The classic amp simulator/overdrive pedal, the Tech21 SansAmp GT2. This is an early model (Made in USA) with the LED in the top center and no battery compartment cover on the back. Early models are said to have a slightly warmer sound due to different component configurations. I found it useful for getting a tube-like distortion even with the Jazz Chorus amps at rental studios, and it also faithfully reproduced amp-like distortion at low volumes late at night. I'm selling it because I'm changing my system. Please, someone, take it. - Operation confirmed (no scratchiness or unusual noise) - Shows signs of use appropriate for its age - All knobs and switches function normally - Works fine with both batteries and an adapter - The rubber feet on the back have been removed for mounting on a board - Non-smoking environment I will carefully pack it with bubble wrap and ship it within 1-2 days. It's a pioneer in amp simulation, and its unique character, unlike digital models, is still going strong. - Model Name: SansAmp GT2 - Brand: Tech 21 - Color: Black - Functions: Level, High, Low, Drive adjustment, Mode switching, Amp settings - Made in: USA Thank you for looking. #TECH21 #sansamp #GT2
