The Pignose 7-100 Portable Amp is their original portable practice amp, complete with pig-snout on/off switch and volume control. The case opens for easy access to the amplifier's speaker and other insides. You can even have a friend fan the case open and closed for a wah-wah effect! The Legendary Pignose Amp also offers a preamp out jack for plugging those classic distortion sounds into an external power amp, PA, or recording console. This little Pignose is a quality-built amp with metal corner protectors, tough covering, and a rugged 6" speaker. The portable Pignose Legendary 7-100 weighs just 5 lbs and runs on batteries or its optional power supply.
