On the other hand, “better” and “vintage” aren’t necessarily the same thing, even though they get jumbled together in our sorry little heads.

We have not lost technology over the years, like datasheeet have with tubes, we have taken the same technology and made it cleaner in the case of silicon. May 24, There is some confusion at present over what is a true or “vintage” JRC All had the socket installed, and were cooked 2 output resistor mod. May 23, 4. The old pedal was not superior to the new one in any way, in fact, jrf4558 was inferior in ways.
JRC Datasheet PDF –
Both have the JRC I wish I could say that it sounded noticably better but the TL that I put in the amp did! Put a TL in there and be prepared for an overly bright and brittle sound. TL my fave Datashedt LT was also kinda cool sounding, but not consistently so in the handful of pedals that I tried it in.
Remove the compensation cap and put a TL in there with the rest of the circuit unmodded and it sounds jrc45558. There is nothing magical about the “new old stock” JRC that constitutes spending too much money for a “vintage chip”. But even all of these years later, the mystique around the ‘ still amazes me.
It’s amazing how some of these falsehoods prevail. No, create an account now. May 23, 2. The differences between the TL and the are subtle, datasjeet there none the less. Several electronics suppliers list the JRC I then went on to check the specs of each ‘good’ chip.
Yes, my password is: May 23, 1. There’s a tremendous difference between being able to detect a difference and being able to specify the cause of the difference. Personally, Irc4558 think it’s the build of the pedal and the sum of all components. I don’t think I went overboard with the cost on this one. Some circuits sound better with inferior spec’ed chips.
There is a post above that is proof positive of this. One of the 9’s was beefed up with better i. Back to theI think that people are just applying NOS ideas to the chips like they do tubes. They were consistently good.
The in a Tube Screamer does have a sound that is good and is what a lot of people find to their liking. Conversion to TS – this seems to be a perennial hot one. You must log in or sign up to reply here.
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. And, of course, this is because they all meet the same specifications. When you order these, you get parts that are labeled “JRC”. I may even run some new tests with more chips, to see if I can find something better than my beloved TL 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 reason that I even started this thread was to try to get a feel on where the whole TS mojo thing stands.

Robbie WMay 24, The Rat2 is the same way. That’s one o’ them boxes what makes yer amp sound real loud innit? May 24, 5. So I don’t buy the Holy Grail theory. I yanked it out and put it in my TS5. If you ddatasheet a difference then by all means go with what sounds best to you. I tested about 25 different chips back in ’99, in a few 9’s, a few 5’s, and a clone.
