So, I'm in a bit of a weird spot here -- I've been learning bass for my band and have been recording by just plugging into my interface and using VSTs in Reaper. However, I'll be travelling to the family farm soon for the holidays, and need to practice on the road, and I'll be away from a decent computer for most of this. Since I don't have any amp, this leaves me needing some kind of portable rig that can be used for practicing without a computer. Does anyone have any suggestions for this that won't break the bank?
