The Pete side is designed to sound like a vintage tube amp from the 60′s and 70′s. These tones have become legendary in the minds of all rock guitar players. The controls are very simple and straight forward. The output knob controls the effected output level going to your amp. The input level is controlled by your guitar's volume knob – just as it is when you plug into a vintage amp. By adjusting your guitar's volume control you can drastically change the tone and response of the pedal and we encourage you to experiment in this area. The year knob determines the amount of gain you send to the pedals overdrive circuit. By rotating the knob clockwise, towards '77, the sound becomes more distorted producing a rich harmonic texture. This will enhance every note and chord you play, especially power chords…very cool! And just like a vintage tube amp the clarity of each note can still be heard. The circuit is also very touch sensitive responding to your own personal playing style. The tone switch was added to allow you to roll back some of the lower frequencies. Depending on the type of pickups you have in your guitar, this switch can really help put the finishing touches on your sound.
The Jimi side is one of the best sounding fuzz faces on the planet. Just like the Pete side the controls are simple and easy to use. The input pot controls the amount of signal coming into the pedal. The output pot determines the amount of effected signal that is sent to your amp. The Haze control determines the intensity of the fuzz saturation. Unlike a conventional fuzz control, which is typically found on many Fuzz Faces, the haze control and the input control work together in shaping your sound. Depending on how the two are adjusted you can go from a voodoo wall of Fuzz to one of the sweetest sounding overdrives in the galaxy. The tone switch functions identically as it does in the Pete circuit, offering you even more tone shaping flexibility. Don't be afraid to play with your guitar's output control too. Unlike most fuzz faces the Jimi won't get too thin when you turn your guitar's volume down.
The true flexibility of this pedal lies in the fact that we designed both sides to work together. Although they're two different circuits, one can be made to sound similar to the other. In other words there's a little yin and yang thing going on here. That's why the color of the LEDs is reversed. Put it all together and you get the Fuzz Bubble-45!.
