Tone Shaping Articulation

"The DG Custom amps are the culmination of a three year collaboration between myself and Doug Sewell. We set out to create two distinct amps – a 30 watt and a 50 watt – that would rival the best of my vintage amps."

"After extensive designing, redesigning, and repeated comparisons to the amps I have cherry picked over the years, we have come up with two amps that I am blown away with. I've used them on hundreds of gigs and sessions and found them to be equally well suited to both live situations and studio work. Both amps do their own thing, and are far from knockoffs of any classic designs that boutique makers often strive for. I rarely play a gig when someone doesn't want to know what amp I'm using and the story behind it. I'm excited and proud that these amps are now in production. I'm hopeful that other players will find them as inspiring and musical as I do."

– David Grissom

“So easy to dial in; sounded great with all my pedals. It had a really great interplay between the master volume and the gain which seemed to be more of a blend and the EQ was very tweakable. Additionally, the calibration of the knobs was very gradual which is a very musical and useful attribute...it just rocked!”

- David Levita (Tim McGraw)

“I have owned and played some really great amps, but this amp is my favorite. Period. It is super articulate, very touch sensitive and good looking! But it can get as nasty as you wanna. And, I wanna.”

- Mike Squires, The Union Gospel
