The TL drives things harder and it is tighter and crisper.
Both have the JRC May 24, They were consistently good. I think the high end stereo guys, in particular, have been suseptable to this sort of pseudo-scientific clap-trap. I dataxheet I’ll check back in 10 years from now and see how things have changed.
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 differences between the TL and the are subtle, but datashheet none the less. I’m just curious, because most pedal experts seem to concur that both old and current production chips from different parts of Asia all tend to sound consistently the same.
Datashest just wondering where things currently stand. People are building clones and ditching their ‘real deals’ because they sound better. No, create an account now. One of the 9’s was beefed up with better i.
Do you already have an account?
This is where the rec. If you want “vintage Tube Screamer” then this is the best choice probably. It’s a little relieving to know that some of the opamp chip gurus were willing to let this out of the bag.
May 23, 1. Jun 4, Robbie WMay 24, I then went on to check the specs of each ‘good’ chip. What have y’all overheard at the musician’s watercooler discussions?

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? In addition, the JRCD was used in tons of Japanese audio equipment at about the same time, so a junky cheap Japanese stereo or clock radio could have several hidden inside it.
Back to theI think that people are just applying NOS ideas to the chips like they do tubes. There were zillions of the real “JRC” made when it was current. If you’re doing this to a TS 10, short out the 1K resistor leading to pin 3 of the dual opamp as well. If you hear a difference then by all means go with what sounds best to you. Does true “New Old Stock” matter? I tested about 25 different chips back in ’99, in a few 9’s, a few 5’s, and a clone. And is anyone aware that the TS7 has the “correct” chip and output resistor values?
And, of course, this is because they all meet the same specifications. Oh, and I jrc558 add that it’s unlikely listeners will “get the chips right” in say, blind testing between vintage JRC and new Fairchild.
All had the socket installed, and were cooked 2 output resistor mod. It’s amazing how some of these falsehoods prevail. I will go as far jrc45558 say ALL ‘s sound so similar I doubt anyone could hear a difference in a blindfold test.
May 24, 9. 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. As far as ‘s in jrc4585 I will say this.
May 23, 2. I wish I could say that it sounded noticably better but the TL that I put in the amp did! May 24, 8. Your name or email address: I know I read something recently about the that even when ratasheet TS was in original production, there was no single vendor. The TL has a lot higher input impedance extremely higher actually. Are the misinformed still spending 30 bucks or more for a “NOS” chip, and 2 “brown sound” resistors? I attribute the superior tone to the builder of the box.
These 3, in particular, sounded really, really good.

May 24, 6. May 23, 4. We have all gotten used to that noise, so it sounds better. You must log in or sign up to reply here. Personally, I think it’s the build of the pedal and the sum of all components. I started researching TS’s quite a long time ago. Log in or Sign up.
