Almost ALL of those “tube pedals” out there run only on 12 volts and give NO tube gain at all. You get solid state transistor gain with a tube to LOOK at.
Most of the “tube” pedals out there are nothing more than over priced tube screamer circuits. The new D-MAX take the 12 volt power to light the tube and converts that 12 volts to 400 volts for ACTUAL TUBE GAIN
