Reissue TS808, anyone modded it? (diodes, caps, resistors) not opamp swaps

[ericohman]

I bought a TS808 from ebay and the serial number is #0420051
First off all, I guess that makes it a reissue?
If you know about this, please chime in.

Anyway, I've watched this myth busting about opamp in tubescreamer-like circuits:

"Visual Sound: Myth Buster #2: Op Amps"

I'm more interested if anyone tried other diodes or caps, what were your experience?
I have no idea what kind of parts is in my pedal because it hasn't yet arrived. Maybe it's the same diodes as the ts808 from around 1980, I don't know what they did to the reissues really.

Any thoughts are welcomed, also if you've modded reissue TS9's

For what it's worth I built the GGG tubescreamer clone and ordered the mod pack with it. I built it to 808 specs with the opamp whose model number escapes me. I added the popular Keeley mod to it which sweetens things right up and added asymmetric silicon diodes, symmetric germaniums (sound beautiful) and symmetric LEDs in addition to the symmetric silicon diode clipping stages.

Regarding caps. All the caps related to tone I replaced with MKT capacitors for a more hi-fi sound. They're very nice capacitors.

Might replace asymmetric diodes with mosfets or something as the difference between the two silicon clipping methods are barely different. LEDs sound more clipped than silicon diodes. Think of a turbo rat. And they light up when you play too!
