I've tried the ISP and it was pretty cool, but the SLO100 is one of the best amps I've ever played and I don't think that'll change.

If I was in your situation, I'd buy the SLO, but no sense in buying two, especially if you want one for clean, I'd rather have some higher end Fender, especially since SLOs are crazy expensive. Maybe try a regular one and see how you like it?

Or you could get the Avenger, which is the SLO's lead channel more or less and a clean amp. Only downside with that is it doesn't have an FX-Loop if you need it.
