Modelling amps can model a lot but to me they present a representation. Hands down the amp I use the most is my Rolland Micro Cube. 3 watts of tone from acoustic to something like Judas Priest. And this is important because it's no fun playing Priest with an acoustic tone - at least not to me.

Gear is a lot of fun and I enjoy messing about with mine. If you think you might want to create your own tones, an effects board

may be something to consider. I just spent the last hour playing with mine. And play is the operative word.
