight-forward and effective, the Supro Boost pedal remains clean and sweet at all settings, no matter how hard you push it with other pedals earlier in the chain. The Supro boost also remains frequency linear as the gain is adjusted, allowing the musician to set the desired level of boost without sacrificing overall tone or requiring them to adjust their amp’s EQ settings to compensate.
The Supro Boost pedal sports a simple control layout with a single Volume knob and an oversized toggle switch to select BRIGHT, FLAT or DARK overall frequency response. The BRIGHT mode enables a 3db/octave HP (high pass) filter. This setting is useful for thinning out humbucker guitars when adding boost to increase sparkle and prevent mud. The DARK mode enables a 3db/octave LP (low pass) filter. This setting is useful for fattening up single coil guitars when adding boost, to increase warmth and prevent harshness.
Taking the boost pedal one step further, the Supro Boost offers a TRS port for expression pedal control of the VOLUME knob. This effectively turns the Supro Boost pedal into a high-fidelity, active volume pedal with user-adjustable minimum and maximum settings. With the expression pedal in use, the on-board VOLUME knob sets the maximum value while a user-adjustable, internal trimmer sets the minimum volume. All Supro pedals are assembled in Port Jefferson, NY, USA, featuring custom-tooled, anodized, brushed-aluminum enclosures, 9V battery or AC powered operation, rear-mounted metal jacks, easy-access side-mounted battery drawer and studio-friendly, noiseless (click-free) true-bypass switching.

I like this units with the possibility to control its gain via external expression pedal and we already have some nice options to consider in this field: the Vexter Boost (which for me lacks of tonal options and would like its buffered based operation to be an option instead of its stable condition), then the Ernie Ball MVP (which lacks tonal options, too), then the Moog MF Boost (which I already bought based on its flexible features) and now this one by Supro (company that also has an overdrive and fuzz with similar external expression capability, mostly for the drive as it also handles the gain) which has a kind of mixed implementation of features. I I like the idea of the Supro making it able to switch the options from neutral (something that the MF Boost is not able to) to the possibility of cutting the low or high frequencies, the MF Boost also has Gain and Volume controls which has some sense but can result a little redundant too by making of the second a sort of leftover so I like the idea of the Supro of having just a Volume knob which also results in some more focused/limited controls to achieve what I want with no additional kind of depreciable/redundant knobs going around.
