BMF Effects GB Germanium Boost. The GB is BMF Effects’ take on the Dallas Rangemaster treble boost (so there is a germanium transistor in there) with a couple of improvements. The tone knob allows the user to sweep from bass to treble allowing for a wide range of tones and it can be powered by a standard 9v negative tip adapter as it converts to positive ground where needed internally. Also equipped with an LED, power filtering and true bypass switching.
