Used a new prototype UL 310 on the gig last night along side my Epifani UL 310. It gave my Epi a run for it's money tone wise. The Epi has it's own "voice" so to speak and so does the LDS, but it is in the same ball park, hell maybe batting clean-up! It will be a serious hard choice between the two, even more now that Epifani raised their prices 20%. Also put the new prototype 410 UL from LDS through it's paces at the shop today and it performed amazingly. And any 410 that I can lift up to face level (it's around 50lbs) is killer! It has the same tone charactistics as the 310, but as you can guess a little louder. I'll post some specs and prices as they become available, but the 410 is going for around $700 to $800.
