Orange Treble and Bass Booster

[rocket88]

got board today so i figured i would make some new layouts that i haven't seen posted. i did 3 different versions of the old orange treble and bass booster. 2 modded designs, 1 original. this is a PNP device, so you can only daisy chain this pedal is you use the layout with the charge pump or you put a separate charge pump in. all have a 1M pull down resistor to help prevent the switch pop.

made in the 70's, used by davide gilmour, rory gallagher, and wishbone ash, to name a few. closely related to the rangemaster, but with a passive tone control that blends the treble and bass.

original pedal


modded with bias trimmer and boost control like the rangemaster
