I googled and couldn’t find much except people selling them. One of the 9’s was beefed up with better i. What we could all really wish for is datasheet large-scale pedal manufacturers would actually do LISTENING tests on these “identical” parts, rather than just buying whatever is cheapest at the moment.

I started researching TS’s quite a long time ago. There are other factors like the slew rate that may contribute as well, but to me the input impedance difference is the biggie. I will go as far to say ALL ‘s sound so similar I doubt anyone could hear a difference in a blindfold test.

Nachoman, It looks like we’ve forgotten about you, but that is not the case. And, of course, this is because they all meet the same specifications. Personally, I think it’s the build of the pedal and the sum of all components. Jun 3, May 23, 2. Most chip makers think low power consumption is a priority.

JRC4558 myths…

Aside from basic design, there is another audio issue. Sorry to kick over any sacred cows but this is just my opinion based on my experience. May 24, 6. June 19, There are probably 3 that most guitarists would agree sound ‘bad. The can be criticized for not being fast enough for clean high-level audio.


And “minor” chip redesigns that do not affect the “normal” performance can make significant difference when you go outside the normal range. I didn’t overhear anything.

Do any of you guys live in the LA area and wouldn’t mind looking over my console so I don’t blow it up? I tested about 25 different chips back in ’99, in a few 9’s, a few jrc4558dv, and a clone.

Mouser s Thanks to anyone with ideas. There is a post above that is proof positive of this. There were zillions of the real “JRC” made when it was current. There are zillions of other dual opamps out there that you can try.

I’m just wondering where things currently stand. Both have the JRC Milkmansound Milkmansound on Myspace.

Yes, fatasheet password is: I have a whole bunch that I have been collecting out of old Japanese radios from the 80’s that I scrapped out. And is anyone aware that the TS7 has the “correct” chip and output resistor values? The chip foundry awareness of this problem may have something to do with why certain brands and vintages of multi-sourced chips are favored by audio geeks.

There is one part that has no brand markings and gives just the right grit to smooth with signal level in the magic s.

I am going to print out the schem and go over it this weekend and make some recommendations then. 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. A need a realy good player I know a few with a good amp and guitar to hear what it does.


November 29, The is a standard dual opamp. It’s descended from the single and the dual. Remove the compensation cap and put a TL in there with the rest of the circuit unmodded and it sounds awful. I figure there is something out there that I can swap these out for to give me a sweeter sounding console. Like I said I have modded a number of TSs and own 7 TS and ts type effects, all setup different chips, caps, gain I let my friends try them not knowing what the mods are so they can pick the mod they want not one of them is the same as a real TS,one is as close as I can get so far.

It’s amazing how some of these falsehoods datasheft. If you want “vintage Tube Screamer” then this is the best choice probably. Jun 4, Here’s the input module, http: Rossi Member Germany Posts: I then went on to check the specs of each ‘good’ chip.

If you want a JRC chip for a project, get a new chip from Steve at Small Bear Electronics who sells them cheap sorry we dont have time to sell chips or small parts.

It’s a fairly old design and not really good for audio.

They are still available in isolated caches of parts, although they can sometimes be hard to find. I certainly don’t care about this, jrc4558df other people do.
