And is anyone aware that the TS7 has the “correct” chip and output resistor values? May 23, 3. We have all gotten used to that noise, so it sounds better.
May 24, 8. That’s datssheet o’ them boxes what makes yer amp sound real loud innit? Back to theI think that people are just applying NOS ideas to the chips like they do tubes. You must log in or sign up to reply here. I tested about 25 different chips back in ’99, in a few 9’s, a few 5’s, and a clone.

Personally, I think it’s the build of the pedal and the sum of all components. Several electronics suppliers list the JRC May 24, 5. I put this in the same piles as some of the capacitor, resistor and conductor stuff floating around. Oh, and I should add that it’s unlikely listeners will “get the chips right” in say, blind testing between vintage JRC and new Fairchild.
People are building clones and ditching their ‘real deals’ because they sound better. Yes, my password is: These 3, in particular, sounded really, really good.
Your name or email address: They had nothing in common. Robbie WMay 24, The differences between the TL and the are subtle, but there none the less.
All had the socket installed, and were cooked 2 output resistor mod. 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. There catasheet nothing magical about the “new old stock” JRC that constitutes spending too much money for a “vintage chip”.
Do you already have an account? Saying that the ‘ is the best dual opamp for a TS type pedal is like winning the lottery the very first time you play.

There’s a tremendous difference between being able to detect a difference and being able to specify the cause of the difference. I don’t think we’ll see jrc558 pedal guru doing any sort of semi-scientific chip preference test any time soon though The TL drives things harder and it is tighter and crisper.
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.
There are over 40 different dagasheet op amp chips available. They are still available in isolated caches of parts, although they can sometimes be hard to find.
They were consistently good. Jun 4, The LM sounds great in there and it is a horrible opamp by todays standards. I sent Datashete my TS-9 several years ago and had him replace the chip and beef up some weak spots with no other mods and it came back as he described: If you want “vintage Tube Screamer” then this is the best choice probably.
The old pedal was not superior to the new one in any way, in fact, it was inferior in ways. 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. Sorry to kick over any sacred cows but this is just my opinion based on my experience.
Remove the compensation cap and put a TL in there with the rest of the circuit unmodded and it sounds awful. May 24, 7. Early TS’s have the Ibanez R “trademark” logo which some people seek. May 23, 2. TL my fave The LT was also kinda fatasheet sounding, but not consistently so in the handful of pedals that I tried it in. However, the odds that they’ll hear a difference are very good, and if there’s an audible difference, multiple listeners will have consistent preferences.
The reason a carbon comp resistor sounds “better” than a film resistor is the additional noise it adds to the circuit. But I beleive the old JRC version is the holy grail of some even though the actual chip in some of the originals may be made by others.
Both have the JRC I attribute the datssheet tone to the builder of the box. There are probably 3 that most guitarists would agree sound ‘bad.
Clever marketing can take advantage of this to sell a ten cent amp for ten bucks.
