While many overdrive pedals are happy to deliver some dirt, the .45 Caliber specifically aims to nail the classic Marshall 1962 JTM45 tone.
Going further, J Rocket namechecks Malcolm Young's rhythm crunch, and Pete Townshend's sound on The Who's Live At Leedsas inspiration for the creation of this pedal. Big words.
Plugging in a '67 Gibson SG Jr for a classic Townshend vibe, we're impressed by how the .45 Caliber reacted to the dynamics of our playing.
It sounds like a great 60s valve amp, with a pleasing amount of compression when you dig in for lead stuff.
