So... After a very short session of playing, I am VERY impressed. I just grabbed 3 of the Scumback cabs that I thought singtall mentioned (Scumback) and gave them a go.
Richer, deeper, more harmonically rich to my ears. I can see though that I am going to have to finally dig in and start tweaking all the patches. I was spoiled (lazy) and was using a handful of user patches for the last year or so but they lose some luster once the cab is changed to the Epsi.
This whole thing is new to me and I'll have a bunch of questions. I'm thinking I should start a separate thread maybe or is it ok to bother everyone in this one?
Thanks again for all the advice and great info!
