Personal taste and aesthetics are a funny thing. I just wondered if there are any elements of bass design that folks just can't get past... Things that mar otherwise fabulous basses... For me there are three things.
The bridge on a Lakland. I have a chum who has the most lovely Lakland 5-string. Sounds amazing, plays like a dream but for some reasaon I just can't abide the look of the big oval back plate on the bridge. Same for all Lakland's models. I couldn't have one on my bass. Therefore, for me, gear options are cut down by one top maker just because it doesn't do it for me... Totally irrational, coz they are lovely basses.
Varnished fingerboards (and maple ones for that matter). Just never liked the feel of a varnished board or the look of maple over rosewood.
Modern single cuts. For some reason they almost all look wrong to my eye. I have a chum with an amazing Curbow single cut. Again plays great and sounds great but the look just puts me off. In fact I can only think of one single cut where I thought, cool looking bass - an Adamovitch played by the bassist in my nephew's band.
So what is it that, for no real good reason, puts you off a whole raft of bass designs?
