All of the ‘ variants sounded quite similar and ‘good’. All had the socket installed, and were cooked 2 output resistor mod.

As far as ‘s in general I will say this. The TL has a lot higher input impedance extremely higher actually. Jun 3, May 23, 3. I may even run some new tests with more chips, to see if I can find something better than my beloved TL Put a TL in there and be prepared for an overly bright and brittle sound.

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? I’m just wondering where things currently stand.

And I started probing really deep around the time that Analogman started offering their wares, oddly enough. Personally, I think it’s the build datasgeet the pedal and the sum of all components.
