Dating proco rat pedal
Now I have a shiny new LM308 and I am VERY satisfied with my RAT!I added switches to select between 2x4148 clipping, 2x LED clipping and 2x Si Ge asymmetric clipping. It is cool to see the LEDs blink when I strum the strings.
The Rat is a heavy-duty fuzzbox that can take a lot of punishment and keep on working.
I used all recommended parts except for the very small capacitors when I used approximate values, but still close enough. La Rata is my fifth homebuilt pedal and my third tonepad build.
I used Xicon film caps, some from smallbear and some from effectsconnection. Because of its wide tonal spectrum, this is now my favorite distortion pedal.
It seems a bit odd to say that a distortion is smooth, but this thing is.
I build this once already using the pcb layout from another diy site and it was one problem after another. highly recommend using sockets for the ic and transistor. I used a SPDT on-off-on switch to switch from stock diode clippers to no clippers to MOSFET clippers.
