Other than the obvious watt /headroom difference, how do they compare in applications? They are similar price bracket. It's seems -from the little denied I could hear of the LB30 that it's sound very warm, smooth and "vintage", chunky I'd say. I like! On the other hand I wonder if the ABM Evo iii 500 head might be even better. Couldn't hear much on YT but - what kind of amp is it, what kind of styles it fits? Of the two which would you pick with a 5 string fretless? Thanks!
