I have a few amps - Eden WT400 - Aguilar DB750 - Ashdown ABM500RC.
I use the WT400 for rehearsals and small to medium gigs with either an Aguilar GS212 or Eden D610XLT and I use the DB750 or ABM500RC with either the Aguilar DB810 or GS412 for larger shows.
I owned the LMII for a couple of...
These are all saleable amps so I would buy the Shuttle, have all three for a while to see how they work for you, then, sell the one that isn't cutting it.
Just a thought.
Out of those two, I would have called the top one Daphne and the bottom one Sonic... not sure though, as the lighting can make it hard to distinguish the differences????
Both very nice though!
