Change R127 is weird. That is on the switching part. Why change it?
I noticed that as well and I think it has to do something with tone suck in bypass mode (of course I can't remember where I read that), but I'm almost positive I someone else doing that mod.

I'm going to say MA-150s, which were used in the original.

Re: Ts808 Tamura mod

"After painstaking analysis of hundreds of 808 variants, Mr. Tamura determined that the best-sounding units all featured a specific brand of IC, and that these IC’s were also from a specific production period."

Re: [Replica Files] Shin-ei/Univox Uni-Vibe

Hi folks, to make this short: i'm looking for the closest modern equivalent to the old LDR's used in the original Honey univibe - does anyone have info on the original's specs/measurements or can anyone confirm a successfull repair with replaced modern repros that seemed to keep the tone untouched?...

Biasing Q1 in a Fuzz Face... who does it and is it worth it?

Title says it all. What, if anything, do you feel it does to the overall sound?

Thanks!

They're claiming it was traced from one of SRVs personal TS-9s (guess we know who bought the one that came up for sale a few months ago).

Re: Shin-ei/Univox Uni-Vibe [Replica Files]

Hey Andre, Don't get too hung up on the photocells. One big pedal manufacturer claims that his are 100% dead on replicas of the originals when in fact, they look nothing like them. Grab a set from Small Bear (if they still have them) and focus more on gain and offset (hopefully you built yours with ...

Way Huge Camel Toe Series/Parallel switch... has anyone figured out how it works?

Hi,

I've been trying to figure out how Way Huge did the Series/Parallel toggle switch in the Camel Toe, either in the original or reissue. Has anyone traced that part of the circuit?

Thanks!

Re: Analogman - King of Tone [traced]

Having done some semi-extensive side by side testing with MA856's vs. MA858's, I'm going to throw my two cents in. Yes they sound similar, but the 856 is slightly sweeter and has a smoother decay. Tell me I'm crazy as much as you want but that's my experience.

Mr. Black - BB-74x clipping question. [traced]

I came across the schematic for the Mr. Black BB-74x and have two questions. 1) A couple of people stated it's a TS variant but I'm not really seeing that. Am I missing something? 2) What do the 100r resistors in series with the clipping diodes do, both from an electronically and sonically. Thanks!
