Deluxe Treble Booster

This is a special build, and one that will not be done again any time soon. This rangemaster-style treble booster, built in a Marshall footswitch enclosure, features a BC109 transistor, Nichicon caps, a 3-position high pass filter, and external gain and bias knobs.

For ideal performance, roll down the volume knob (top), adjust the switch to set the high pass filter, adjust the gain (front) and bias (back) on the side to your preference, then use the volume knob up top to bring the output level to your desired level. Enjoy springy, crunchy, sizzling lead tones and more full rhythm tones with a treble booster.
