My girlfriends dad has a set of Roland V drums that he is playing through a crate gx15 right now. it sounds like garbage. he would like to get a new amp but doesn't want to spend very much money. these are simply for him to play at his home. doesn't need to be anywhere near a gigging volume level. i don't think he wants to go over 150-200 dollars. so i was thinking maybe some decent powered studio monitors (or single reference monitor and just run them mono) that he could put on stands behind the drums for like $150. i ws also told a keyboard amp, but the ones i've seen that weren't like Gorilla were over $200, and a little big for the amount of floorspace he has (also why i considered monitors on stands). any ideas?? i know very little about v drums
