The API Select TranZformer® GTR incorporates API's legendary EQ circuit into a versatile and compact guitar effects pedal. Designed to easily fit into your pedal board and engineered to run on standard 9V power supplies, the GTR offers +/- 15dB of gain on 3 specific frequencies. Additionally, the gain stage can be switched from Clean Boost to Overdrive mode to drive the input OpAmp and add even more tones to your arsenal. Other features include a buffered bypass, -20dB output pad, selectable peak/shelf for upper frequency range, transformer output, and of course the classic API sound.
