It’s a little relieving to know that some of the opamp chip gurus were willing to let this out of the bag. I feel this is the primary reason for the audible differences.
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? We have not lost technology over the years, like we have with tubes, we have taken the same technology and made it cleaner in the case of silicon. I guess I’ll check back in 10 years from now and 4558 how things have changed.
I’m just wondering where things currently stand. Your name or email address: I may even run some new tests with more chips, to see if I can find something better than my beloved TL The differences between the TL and the are subtle, but there none the less. The Rat2 is the same way. There’s a tremendous difference between being datasheeg to detect a difference and being able to specify the cause of the difference.
dattasheet Ben HarmlessJun 4, Are the misinformed still spending 30 bucks or more for a “NOS” chip, and 2 “brown sound” resistors? And is anyone aware that the TS7 has the “correct” chip and output resistor values? And, of course, this is because they all meet the same specifications. I attribute the superior tone to the builder of the box.
Oh, and I should add that it’s unlikely listeners will “get the chips right” in say, blind testing between vintage JRC and new Fairchild. I started researching TS’s quite a long time ago. May 24, 5. The LM sounds great in there and it is a horrible opamp by todays standards.
It’s amazing how some of these falsehoods prevail. 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. May 23, 1. I then went on to check the specs of each ‘good’ 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. This is where the rec. The old pedal was not superior to the new one in any way, in fact, it was inferior in ways. So I don’t buy the Holy Grail theory. Log in or Sign up.
May 24, 7. They were consistently good. Back to the4558pp think that people are just applying NOS ideas to the chips like they do tubes.
Jun 3, Some circuits sound better with inferior spec’ed chips. There is nothing magical about the “new old stock” JRC that constitutes spending too much money for a “vintage chip”.
May 23, 4. The reason a carbon comp resistor sounds “better” than a film resistor is the additional noise it adds to the circuit.
Robbie WMay 24, If you hear a difference then by all means go with what sounds best to you. What have y’all overheard at the musician’s watercooler discussions? There are probably 3 that most guitarists would agree sound ‘bad.
If you want “vintage Tube Screamer” 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. People are building clones and ditching their ‘real deals’ because they sound better. There are other factors like the slew rate that may contribute as well, but to me the input impedance difference is the biggie.
One of the 9’s was beefed up with better i. I will go as far to say ALL ‘s sound so similar I doubt anyone could hear a difference in a blindfold test. Even the slew rates, which some believe gives a hint to what makes the ‘ good, were all different. The Datawheet drives things harder and it is tighter and crisper. I liked the 3 listed above enough to ‘splurge’ and order about 15 of each.
That’s one o’ them boxes what makes yer amp sound real loud innit? I think the high end stereo guys, in particular, have been suseptable to this sort of pseudo-scientific clap-trap.
There are millions of these vintage chips out there in old 70’s electronics junk. May 24, 8. The in a Tube Screamer does have a dagasheet that is good and is what a lot of people find to their liking. When you order these, you get parts that are labeled “JRC”.
On the other hand, “better” and “vintage” aren’t necessarily the same thing, even though they get jumbled together in our sorry little heads.
