ARC Effects B3Verified
Based on the ARC Effects B3
From the post
This is ARC Effects take on the Burns Buzzaround with a negative voltage inverter to provide -9V to allow you to maintain a daisy chainable negative ground, but use the better quality PNP germanium transistors. This is a mojo version as per the first edition of the pedal.
ARC Effects make some fantastic pedals and has some of the highest build quality I've seen in commercial pedals, and I would wholeheartedly recommend their pedals to anyone if you're in the market for something they make.
