We’ve had the Scalpel Volume pedal available for years and the most common issue is that when the pedal is activated it decreases the volume. It’s often described as counter-intuitive and confusing which is entirely understandable. When your Fuzz pedal’s LED lights up you get MORE VOLUME. Overdrive : MORE VOLUME. Boost: WOO MORE VOLUME. So this light comes on and you cut your signal and ninjas your brain at the same time. With that said, this custom Scalpel has two different LEDs. When the pedal is bypass (full volume) you have your red LED. When the pedal is activated (volume cut) the LED is green.
