For the discerning musician, i am offering up for sale my Electro Harmonix English Muff'n. Two 12AY7 valves make for a great preamp or simply use as an overdrive pedal. You can easily swap out the valves for 12AX7s or 12AT7s or a mixture of whatever you want, cascading into the other. As used by the likes of John Frusciante and others. Comes boxed with power supply, as pictured.
What they say:
British invasion! Taking its roots from legendary British guitar amps, the English Muff'n recreates their majesty and classic tone with spot-on accuracy. Rather than approximating these amps like "emulator" products, the English Muff'n employs vacuum tubes to produce the richness and natural saturation of Brit-valve sounds. A bloody masterpiece!
"Its clean tones are nothing but inspiring. Delivers tea-riffic Brit-tones that turn your amp into a British classic." -- Art Thompson, Guitar Player
