Clever marketing can take advantage of jrc458dd to sell a ten cent amp for ten bucks. 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. In addition, the JRCD was used in tons of Japanese audio equipment at about the same time, so a junky cheap Japanese stereo or clock radio could have several hidden inside it.
I figure the is part of jrc4558sd amplifier. If they are starved, the chips meet all published specs and give nice low power consumption, but garble the fine detail in good audio. If the s are JRC or TI you might want to try the circuit at high gain settings to see if maybe they might add something nice to the sound.
They had nothing in common. Some Burr Brown’s or maybe even something discrete. All of the ‘ variants sounded quite similar and ‘good’.
You’ll find it on zillions of soundcards, mixers, etc. I’m just curious, because most pedal experts seem to concur that both nrc4558dd and current production chips from different parts of Asia all tend to sound consistently the same. I have a whole bunch that I datashdet been collecting out of old Japanese radios from the 80’s that I scrapped out.
October 05, Are the misinformed still spending 30 bucks or more for a “NOS” chip, and 2 “brown sound” resistors? Back to theI think that people are just applying NOS ideas to the chips like they do tubes.
Gus Member NJ Posts: Log in or Jrd4558dd up. The old pedal was not superior to the new one in any way, in fact, it was inferior in ways. These 3, in particular, sounded really, really good.
May 23, 2. Why the stuff in this ost? I datashete and couldn’t find much except people selling them. It is a good beginners and sometimes experienced geek’s referance that is out of print from Radio Shack. If you hear a difference then by all means go with what sounds best to you. And is anyone aware that the TS7 has the “correct” chip and output resistor values?

I attribute the superior tone to the builder of jrc4558dd box. I don’t think I went overboard with the cost on this one. The LM sounds great in there and it is a horrible opamp by todays standards. I’ll look up some Dual Op Amps.
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. Saying that the ‘ is the best dual opamp for a TS type pedal is like dagasheet the lottery the very first time you play. There is a post above that is proof positive of this.
Its not a big difference and it only realy shows with a good player and good equipment IMO. I figure there is datazheet out there that I can swap these out for to give me a sweeter sounding console. They were consistently good. Put a TL in there and be prepared for an overly bright and brittle sound.
I will jrc45558dd scan all the kid’s projects in the back, but will put up the main info. Rossi Member Germany Posts: It’s a little relieving to know that some of the opamp chip gurus were willing to let this out of the bag. And, of course, this is because they all meet the same specifications.
There is one part that has no brand markings and gives just jrc458dd right grit to smooth with signal level in the magic s. Those are widely used in more contemporary equipment such as Mackie, Samson, and Behringer.
May 24, It has a fairly larger transformer so hopefully I’m in luck. Back when my vintage Rat II died and I needed a replacement, I was kind of shocked dtaasheet how inferior the current production Rats are – and the only substantial difference is the op amp.

What we could all really wish for is that large-scale pedal jrc4558ds would actually do LISTENING tests on these “identical” parts, rather than just buying whatever is cheapest at the moment. The reason that I even started this thread was to try to get a feel on where the whole TS mojo thing stands. There were zillions of the real “JRC” made when it was current.
Early TS’s have the Ibanez R “trademark” logo which some people seek. CJ Member California Posts: There are direct upgrades from JRC, i.
