Lusithand 800BMF
The
800BMF is a full version of the 800BM preamp; it borrows the EQ section of the famous GK800RB amplifier and squeezes it into an onboard preamp, this time with a built-in Contour switch, on the Volume Control, for an increase in sound options.
The 800BMF differs from the 800BM by having an Active Blend and Master Volume control, making this a fully featured preamp.(not suitable for active/passive operation).
This tone stack has a very defined and clear tone to it. The EQ controls allow for 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.
The built-in Contour function works wonders at giving an instant new sound profile (think slap-switch), and it’s as easy as pulling up on the volume control to activate it and pushing down to deactivate it.
For a stripped-down version of the 800BMF, check the 800BM.
