Our Legacy Stage 3 Booster (the circuit that started it all)
Description
Our famous Legacy version of the Stage 3 Booster (the circuit that started it all)
For a modern version try the NostalgiTone Ascension Boost Circuit
Those new to our extraordinary Boost/Buffer circuit design understand it provides a transparent 25-30 DB Boost but really excels at making other circuits sound their best when used in tandem. It won’t color your tone but will allow you to get the most out of your pedal board and amplifier. By using the SW1 switch you can now “tighten” your tone to achieve those chugging rhythms.
It’s small size with on-board potentiometer allows it to easily be installed in a combo build neatly.
Works great with the Buff N Blend as a phase switch when adding multiple effects or a single effect that is non-inverting. You simply add the tiny Stage 3 Boost in series on a toggle and flip it for instant phase correction!
