Our Preamp+Boost is the fantastic, now discontinued DOD FX10 Bi-FET preamp. This pedal is suitable for any instrument, giving you up to 17 dB of clean boost and a tone control that functions as a bass boost when left of center or a treble boost right of center. 
 
Each pedal is  hand built using high quality Neutrik Rean jacks, Nichicon electrolytic capacitors, 1% metal film resistors, and a Pro grade footswitch for years of trouble free use. Bench tested and satisfaction guaranteed.
