4558P Datasheet

I have another clone of the same circuit that I paid significantly less datasheeet and it shows. I don’t think I went overboard with the cost on this one.

The reason a carbon comp resistor sounds “better” than a film resistor is the additional noise it adds to the circuit. I think the high end stereo guys, in particular, have been suseptable to this sort of pseudo-scientific clap-trap.

Clever marketing can take advantage of this to sell a ten cent amp for ten bucks. I tested about 25 different chips back in ’99, in a few 9’s, a few 5’s, and a clone.

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? Datashete all reports, the current manufacture JRCD’s sound just as good as the ones current with the manufacture of the original tube screamers. Your name or email address: And is anyone aware that the TS7 has the “correct” chip and output resistor values? These 3, in particular, sounded really, really good. They had nothing in common.

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. As far as ‘s in general I will say this.

dtasheet There are over 40 different dual op amp chips available. When you order these, you get parts that are labeled “JRC”. There are probably 3 that most guitarists would agree sound ‘bad. The datashset a Tube Screamer does have a sound that is good and is what a lot of people find to their liking. I will go as far to say ALL ‘s sound so similar I doubt anyone could hear a difference in a blindfold test. May 23, 3.

Do you already have an account? TL my fave The LT was also kinda datashret sounding, but not consistently so in the handful of pedals that I tried it in. Both have the JRC And I started probing really deep around the time that Analogman started offering their wares, oddly enough. 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.

May 24, 7. The differences between the TL and the are subtle, but there none the less. I may even run some 45588p tests with more chips, to see if I can find something better than my beloved TL No, create an account now. All of the ‘ variants sounded quite similar and ‘good’.

Personally, I think it’s the build of the pedal and the sum of all components. Conversion to TS – this seems to be a perennial hot one. Are the misinformed still spending 30 bucks or more for a “NOS” chip, and 2 “brown sound” resistors? The thing is, op amps are actually fairly complicated devices internally, and can have widely varying behaviors for slew rate, noise, etc, while being “rated” the same in identical conditions.

That’s one o’ them boxes what makes yer amp sound real loud innit?

The Rat2 is the same way.
