Some Burr Brown’s or maybe even something discrete. The first line you read in the abstract of a data sheet is “runs on 0. I think the best thing to do before replacing the opamp is to grab some alligator clips and play with the caps and diodes. I replaced the two output resistors with carbon film resistors I had laying around, and I just order a couple of new RCP’s for 25 cents a piece.

And since most opamps have MANY non-audio uses, most foundries are not focused on “our” needs. I definitely want to upgrade to Burr Browns or something quality.

It’s a little relieving to know that some of the opamp chip gurus were willing to let this out of the bag. Several electronics suppliers jrc4558d the JRC Thanks soooo much, I’m hoping the PSU will have the strength to provide the current for the more hefty op amps.

I yanked it out and put it in my TS5. At low gain settings most opamps sound about the same in the ts datasbeet. And is anyone aware that urc4558dd TS7 has the “correct” chip and output resistor values?

June 18, We would be still shopping at Guitar Center if it weren’t for you! Back when my vintage Rat II died and I needed a replacement, I was kind of shocked just how inferior the current production Rats are – and the only substantial difference is the daatasheet amp. There are zillions of other dxtasheet opamps out there that you can try.


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. There are probably 3 that most guitarists would agree sound ‘bad.

Yes, my password is: May 23, 2. 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.

Just search the metas; there’s lots of info on opamp upgrades. I can get close to the sound of an that has the ” sound” I have been told by friends that they all don’t sound alike. So what do these little 8 pin thingies do?

By all reports, the current manufacture JRCD’s sound just as good as the ones current with the manufacture of the original tube screamers. There were zillions of the real “JRC” made when it was current. All of the ‘ variants sounded quite similar and ‘good’.

May 24, 5.

It’s descended from the single and the dual. Milkmansound Milkmansound on Myspace.

Do you already have an account? It also looks like most of the feedback loops are pF. What’s the difference between all the NE’s? I am going to print out the schem and go over it this weekend and make some recommendations then. When you order these, you get parts that are labeled “JRC”. Here’s the input module, http: 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, what can it hurt?


People are building clones and ditching their ‘real deals’ because they sound better.

If they are starved, the chips meet all published specs and give nice low power consumption, but garble the fine detail in good audio. The reason a carbon comp resistor sounds “better” than a film resistor is the additional noise it adds to the circuit.

The ts stuff is kind of based on the opamp used in the stock circuit. I started researching TS’s quite a long time ago. 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. Clever marketing can take advantage of this to sell a ten cent amp for ten bucks.

The LM sounds great in there and it is a horrible opamp by todays standards.

A need a realy good player I know a few with a good amp and guitar to hear what it does. What do ‘s sound like? There is one part that has no brand markings and gives just jrc4558ddd right grit to smooth with signal level in the magic s.

That’s one o’ them boxes what makes yer amp sound real loud innit? The Rat2 is the same ddatasheet. Those are widely used in more contemporary equipment such as Mackie, Samson, and Behringer.

June 19, We have all gotten used to that noise, so it sounds better.
