The 800 BMF preamp borrows the EQ section of the famous GK800RB amplifier and squeezes it into an onboard preamp while making it lower impedance through-out for quieter operation.

This version, designated, Back Mount Full highlights the inclusion of a matched Active Blend Control & Volume circuit, for the ultimate installation.

Being a Boost-Cut preamp, the Hi-mid and Treble controls are highly interactive; same goes for the Lo-Mid and Bass controls and together with the Contour switch allows for a palette of sounds at the tip of your fingers.
The preamp is set for approximate unity gain and there is a Gain trimpot that allows for a little bit of boost on the overall audio signal.


An important feature of this preamp is the ability to choose how you want your stacked potentiometers to function since these have connector cables. It is up to you if treble goes on top or bottom of the potentiometer or if you want to pair the Hi-mid and Treble on one pot and Lo-Mid and Bass on the other, it is, ultimately, your choice.

The potentiometers are labelled "top" and "bottom" while, on the motherboard, "Hi-mid"; "Lo-mid"; "Treble" and "Bass" are also labelled for an easy and intuitive installation.

Potentiometers: x2 dual concentric (10mm bushing height, 8mm ⌀) top = 6mm ⌀; bottom = 8mm ⌀ Switch: 6mm ⌀, 9mm bushing height
