Why not a multi-effects board? I have the Digitech GNX4 and it can produce any sound you're looking for, as well as recording direct via USB. If it's just for practicing, there's a headphone jack for those purposes. I couldn't live without mine, and the recording quality is great. I bought mine for $469, but I think they're a lot cheaper now. Plus, you can use it with your gigging amp.

I've got a song in the works at the moment that I recorded solely with the GNX4 that will be posted hopefully within the next week or two. I couldn't live without it for recording.

But I know you said you want an amp, but with recording that means you'll need a good mic as well. Another good thing about the GNX4 is it also has a microphone preamp for recording vocals :). Ok, Ok, seriously, I don't work for them, just enjoy the product very much.

Feel free to ask away. As far as practice amps, I don't know, I just have a little 10w amp for that. And I don't use it for recording so....
