Thanks a lot to all of you who share your time and knowledge to those of us who are just starting to understand electronics.

Ben HarmlessJun 4, There are over 40 different dual op amp chips available. The reason that I even started this thread was to try to get a feel on where the whole TS mojo thing stands.

They are still available in isolated caches of parts, although they can sometimes be hard to find. Even in an 8-in board, the difference between TL and power demand will make a big difference in power supply size and cost.

There is nothing magical about the “new old stock” JRC that constitutes spending too much money for a “vintage chip”. 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.

November 29, June 18, The clone had premium caps as well. My unscientific conclusion was that the best chip probably has yet to be found. I tested about 25 different chips back in ’99, in a few 9’s, a few 5’s, and a clone. I started researching TS’s quite a long time ago.

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. On the other hand, I also think we all at least I have personally tried some of the products on the idea of “if I can afford it, irc4558dd can it hurt? I believe I know why.


The ts stuff is kind of based on the opamp used in the stock circuit. I may even run some new tests with more chips, to see if I can find something better than my beloved TL We would be datasueet shopping at Guitar Center if it weren’t for you!

I didn’t overhear anything. The Rat2 is the same way. Milkmansound Milkmansound on Myspace. When you order these, you get parts that are labeled “JRC”. Both have the JRC And, of course, this is because they all meet the same specifications. I then went on to check the specs of each ‘good’ chip. You must log in or sign up to reply here.

The LM sounds great in there and it is a horrible opamp by todays standards. It was all right in its day but it’s not a very good opamp by current standards. That’s one o’ them boxes what makes yer amp sound real loud innit? It also looks like most of the feedback loops are datasehet. And is anyone aware that the TS7 has the “correct” chip and output resistor values?

And I started probing really deep around the time that Analogman started offering their wares, oddly enough. The in a Tube Screamer does have a sound that is good and is what a lot of people find to their liking. I imagine they are like tubes in that they can do a variety of things, and that you can swap different ICs to get a different sound, like swapping a 12AX7 for a 12AT7.

NJM4558DD / JRC4558DD Original Japan, DIP8

I just remember someone once telling me to get rid of those s. Some Burr Brown’s or maybe even something discrete. I just don’t want to blow up my PSU. Saying that the ‘ is the best dual opamp for a TS type pedal is like winning the lottery dztasheet very first time you play. Just search the metas; there’s lots of info on opamp upgrades.


All had the socket installed, and were cooked 2 output resistor jtc4558dd. Remove the compensation cap and put a TL in there with the rest of the circuit unmodded and it sounds awful. No, create an account now. I’ll look up some Dual Op Amps. May 23, 1.

NJMDD / JRCDD Original Japan, DIP8 – Retroamplis

I have a whole bunch that I have been collecting out of old Japanese radios from the 80’s that I scrapped out. I asked about this console before http: You’ll find it on zillions of soundcards, mixers, etc. If they are starved, the chips meet all published specs and give nice low power consumption, but garble the fine detail in good audio.

I don’t think I went overboard with the cost on this one. However, I think the nature of how silicon works vs. 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 have not been able to copy it and I doubt others have, but how can anyone tell unless they have a real to check it against.

Those chips will be a serious upgrade, but few dafasheet get excited about them. Some circuits sound better with inferior spec’ed chips. As far as ‘s in general I will say this.
