We have all gotten jgc4558 to that noise, so it sounds better. If you want “vintage Tube Screamer” then this is the best choice probably. May 23, 3. I sent Analogman my TS-9 several years ago and had him replace the chip and beef up some weak spots with no other mods and it came back as he described: If you hear a difference then by all means go with what sounds best to you.

The TL drives things harder and it is tighter and crisper. Your name or email address: Remove the compensation cap and put a TL in there with the rest of the circuit unmodded and it sounds awful.

I attribute the superior tone to the builder of the box. But even all of these years later, the mystique around the ‘ still amazes me.

There are probably 3 that most guitarists would agree sound ‘bad. When you order these, you get parts that are labeled “JRC”. The LM sounds great in there and it is a horrible opamp by todays standards.

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.

Dztasheet, of course, this is because they all meet the same specifications. The reason that I even started this thread was to try to get a feel datashete where the whole TS mojo thing stands. There are other factors like the slew rate that may contribute as well, but to me the input impedance difference is the biggie. I know I read something recently about the that even when the TS was in original production, there was no single vendor.

May 23, 2. I may even run some new tests with more chips, to see if I can find something better than my beloved TL Saying that the ‘ is the best dual opamp for a TS type pedal is like winning the lottery the very first time you play.

What have y’all overheard at the musician’s watercooler discussions? The clone had premium caps as well. They had nothing in common. As far as ‘s in general I will say this.

And is anyone aware that the TS7 has the “correct” chip and output resistor values? One of the 9’s was beefed up with better i.
