Electro Harmonix Deluxe Bass Big Muff Pi

The Deluxe Bass Big Muff Pi was an instant hit for me, it has an awesome fuzz tone, but the thing that really makes it worth the money is the extra features. The noise gate is awesome, because the pedal will pick up background noise from the guitar and amplify it. The blend knob adjusts how much of the clean tone you want mixed with the fuzzed tone. The crossover function on it allows you to make your clean tone more bass-y and your fuzzy tone more treble-y. With some adjusting, you can make it sound great on bass and also guitar. Adjusted correctly it can have an awesome fuzz tone with a lot of low end, which sounds awesome.
