Overdrive-II changes iss 1 to iss 2 ?

Post by Noiseconformist »

Hi,
what are the differences between issue 2 and issue 1 of the Overdrive-II module?
Anything worth modding?
Thanks, Michael.

I think the only differences are small layout changes to suit the newer dotcom power header format. It's also a different board manufacturer.

I now recommend that U7 be a OPA2134. The original schematics show a TL072, but with very large input signal levels this can be pushed into phase reversal which doesn't sound that nice. The OPA2134 is immune to such poor behaviour.

Thanks for your quick reply, Tony!
Would be an easy swap to try (besides that I don't have one in the drawer).
Michael.
