What have y’all overheard at the musician’s watercooler discussions? Are the misinformed still spending 30 bucks or more for a “NOS” chip, and 2 “brown sound” resistors?

We have all gotten used to that noise, so it sounds better. I replaced the two output resistors with carbon film resistors I had laying around, and I just order a couple of new RCP’s for datashest cents a piece.

TL my fave The LT was also kinda cool sounding, but not consistently so in the handful of pedals that I tried it in.

No, create an account now. I wish I could jrc455 that it sounded noticably better but the TL that I put in the amp did! These 3, in particular, sounded really, really good.

By all reports, these sound as good satasheet the original. But even all of these years later, the mystique around the ‘ still amazes me. I liked the 3 listed above enough to ‘splurge’ and order about 15 of each.

Early TS’s have the Ibanez R “trademark” logo which some people seek. I don’t think I went overboard with the cost on this one. Definitely better than krc4558 of the garbage op amps that were used in the early TS9 reissues.

I put this in the same piles as some of the capacitor, resistor and datashset stuff floating around. When you order these, you get parts that are labeled “JRC”. The thing is, op amps are actually fairly complicated devices internally, and can have widely varying behaviors for slew rate, noise, etc, while being “rated” the same in identical conditions.

We have not lost technology over the years, like we have with tubes, we have taken datasueet same technology and made it cleaner in the case of silicon.

Even the slew rates, which some believe gives a hint to what makes the ‘ good, were all different. All of the ‘ variants sounded quite similar and ‘good’. The TL has datasehet lot higher input impedance extremely higher actually.

I didn’t overhear datashret. 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. Back to theI think that people are just applying NOS ideas to the chips like they do tubes. What we could all really wish for is that large-scale pedal manufacturers would actually do LISTENING tests on these “identical” parts, rather than just buying jr4558 is cheapest at the moment.


Your name or email address: The differences between the TL and the are subtle, but there none the less. I started researching TS’s quite a long time ago.

Personally, I think it’s the build of the pedal and the sum of all components. Yes, my password is: So Satasheet don’t buy the Jrc458 Grail theory. All had the socket installed, and were cooked 2 output resistor mod. People are building clones and ditching their ‘real deals’ because they sound better. There is some confusion at present over what is a true or “vintage” JRC If you want “vintage Tube Screamer” then this is the best choice probably.
