I fear much of it will go over my head, but thanks for posting those two links @finebyfine, I'll endeavour to understand as much as I can, the interactive chip viewer is amazing.

Tell me you're not thinking of tracing it? And Yes I want one.

Not very exciting, but I think it's got to be 20+ years ago I got it.

I figure the differences are likely to be within the tolerances, but I’ll still double check the values just in case I slipped up. I’ve also just order a pair of LCR tweezers so I might open the Series 3 pedal and have a poke around when they arrive. Not that I suspect the schematic JHS...

I breadboarded the RAT over the weekend, Should I be able to hear a difference putting 30pF between pins 1&8 of the OP07? I know it’s needed for the LM308, but remembered seeing something somewhere that said it should be omitted on the OP07. I can’t hear a difference, but it’s not on a switch...

Thanks for you ideas on this Nostradoomus, I’d not though of the Clapton mid boost as a possible design route. It will be interesting to mock it up and see how it works into the RAT. Without really thinking about it I looked at the PCB, saw three diodes in what could be a asymmetric soft...

Hi @Robert, I noticed in another thread you seem to be exploring the idea of making a surface mount discrete op amp, and lets say hypothetically it is a LM308. Is the schematic in the specification document, complete? Only it says, “The inputs are shunted with back-to-back diodes for...

I had the opportunity to play my mate’s Rattler V2, and thought the boost was a very nice addition, once we’d taken it down from it’s default maximum. As far as I know it’s not been traced and I thought it might be a bit of fun to bread board a circuit that might give a close approximation of...

It is! I wish I’d had my Series 3 Distortion at the time to do a comparison, but it’s very RAT sounding, I just couldn’t say if it was exactly a RAT or just a very nice but different flavour! The boost was nice once it was taken down from it’s default maximum! But I feel a TS in front of a RAT...

I picked up a JHS Series 3 Distortion as I was curious about the RAT only to discover I really like them! I’ve got some OP07 op amps and I’m planning on breadboarding a basic RAT with symmetrical and asymmetrical clipping on a switch and combining it with the boost side of the Angry Andy Plus...

My mail seems to lack the excitment and wow factor that I see here, so I thought I'd lower the tone ;)

You're right, but I think that might have tipped me past my area allowance in Eagle, the free version is not overly generous! I’m trying to migrate over to KiCAD, so that should mean I can have as much space as I’d like, but I’m not finding the transition as easy as I though I would. For this...

I didn't have room for the charge pump :(

It's probably nothing, but just check this trace:

All my heroes played Strats, it was the only guitar I dreamt of, there are two iconic images that had a profound affect on me, the first was “The Cream of Clapton” album cover, very 80’s and the other is David Glimour’s red strat he played during the Pulse tour. My mum thought I might like the...

My only electric guitar for many, many years was a strat and I enjoyed discovering the tubescreamer, blues breaker, klon etc, then I got an Epiphone Les Paul 50’s and stopped playing the Strat, then I let the Strat go in exchange for a tele. Now my pedal board has a looper, tuner and delay...

Wow, we’ve seen three different Golden Fleece boards, the thing is with is the most authentic sounding, through hole with metal film resistors, through hole with carbon comp resistors, or surface mount with the mystery extra capacitor? ;)

Clipping diode orientation? Ignore me, I was looking at the wrong 808 on Pedal PCB!

I’m with you on the DGT Micheal but it looks like we’ll be waiting for about three months before we see them in the UK. My HollowBody II SE experience has really made me look seriously at what PRS is doing with the SE range. I’d also be tempted by the SE McCarty 594 in Black Gold burst, and...

Just had a second look inside mine, and apologies regarding the threaded section of the pots, mine too have three locking washers, damn hard to see with the mirror. So I was probably taking you down a rabbit hole unnecessarily, I’d guess the difference in pots is just an inventory thing and they...
