The FET PreAmp is a replica of the BOSS FA-1 FET AMP. It includes a true bypass footswitch for on/off functionality. The kit comes with Hitachi HA1457W OpAmps and an NOS Toshiba 2SK246 JFET, the same semiconductors used in the original FA-1. It also features higher quality components such as 1% metal film resistors and higher quality film capacitors.
