There are direct upgrades from JRC, i. 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 yanked it out and put it in my TS5. 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.
If you want “vintage Tube Daasheet then this is the best choice probably. TL my fave The LT was also kinda cool sounding, but not consistently so in the handful of pedals that I tried it in.
It also looks like most of the feedback loops are pF. Unless you want to build a Tube Screamer pedal, that is. So I don’t buy the Holy Grail theory. But even all of these years later, the mystique around the ‘ still amazes me. The clone had premium caps as well. We would be still shopping at Guitar Center if it weren’t for you! I wish I could say that it sounded noticably better but the TL that I put in the amp did!
Do you already have an account? I have a whole bunch that I have been collecting out of old Japanese radios from the 80’s that I scrapped out. Log in or Sign up. CJ Member California Posts: Some circuits sound better with inferior spec’ed chips. I’ll look up some Dual Op Amps. The reason I ask, besides understanding, is that each module on my console has about several dx, I don’t have a schematic, but just by glancing at the PCB it looks like there are 3 on the EQ, one with the aux sends, and one by the bus assignments.
I feel this is the primary reason for the audible differences.
Does true “New Old Stock” matter? Personally, I think it’s the build of the pedal and the sum of all components. They are still available in isolated caches of parts, although they can sometimes be hard to find.
Its not a big difference and it only realy shows with a good player and good dataaheet IMO. I just remember someone once telling me to get rid of those s. Some ICs when overdriven sound more musical than others.

The NJM is virtually everywhere these days. Back to theI jrrc4558dd that people are just applying NOS ideas to the chips like they do tubes. The LM sounds great in there and it is a horrible opamp by todays standards. Robbie WMay 24, Even in an 8-in board, the difference between TL and power demand will make a big difference in power supply size and cost.
May 23, 4. Why the stuff in this ost? Those chips will be a serious upgrade, but few people get excited about them. The TL drives things harder and it is tighter and crisper. One of the 9’s was beefed up with better i.

What do you guys think about the OPA ? 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 op amp. On the other hand, “better” and “vintage” aren’t necessarily the same thing, even though they get jumbled together in our sorry jrc4558cd heads. What’s the difference between dataaheet the NE’s?

October 05, However, I think the nature of how silicon works vs. Yes on what Paul said.
I then went on to check the specs of each ‘good’ chip. Started by ebartlet The Lab.
