Paul Cochrane Timmy Pedal
The Timmy has gain/bass/treble/volume controls. The Bass and treble controls are "cut" style controls. That means that as you turn them clockwise they will roll off the bass and treble frequencies. Zero (7 o'clok) is flat - not cutting any frequencies. It seems backwards, and it is! The reason for this is the taper of the pots. Having them turn the normal way would have big dead spots in the rotation. Plus the fact that setting gain/bass/treble all to zero sets the pedal up for a flat clean boost. Unity gain is about 1 o'clock on the volume. It's really simple once you get used to it.  The bass control is pre distortion. Most pedals roll off the low end before you distort the signal to keep things tight and clear. A lot of low end distortion can get real muddy real quick. But what that means is you don't have the low end there when you ned it for cleaner settings. the Bass control will allow you to keep the low end for the cleaner sounds, and dial it out for the crunchy stuff.  The treble control is post distortion. Like the bass circuit most pedals will have a preset high end roll off to keep the pedal from being fizzy and noisy when distorting, but you'll lose the highs for the cleaner settings. So for cleaner settings you might have the treble on zero for all the highs, and as you turn up the distortion you would roll back the treble to keep things smooth.  Being able to control the pre and post EQ gives you the ability to kill the mid bump a lot of pedals have preset into them. You might have them on zero (7 o'clock) for the cleaner stuff, and rolled back to something like 3 o'clock for the distortion tones. A good starting point is to set the bass and treble controls to the same setting as the gain control, and then tweak from there. Don't be afraid to roll them all the way out! The 3-way toggle switch for different clipping options. The middle and down positions are symmetrical clipping settings, while up if an asymmetrical setting.
