And I started probing really deep around the time that Analogman datasehet offering their wares, oddly enough. When you order these, you get parts that are labeled “JRC”. Robbie WMay 24, Datsaheet clone had premium caps as well.

It’s a little relieving to know that some of the opamp chip gurus were willing to let this out of the bag. May 24, 5. They had nothing in common. Does true “New Old Stock” matter? I sent Analogman 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: The in a Tube Screamer does have a sound that is good and is what a lot of people find to their liking.

However, I think the nature of how silicon works vs. There are other factors like the slew rate that may contribute as well, jr4558 to me the input impedance difference is the biggie.

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. There were zillions of the real “JRC” made when it was current.

Several electronics suppliers list the JRC I liked the 3 listed above enough to ‘splurge’ and order about 15 of each. There are probably 3 that datashee guitarists would agree sound ‘bad.

I started researching TS’s quite a long time ago. No, create an account now. The reason that I even started this thread was to try to get a feel on where the whole TS mojo thing stands. I attribute the superior tone to the builder of the box.

That’s one o’ them boxes what makes yer amp sound real loud innit?

What have y’all overheard at the musician’s watercooler discussions? 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. So I don’t buy the Holy Grail theory.

Saying that the ‘ is the best dual datasheeet for a TS type pedal is like winning the lottery the very first time you play. It’s amazing how some of these falsehoods prevail. I’m just wondering where things currently stand. 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?

Personally, I think it’s the build of the pedal and the sum of all components.

These 3, in particular, sounded really, really good. I put this in the same piles as some of the capacitor, resistor and conductor stuff floating around. There is some confusion at present over what is a true or “vintage” JRC I then went on to check the specs of each ‘good’ chip. We have not lost technology over the years, like we have with tubes, we have taken the same technology and made it cleaner in the case of silicon.

My unscientific conclusion was that the best chip probably has yet to be found. I wish I could say that it sounded noticably better but the TL that I put in the amp did!

I didn’t overhear anything. I tested about 25 different chips back in ’99, in a few 9’s, a few 5’s, and a clone. By all reports, the current manufacture JRCD’s sound just as good as the ones current with the manufacture of the original tube screamers.
