I put '57 Classics in my Artcore last week and I'm really pleased with the tone. Here's a sloppy little clip of the Classic Plus in the bridge. Just a touch of OD through my Blues Deluxe. (Backing from Narshadda) Narsh Porn on the Bridge
Thanks for the compliments.
Still tweaking the tone, but it's getting closer. Next step is to try some EH tubes in the preamp section. Hopefully it will give the tone a little more edge without getting harsh.
