I have become obsessed with modding tubescreamer pedals for bass and guitar, this is the little clipping switch I've developed for my Sonic Kitchen Tubes Creamer.
A bit fiddly to solder but a neat little unit that can solder directly onto any overdrive pcb to replace the 2 parallel clipping diodes in the circuit.
This is an ON/OFF/ON switch so when its in on position 1 it shorts out the 2 Si diodes and routes signal thru the LED diodes. In On position 2 it does the reverse.
On the middle OFF position it routes signal thru both sets which knocks the output way down.
The LED distortion is much higher volume raw gain, biting aggressive distortion, you can go from raw crunch to a splatty fuzz.
the Si diodes gives you the conventional Tubescreamer overdrive, much softer sweeter harmonics and lower output that you can compensate for with the volume knob.
Using the same switch and 2 different capacitors instead of the diode pairs, soldered direct to teh switch lugs, you get the great AMZ Phat mod which for me is essential for using the pedal effectively with the bass guitar. The jumper wires then replace the 0.047uF input cap.
On ecap choice remains at 0.047uF for the characteristic tubescreamer mid tone boost, the other can go up to 0.47 or 0.68uF to let a huge load of bass through which, to be honest, sounds fabulous!
