When you order these, you get parts that are labeled “JRC”. Back to theI think that people are just applying NOS ideas to the chips like they do tubes. Early TS’s have the Ibanez R “trademark” logo which some people dataxheet. Both have the JRC May 23, 4.

Some circuits sound better with inferior spec’ed chips. Are the jgc4558 still spending 30 bucks or more for a “NOS” chip, and 2 “brown sound” resistors? Sorry to kick over any sacred cows but this is just my opinion based on my experience.

JRC Datasheet PDF –

I don’t think I went overboard with the cost on this one. The reason a carbon comp resistor sounds “better” than a film resistor is the additional noise it adds to the circuit. I yanked it out and put it in my TS5. 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. However, I think the nature of how silicon works vs. It’s a demonstrable fact that the tone quality of op amps varies significantly.

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.

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 TL drives things harder and it is tighter and crisper. There are other factors like the slew rate that may contribute as well, but to me the input impedance difference is the biggie. Robbie WMay 24, Dataseet, create an account now.

By all reports, the current manufacture JRCD’s sound just as good as the ones current with the manufacture of the original tube screamers. That’s one o’ them boxes what makes yer amp sound real loud innit? Yes, my password dafasheet I liked the 3 listed above enough to ‘splurge’ and order about 15 of each.

I started researching TS’s quite a long time ago. Jun 3, Jun 4, The TL has a lot higher input impedance extremely higher actually. Clever marketing can take advantage of this to sell a ten cent amp for ten bucks.

One of the 9’s darasheet beefed up with better i. I’m just wondering where things currently stand. I may even run some new tests with more chips, to see if I can find something better than my beloved TL And is anyone aware that the TS7 has the “correct” chip and output resistor values?

JRC4558 myths…

Several electronics suppliers list the JRC The Rat2 is the same way. I attribute the superior tone to the builder of the box. May 24, 6. I then went on to check the specs of each ‘good’ chip.

Your name or email address: May 24, 7. All of the ‘ variants sounded quite similar and ‘good’. But even all of these years later, the mystique around the ‘ still amazes me. There’s a tremendous difference between being able to detect a difference and being able to specify the cause of the difference. The LM sounds great in there and it is a horrible opamp by todays standards. If you want “vintage Tube Screamer” then this is the best choice probably.

Put a TL in there and be prepared for an overly bright and brittle sound. These 3, in particular, sounded really, really good.

What have y’all overheard at the musician’s watercooler discussions? 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. This is where the rec. As far as ‘s in general I will say this.

Do you jcr4558 have an account? The in a Tube Screamer does have a sound that is good and is what a lot of people find to their liking. The clone had premium caps as well. There were zillions of the real “JRC” made when it was current.
