JRC myths | Telecaster Guitar Forum

Several electronics suppliers list the JRC Even in an 8-in board, the difference between TL and power demand will make a big difference in power supply size and cost. By all reports, these sound as good as the original.

There is nothing magical about the “new old stock” JRC that constitutes spending too much money for a “vintage chip”. Jrc4558de put this in the same piles as some of the capacitor, resistor and conductor stuff floating around.

Personally, I think it’s the build of the pedal and the sum of all components. They had nothing in common. Mouser s Thanks to anyone with ideas. October 05, Any input anyone can give please chime in. Its not a big difference and it only realy shows with a good player and good equipment IMO.

Sometimes I think I’m dyslexic. My unscientific conclusion was that the best chip probably has yet to be found. 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 jcr4558dd amp. It wasn’t even made for that. It’s amazing how some of these falsehoods prevail.

JRC4558 myths…

It’s descended from the single and the dual. All had the socket installed, and were cooked 2 output resistor mod. One of the 9’s was beefed up with better i.

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. I can get close to the sound of an that has the ” sound” I jtc4558dd been told by friends that they all don’t sound alike.

I don’t think we’ll see a pedal datashee doing any sort of semi-scientific chip preference test any time soon though The LM sounds great in there and it is a horrible opamp by todays standards. There were zillions of the real “JRC” made when it was current.

I liked the 3 listed above enough to ‘splurge’ and order about 15 of each.

You must log in or sign up to reply here. I just remember someone once telling me to get rid of those s. What do you guys think about the OPA ? I then went on to check the specs of each ‘good’ chip. May 23, 1. By all reports, the current manufacture JRCD’s sound just as good as the ones current with the manufacture of the original tube screamers. Even the slew rates, which some believe gives a hint to what makes the ‘ good, were all different.


Yes on what Paul said. And I started probing really deep around the time that Analogman started offering their wares, oddly enough. 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. No, create an account now. There are probably 3 that most guitarists would agree sound ‘bad.

As far as ‘s in general I will say this. Early TS’s have the Ibanez R “trademark” logo which some people seek. There are direct upgrades from JRC, i.

CJ Member California Posts: Theaside from being dual, pushed the speed of the core, to the point that it was considered good enough for a lot of audio work. Why the stuff in this ost? May 23, 4. 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.
