The AXiom Overdrive Preamp OP-1 was designed to be the most capable, versatile, yet simple to use 100% analog overdrive pedal in existence. It can go from a tonally transparent boost to a traditionally-voiced overdrive to a full-on high gain metal preamp with the turn of a few knobs.
The OVERDRIVE control delivers classic overdrive tones, while the PREAMP control dials in a cascaded tube amp-like preamp section - it's like a vintage overdrive pedal and tube preamp in one. Along with carefully voiced BASS CUT and TREBLE CUT circuitry, the OP-1 can produce a vast range of light to crunchy to tube-melting overdriven tube amp sounds. It can be clean, fat, tight, mild or brutal depending on how you dial it in. Use it as you would a traditional overdrive pedal or as an accurately voiced "amp in a box" type preamp - the OP-1 is equally at home driving a tube amp into saturation as it is at making a sterile solid-state amp sound like a cranked tube head or a warm old tweed. From country to blues to metal, the OP-1 was designed to be the ultimate analogy overdrive/preamp pedal.
