I'm trying to decide what to put under my Avatar 210. I'm looking for a tight sound that will cut through with clear midrangy punch. I hear the Bag End S15-D is quick and punchy for a 15, but would it make me happier than an Avatar 212. Volume between the two isn't a concern. I've got plenty of wattage. Cost is also not a concern. Also, I only play 4-strings.
