the original 1176 is crazy expensive these days. i thought it'd be pretty elaborate, but looking at the original 1176 schematic, seems like a couple JFETs and a some BJTs. presumably the pedal removed the 5532 differential input. and the marketing doesn't mention any transformers so i guess they skipped that too. runs on +30V and -10V, nothing too crazy.
they're charging $359 for a pedal clone, and i bet most of that price is just based on the...
Inspired by the EP Pre-amp.. but it turns out the circuit is quite different to the Pre-amp portion of the EP..
it doesn't use the same values or voltages. :D .
Cute and compact little enclosure, but the build quality is pretty lousy IMO.
Why do they use the board mounted DC jacks with no relief when everyone knows how much trouble they can cause ?
Also, the only thing keeping the battery from the board tracks and DC jack is a cheapass piece of rubber and...
So. Anyone has any information on this one? It seems to be a nice sounding overdrive.
I stumbled on a blog post with a few photos, but there's not much that can be done with those. Anything more than guessing.
I'll throw in my 2c with speculating about the JRC4558 having 1N4148s and Schottkys in the feedback loop. Gain pot at A50K could point the gain setting to be closer to Marshall Bluesbreaker than a TS. 5 transistors in all, could be two AMZ mini-boosts or any other muamp...
Amptweaker's first pedal design... lots of similarities to the Tight Metal/Tight Rock, but stripped down a bit. Less gain, no noise gate, a bit less tone shaping, no switches.
i have apocalypse gut shots.. i'll give you a taste for now.. a quick explanation is the first function is just a twin t filter..second is the newer fuzz war circuit in the bottom right, third is the tl072 opamp, in between the 5 way rotary switch and the tone knob..the fourth is the octave clang circuit in the corner with the 741, transformer and Ge diodes in the upper corner..and then last one is called gain times 1000.. i have not traced down anything on this yet but i have schems for the...
This is the original version (the switch in the corner in latter versions is now a knob).
Apparently it is an amazing-sounding variant of the usual Big Muff, specifically set up for bass guitar and downtuning.
I'd love to see the reverse of the vero to see how it's wired up.
Hard to believe there is no info on this forum about the 25th Anniversary revision of the Way Huge Red Llama,
specifically the new HI CUT tone control. (The latest version of the Camel Toe also has the tone control in the Red Llama side of that pedal...)
I've seen references to, and questions about, the HI CUT control on the forums, mainly speculation that it might be some version of Mark Hammer's stupidly wonderful tone control .
I've experimented with the SWTC, and the response of the HI...
I can find anything schematic-wise, and I was seeking all bloody day...
It's just an audio patch (booster/compressor) part of the circuit, no wireless circuity included. Big-ass version is very expensive, but cheaper, more pedalboard friendly version is in works
i got this one a while ago- sorry for the shitty cell phone pix. i'll try and get some with a better camera soon.
it'a a 4 tranny fuzz with 2 2n222A's, and 2 MPSA18's configured in a rather odd way. maybe i'll try and give it the old RE soon, or if i can get some better pix we can all give it a shot.
nice sounding fuzz though, too bad about the e-tape!
If anyone wants to have a shot at tracing it, I'll take it apart and get detailed pics of everything in the next couple of days. I might have a go at it myself if I have the time next weekend.
I have one for a few days. I won't have a lot of time in those few days, but can probably take a few photos if there is interest. I won't desolder anything though - it's not mine. Can undo nuts etc though. It is a black board though, so might be hard to trace? I always find black boards hard to see. Anyway. I have put one photo of the assembled guts. Let me know if there is interest in more. It's a lot of SMD.
The P-2 was one of Pete's earliest designs (going back to 1981 according to Kit Rae) but to my knowledge it's never been traced. We knew the P-2 and G-2 shared the same PCB based on Dirk's FSB trace, and the P-2 was supposed to be closer to the Ram's Head than the G-2 which is voiced significantly differently than any existing Muff. But the only P-2 schematics seem to be speculative, i.e. taking the G-2 schematic and modifying it to be more like a Ram's Head. I don't think anyone has ever made...
According to Pete, the GC-1 (2021) is a completely new unique three stage design in celebration of 45 years in the music business. The description invokes the SS-2/SS-3 as well as the G-2/P-2, and talks about automatic switching between hard clipping and soft clipping... all of which would mean it's definitely not a CC-1, even though it looks a lot like one on the outside.
But yeah, it's a CC-1 with a few value swaps, so the product description is a lie. I expected better from Pete....
