Pinout can vary by different types so allways check from datasheet These are the pins in test circuits Welcome to our site! Input sensitivity for full power for a start would help May 24, 5.

Yes, my password is: It’s amazing how some of these falsehoods prevail.

This IC has been used in guitar and bass amps. They are still available in isolated caches of parts, although they can sometimes be hard to find. There is a post above that is proof positive of datawheet. May 24, 9. I will go as far to say ALL ‘s sound so similar I doubt anyone could hear a difference in a blindfold test.

First check IC type and pinout from datasheet. May 24, nrc May 24, 8. I think the high end stereo guys, in particular, have been suseptable to this sort of pseudo-scientific clap-trap. I feel this is the primary reason for the audible differences.

Synthesized tuning, Part 2: The in a Tube Screamer does have a sound that is good and is what a lot of people find to their liking.

Clever marketing can take advantage of this to sell a ten cent amp for ten bucks. Dec 242: However, I think the nature of how silicon works vs.

On the other hand, “better” and “vintage” aren’t necessarily the same thing, even though they get jumbled together in our sorry little heads. What signal source are you feeding into the preamp, this along with the power amp sensitivity will set the over all gain of the preamp section One dataheet the 9’s was beefed up with better i. And, of course, this is because they all meet the same specifications. There are over 40 different dual op amp chips available.

I have another clone of the same circuit that I paid significantly less for and it shows. People are building clones and ditching their ‘real deals’ because they sound better. So I don’t buy the Holy Grail theory.

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.
