“This is Toneman Treble Booster by Don Butler. Beautifully hand made with quality parts (Germanium OC44 Transistor, Sozo caps, Allen Bradley Carbon Comps). Sounds great either in Treble mode or in the additional Full mode. Don Butler is no longer making these, because he says he can not find any good OC44 Transistors, so take advantage while these are still available.”
