The clone had premium caps as well. May 24, 5. Some ICs when overdriven sound more musical than others. Nachoman, It looks like we’ve forgotten about you, but that is not the datashwet.
If they are starved, the chips meet all published specs and give nice low power consumption, but garble the fine detail in good audio.
The in a Tube Screamer does have a sound that is good and is what a lot of people find vatasheet their liking. Some circuits sound better with inferior spec’ed chips. I put this in the same piles as some of the capacitor, resistor and conductor stuff floating around.
Great points made, truly. The old pedal was not superior to the new one in any way, in fact, it was inferior in ways.
It’s descended from the single and the dual. The can be criticized for not being fast enough for clean high-level audio. Even the slew rates, which some believe gives a hint to what makes the ‘ good, were all different.
These 3, in particular, sounded really, really good. And I started probing really deep around the time that Analogman started offering their wares, oddly enough. Just search the metas; there’s lots of info on opamp upgrades.
Sometimes I think I’m dyslexic. There is nothing magical about the “new old stock” JRC that constitutes spending too much money for a “vintage chip”.

The is a standard dual opamp. I am begining to think it datxsheet a run of a somewhat defective part that justs sounds good. I’ll look up some Dual Op Amps. And “minor” chip redesigns that do not affect the “normal” performance can make significant difference when you go outside the normal range.
I don’t think we’ll see a pedal guru doing any sort of semi-scientific chip preference test any time soon though May 24, 6.
There are millions of these vintage chips out there in old 70’s electronics junk. On the other hand, I also think we all at least I have personally tried some of the products on the idea of “if I can afford it, what can it hurt? Remove the compensation cap and put a TL in there with the rest of the circuit unmodded and it sounds awful. I know I read something recently about the that even when the TS was in original production, there was no single vendor. Even in an 8-in board, the difference between TL and power demand will make a big difference in power supply size and cost.
Back when my vintage Rat II died and I needed a replacement, I was kind of shocked just how inferior the current production Rats are – and the only substantial difference is the op amp. The chip foundry awareness of this problem may have something to do with why certain brands and vintages of multi-sourced chips are favored by audio geeks. May 24, If you want a JRC chip for a project, get a new chip from Steve at Small Bear Electronics who sells them cheap sorry we dont have time to sell chips or small parts.
Gus Member NJ Posts: All had the socket installed, and were cooked 2 output resistor mod. The reason that I even started this thread was to try to get a feel on where the whole TS mojo thing stands.

Put a TL in there and be prepared for an overly bright and brittle sound. Do you already have an account? Mouser s Thanks to anyone with ideas. I wish I could say that it sounded noticably better but the TL that I put in the amp did! I replaced the two output resistors with carbon film resistors I had laying around, and I just order a couple of datasgeet RCP’s for 25 cents a piece.
I attribute the superior tone to the builder datasheeh the box. Aside from basic design, there is another audio issue. Personally, I think it’s the build of the pedal and the sum of all components.
But even all of these years later, the mystique jtc4558dd the ‘ still amazes me. They had nothing in common.
Wonderful chip for many chores, even today. We have all gotten used to that noise, so it sounds better.
Why the stuff in this ost? At low gain settings most opamps sound about the same in the ts circuit.
