Hi all -- for a while I've been planning to build something roughly equivalent to a modelling amp head. The idea is to use a Raspberry Pi (credit-card sized barebones computer), some kind of USB sound card, and -- at least initially -- the Guitarix amp modelling software as a base. It would have an LED touchscreen to allow configuration and adjustment of the modelled stack. As all of the amp modelling would be happening in software, the power amp stage could just be a class D or "class T" amp attached to the line out of the sound card. Should be easy enough to build a decent case to keep it all tidy.

I see that pretty much all of the threads here are to do with making classic analogue amps, so maybe this isn't the right place to post build notes/thoughts on this... on the other hand a lot of the posts elsewhere on the forums suggest that people are using digital amps when playing, so perhaps there might be some interest?

I've done some initial tests of the stack apart from the power stage, and have something roughly working -- will post a bit about that next, but if the consensus of the forum is that this isn't the right place to post about the build, just let me know and I'll stop
