Two-Rock Emerald 50 Tube Guitar Amp Head Bill Krinard Built & Signed #48225

Availability: In stock



WORKING CONDITION: Excellent -  All features are working perfectly. Another inspiring tonal masterpiece from the talented hands of Brill Krinard. It is everything you would hope in a Dumble-style amp, from the sky-filling cleans to glorious break-up and leads. 

PHYSICAL CONDITION: Excellent - There are some minor signs of use around the chassis of the amp, but otherwise very clean upon close inspection. Photos say it all! Note that some of the mini switches on the front have physical labels instead of screen printing, and one area has been black-markered. This is how it came from Bill and presumably the earliest prototype version of this amp.
