I have a 02 TSL and replaced the mainboard, but aside from the clean tone sounding great, the crunch and Lead tones sound meh. I bought a classic tone PT in hopes it would improve the sound, though I do not know how to read schematics. Would you be able to help me with it? I need a general diagram on how to wire it. was told to buy the JCM 900 PT for it as it has more output. here is the schematic for the PT.
