This old bird is bad to the bone.
The Hot Tubes' unique paracyclic filter makes it a most versatile distortion device. From warm overdrive to vacuum tube Big Muff sustain to the heaviest metal tube driven screams, you won't find a creamier distortion than the Hot Tubes. Powered by AC adapter and toroidal transformer that drives two Electro-Harmonix tubes to maximum voltage!
This is an excellent example of this piece of pedal history and will ship with the original box and power supply.
