Key Features
Product Ref: 71623
Supro’s SP1303 Boost Pedal is a J-FET based pedal design that delivers up to 20dB of gain without adding any unwanted background noise. The pedal offers a straight forward and effective boost that stays sweet and clean on all settings, no matter how hard it’s pushed with other pedals earlier in the chain. The Boost effect remains frequency linear, even when the gain is adjusted, this allows the boost to be used at the desired level without losing tone or the need for EQ adjustments.
The pedal’s preamp also features high and low pass filter options that can be accessed via the 3-way toggle switch. The toggle switch has three different modes; a bright mode, a flat mode, and a dark mode. The bright mode enables a 6dB/octave high pass filter that thins out humbucker guitars when adding boost to increase sparkle and prevent any mud. The dark mode enables a 6dB/octave low pass filter that fattens up single coil guitars when adding boost to increase warmth and prevent harshness.
The Supro Boost features a TRS port in order to attach an expression pedal to control the boost’s volume knob. This turns the Boost Pedal into a high-fidelity, active volume pedal with user-adjustable minimum and maximum settings. When the expression pedal is in use, the boosts on-board volume knob sets the maximum value while a user-adjustable, internal trimmer sets the minimum volume.
