I never thought I would play a bass guitar that I liked better than my upright - and I still haven't - but I have found one that comes close.
A good friend has been allowing me to play his Rob Allen MB2 - which I adore - but was scared to death of damaging it. I had played a Godin A4 previously and liked it, so I decided to buy one since I got a great deal, and I was having trouble finding a MouseBass I could afford! These things have a great woody/acoustic sound and probably the punchiest piezo I've played.
This is an older model - mid '90's, I think I was told, so it doesn't have the synth output (What's a synth, anyway?). It has virtually zero wear but does have a couple of cosmetic flaws: the wood on the top around the truss rod adjustment hole is dinged, and it looks like some sort of mild solvent (or straight vodka, possibly?) ate a pin hole though the finish on the top. Otherwise this thing looks like new - and plays like butter.
The previous owner had some DR blackies (coated round-wound) which I immediately swapped out for some LaBella Tapes. Must not have been played much - no fretboard wear that I can tell. Plus, the truss-rod was so out of adjustment when I got it that it was unplayable.
My only complaint - and it is a fairly common one with these - the upper register tone adjuster just doesn't seem to do much. That said, everyone that hears it says it sounds great!
