The T-Rex Vulture started its life, when Michael plugged in one of the very first pedals we made. That pedal had a certain sound to it that we really liked, but it was a bit grungy in the low-end. We wanted to make a pedal with that sound, but with a tighter, less fuzzy low end and with more gain.
We opened up the pedal and painstakingly measured everything in it, to find out why it sounded so good, and found a couple of resistors that would be better with other values.
Was it modified earlier in life or was this just a very good sounding mistake from when it was made in Lars´ basement way back in the 90´s?
All we know is that the basic sound was cool and we left it at that, and went on to focus on getting the low-end tight - but BIG!
The fruit of our labor is a pedal that has a great, throaty distortion with a nice bite to it but the low end and low midrange can be shaped in many ways, thanks to the low- and fat-boost knobs. This allows the player to dial in almost stupid amounts of lows, but the distortion stays tight, not muddy.

T-Rex Mudhoney. We think the name pretty much says it all. Dirty and sweet. Delicious distortion. It’s one of first pedals we produced, and Mudhoney has all the tasty ingredients of a T-Rex classic: the perfect mix of controls, a rugged design, and astonishing tone. It’s been praised for its impressive tonal range and ability to deliver everything from a smooth dirty edge to a harrowing wall of distorted sound.

Chorus + Flanger gives you two must-have effects in one: a cool 80ssounding chorus and a freaked-out flanger. You’ll recognise both of
these classic effects right away, as you bask in the amazing vingtage
tone that’s made T-Rex the first choice for some of the world’s greatest guitar heros.
