ADA Offers Definition Guitar and Bass Preamp/Boost


ADA Amps Definition pedalThe ADA Definition Preamp pedal is designed to give a player greater control over their signal by effectively adding a stage that turns the first stage of a tube amp – normally the amplifying stage – into a distortion stage. With its footswitch-activated boost of up to +16 dB, it can deliver boost ranging form clean to full saturation, and uses a Class A design that includes an input impedance of 3 megohms, low-capacitance input, low-noise transistors and FETs, and a flat frequency response from 20 Hz to 40 kHz +/- 0.1dB. The pedal operates on 9 to 18 volts DC and is housed in an all-steel enclosure. Read more at
