Q4 Ken Fox re:N112 mod

Jonathan Shacklock · From: London, UK

Some while ago I bought a Nash 112 mod kit (thanks again Ken, excellent service). There was a very noticeable smoothing out of the amp's tone and in particular the reverb seemed deeper and richer. The overall effect is perhaps too mellow for my taste, and my guitar, I still haven't entirely made up my mind.

Today I came across the original N112 chips and I was wondering if mix and matching the old and new chips would produce interesting results. In particular I'd like to hear the original chips with the modified reverb, however I don't know if one of the five chips maps directly to the reverb in this way (and if so which one). Is it all or nothing? Or does each chip smooth out the signal path in a cumulative effect?

U1b 2nd gain stage after pre eq return jack)
U2a 3rd gain stage after high and low eq

U3 mid shift control
U4b 5th gain stage and mid control

Thanks Ken, I'll give it a go. Smile
