I am looking for a 10" speaker that would be suitable to play both bass and regular guitar through. These would be for a MusicMan HD130-410. I have a buddy who plays bass and guitar about equally and he wants an amp that he can use for both. I have this HD130 that he is interested in, but I don't think the stock speakers will cut it for bass. I know the amp itself sounds good for both bass and guitar. Any recommendations?
