I tested about 25 different chips back in ’99, in a few 9’s, a few 5’s, and a clone.

When you order these, you get parts that are labeled datasheey. 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: Log in or Sign up.

They had nothing in common.

I’m just wondering where things dtasheet stand. What have y’all overheard at the musician’s watercooler discussions? I wish I could say that it sounded noticably better but the TL that I put in the amp did!

Personally, I think it’s the build of the pedal and the sum of all components. The differences between the TL and the are subtle, but there none the less. People are building clones and ditching their ‘real deals’ because they sound better.

May 24, Does true “New Old Stock” matter? I yanked it out and put it in my TS5. You must log in or sign up to reply here. May 24, 8.

I guess I’ll check back in 10 years from now and see how things have changed. TL my fave The LT was also kinda cool sounding, but not consistently so in the handful of pedals that I tried it in. If xatasheet doing this dataxheet a TS 10, short out the 1K resistor leading to pin 3 of the dual opamp as well. However, I think the nature of how silicon works vs.

JRC4558 myths…

That’s one o’ them boxes what makes yer amp sound real loud innit? Both have the JRC Remove the compensation cap and put a TL in there with the rest of the jgc4558 unmodded and it sounds awful. May 24, 9.

Clever marketing can take advantage of this to sell a ten cent amp for ten bucks. On the other hand, “better” and “vintage” aren’t necessarily the same thing, even though they get jumbled together in our sorry little heads.


Even the slew rates, which some believe gives a hint to what makes the ‘ good, were hrc4558 different.

The clone had premium caps as well. Saying that the ‘ is the best dual opamp for a TS type pedal is like winning the lottery the very first time you play. I feel this is the primary reason for the audible differences. 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.

I liked the 3 listed above enough to ‘splurge’ and order about 15 of jrrc4558. I may even run some new tests with more chips, to see if I can find something better than my beloved TL My unscientific conclusion was that the best chip probably has yet to be found.

Do you already have an account? I don’t think I went overboard with the cost on this one.
