I attribute the superior tone to the builder of the box. I may even run some new tests with more chips, to see if I can find something better than my beloved TL By all reports, the current manufacture JRCD’s sound just as good as the ones current with the manufacture of the original tube screamers.

And I started probing really deep around the time that Analogman started offering their wares, oddly enough. It’s amazing how some of these falsehoods prevail. They are still available in isolated caches of parts, although they can sometimes be hard to find. There are over 40 different dual op amp chips available.

May 23, 1. Robbie WMay 24, Your name or email address: Ben HarmlessJun 4, There were zillions of the real “JRC” made when it was current. May 23, 2. 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.


The in a Tube Screamer does have a sound that is good and is what a lot of people find to their liking. I tested about 25 different chips back in ’99, in a few 9’s, dahasheet few 5’s, and a clone.

And, of course, this is because they all meet the same daatsheet. Log in or Sign up.

Jun 3, By all reports, these sound as good as the original. The old pedal was not superior to the new one in any way, in fact, it was jrc45588 in ways. Remove the compensation cap and put a TL in there with the rest of datqsheet circuit unmodded and it sounds awful.

So I don’t buy the Holy Grail theory. That’s one o’ them boxes what makes yer amp sound real loud innit? Back when dahasheet 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. I guess I’ll check back in 10 years from now and see how things have changed.

The differences between the TL and the are subtle, but there none the less. May 23, 4.

They had nothing in common. Even the slew rates, which some believe gives a hint to what makes the ‘ good, were all different. May 24, 9.

JRC4558 myths…

And is anyone aware that the TS7 has the “correct” chip and output resistor values? Definitely better than some of the garbage op amps that were used in the early TS9 datashert. Yes, my password is: 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 datasneet Do you already have an account? I know I read dahasheet recently about the that even when the TS was in original production, there was no single vendor.


The Rat2 is the same way. The TL has a lot higher input impedance extremely higher actually. But even all of these years later, the mystique around the ‘ still amazes me. No, create an account now.

JRC4558 Datasheet

There are probably 3 that most guitarists would agree sound ‘bad. These 3, in particular, sounded really, really good. If you hear a difference then by all means go with what sounds best to you. All had the socket installed, and were cooked 2 output resistor mod. I’m just wondering where things currently stand.

This is where the rec. If you want “vintage Tube Screamer” then this is the best choice probably. TL my fave The LT was also kinda cool sounding, but not jrf4558 so in the handful of pedals that I tried it in. I yanked it out and put it in my TS5. There is nothing magical about the “new old stock” JRC that constitutes spending too much money for a “vintage chip”.
