F-PRE - Fender-Style Preamp Kit

F-PRE is the classic North American style of clean preamp: two gain stages with an EQ and level control in between. The sound of Fender amps, surf music, classic warm clean sound with sweet sustain. The magic of a single 12A_7. This is the standard Fender circuit, used in their entire line after about 1963.

Combine F-PRE with M-PRE and/or Z-PRE and a switching system (ERK or QRK) to have a multi-voice preamp.

Controls:
• Volume
• Bass
• Mid
• Treble

On-board muting points are provided for switching between F-PRE and other preamp channels in a multi-channel system. Each gain stage is decoupled for very-low-noise operation.

Power requirements:
Heater: 12V at 150mA or 6V at 300mA, AC or DC
Plate: 160 to 450Vdc at 2mA
