We are proud to donate a portion of every sale to Guitars4Vets to help provide music lessons to Veterans battling PTSD.

The output impedance is very low  and able to drive long cables without any tone loss. The output  transformer give an unique flavour to the sound: gentle high treble and  massive and defined low end.

Used on it’s own the ST81 can  correct for deficiencies in tone or signal strength of instruments or  amps; used in an effects chain the ST81 can correct or alter the tonal  characteristics of other effects units.

Used in the loop effects or  at the end of the effects chain is a perfect SOLO boost, you can set the  volume step and also the EQ for your solos.

Use higher voltage than 9V for far better dynamics and touch response.
