Pimped out my route 66 once again!

[Pierre]

I got a little electronics package from a very nice guy from the DIY stombox forum (thanks to Martymart!) and therefore I couldn't help but pimp my route 66 tonight hehe...
Replaced the 4148 and 4148/Series LED in the clipping section by two 4002s...For which I had to snipp off the legs and solder new, thinner ones. Worked like a charm (thanks for the idea Rid, I thought I was too crazy for even thinking it before you confirmed sane people did it too! :laugh2:) and I put in a violet/blue LED for the OD section. So bright it almost hurt but at least they're not some kind of boring, invisible red now.

I lost a little openness and volume. I don't mind the volume loss at all as now it's actually more what I want of it. But the openness... well that shall be remedied soon by the inclusion of a TL072 opamp instead of that good old 4558 (though good is debatable).

With the already included bass boost, the route 66 is definitely probably the best TS circuit out there: because it doesn't sound as much like one :laugh2:

On that note I put a RC4558P into my HBE Powerscreamer (I have an original TS808 I bought 2nd hand in 1983 and a 808 modded TS7 both with JRC4558Ds) - it has a noticeably less smooth distortion and, well, more grit - so at the moment I like the variation.

I think I tried the P in my modded SD1. It started with a DD (I have 2 spare 4558DDs now which I don't know what to do with...), then a P then a TL072. The 72 just pwned both of them  8)

People worship the 4558 but I'm willing to bet they were chosen because they were cheap.
