Description
The 800BM preamp borrows the EQ section of the famous GK800RB amplifier and squeezes it into an onboard preamp, this time with a Contour switch for an increase in sound options.
This tone stack has some serious high-frequency power and a very deep bottom end, just like the amplifier it’s based on, allowing you to explore different tones directly from your instrument.
The Hi-mid and Treble controls are highly interactive; the same goes for the Lo-Mid and Bass controls and the overall sound is always very “cut through” and clear sounding.
This preamps consists only of the Active components. This gives the user the chance to wire the passive elements (Volume, Tone, switches, etc.) to his preference.
For a full version of the 800BM, check the 800BMF.
