Seymour Duncan Twin Tube Classic Pedal

[robberns]

Great sounding pedal that cover everything from mild-crunch blues to screaming metal overdrive. I have 2 of these pedals, this was my backup that I never needed.

Includes the original box, power supply, has velcro applied to the bottom. Pedal is in excellent condition and low-hours on the tubes (which are military-grade and will probably outlive most of us).

$110 shipped in the CONUS.
