SP 1303 Boost

BOOSTER

In addition to the classic tubecombos, Supro also features an effect pedal series. The SP1303 Boost Pedal is a J-FET-based cleanbooster that can boost the signal by up to 20 dB. The basic sound can also be adjusted to the guitar or the amp with the Bright / Dark switch. The highlight is the expression pedal connection, which allows the volume pot to be operated remotely - a minimum volume can also be preset internally by means of trimming potentiometers - thus the Supro Booster can also be used as an active volume pedal.
