REVIEWS

" Thank you Guy! I love this Overdrive Special you built for me.
Thank you for making it special! So beautiful and rich creamy—all of the above. The Overdrive cuts through the mix."

Mark Mancina 3 Time Grammy Winner - Film Composer (Lion king, Bad Boys, Moana, Tarzan & many more)

"Wow! From the start of the amp build process, Guy has been over the top friendly and helpful! When the amp arrived it was just as beautiful as the pictures I received along the way! Totally nailed the tone I was searching for without having to break the bank for other well known boutique amps that are on the market.

"Guy was very helpful and answered all my questions throughout the process. I loved being able to customize the look and wattage of my amp. Build and delivery were quick for a hand-built custom amp, and packaging was very secure. I would recommend this amp to anyone."

Dawson Farn 100 Watt Signature JM

" Can’t say enough good things about the excellent communication and customer service Guy provides. Spectacular feel, deep, round tone, rich cleans, smooth overdrive, and superb craftsmanship. For the price point and the level of customization available, you simply can’t do better. There’s no other way of saying it. These amps supersede similar styled amps at 5 times the price!"
