3 Monkeys Grease Monkey Amp

guitarinteractivemagazine.com

The 3 Monkeys Grease Monkey II amp is a boutique gem that combines stunning retro aesthetics with impeccable build quality. This 30-watt, hand-wired valve head is a tonal delight, offering a rich range from clean to classic British crunch, thanks to its meticulously crafted components. The controls, featuring vintage-style knobs, provide precise tonal shaping, with the standout being the versatile shape control. While it lacks modern features like an effects loop, its organic and responsive sound more than compensates. Though expensive, it's a worthy investment for serious players seeking top-notch sound and durability.

Q: What amps are you using?

EM: I primarily use a killer 30 watt Suhr Badger and a Fender Deluxe modded by Bill Krinard that’s great. I also have Custom Audio Electronics amps, Three Monkeys GM II and some old Mark III Boogies that Boogie restored for me.
