Teisco

The Teisco Boost is an effects pedal based on a vintage preamplifier. It has a FET (field-effect transistor) to give it softer, more organic clipping and mini switches for changing the voltage and selecting different boost modes.

The Teisco Fuzz makes use of a traditional silicon circuit and adds a switchable upper octave to give you an unbelievably wide scale of wild '70s sounds ranging from blistering lead tones to gnarly textures to synth-like overtones.
