I'm looking for a really nice bedroom practice amp. I always end up writing something and wondering how it would sound through a proper tube amp. I figured I'd look into building a smaller Fender design. Before I think about which model here's my concern. I need to be able to have both clean and overdriven tones at similar volumes. Would a Champ or 5F2 kit be pointless then with just the single volume control? I can think of a few different methods for implementing a Master Volume or even a VVR attenuator of sorts. Next question . Which model would you recommend? I play a lot of ambient stuff and live in a city so it can't be too loud. What are the major differences in the 5F1 and the 5F2A? Thanks..
