There is no better pedal for transparently driving a tube amp than the Supro Boost. 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 you to set the desired level of boost without sacrificing overall tone or adjusting your amp’s EQ settings to compensate.
The VOLUME control sets the output level of the pedal.
The three-way toggle switch selects between passive filters. The BRIGHT mode enables a 6 dB / octave 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 6 dB / octave low pass filter. This setting is useful for fattening up a single coil guitar when adding boost to increase warmth and prevent

harshness. When the toggle switch is put to the middle position, the filters are broken out of the circuit and completely bypassed for a flat frequency response.
The EXPRESSION jack accepts a 1/4” TRS cable from a standard expression pedal. The expression pedal controls the output volume of the pedal. With the expression pedal feature, the Supro Boost can act as an active volume pedal. The heel-down minimum volume can be set with an internal trimmer. The VOLUME control sets the maximum volume. Be sure to have the expression pedal plugged in when setting the minimum volume.
Your Supro Boost pedal comes equipped with a 9V battery that is accessible from the side-mounted battery drawer. A 1/4” TS cable must be connected to the input jack for the pedal to power up.
The Supro Boost can be powered with 9 ­18V with a center-negative DC power supply adapter. Running this pedal at 18V will give more headroom, more punch, and more output than if run at 9V.

The Supro Fuzz takes a “best-of-all-worlds”
FUZZ
approach to old school fuzz using both N.O.S. Germanium transistor gain and silicon-based gain to create a low-noise, high-octane fuzz box that will leave you deaf and breathless.

This groundbreaking analog pedal re-creates
DRIVE
the circuitry of a Supro amp from end to end, including a preamp, phase inverter, and an actual output transformer. The real tone of a genuine Supro amp has everything to do with the unique phase inverter design, Class-A power-amp section, and the magnetic saturation that occurs via the old-school transformers found in these vintage tone machines.
