Within the next few months I hope to be purchasing a 4 string fretless bass. My two current basses are a Music Man Bongo and a mexican Jazz Bass. I play all kinds of metal, from death to doom and lots in between. The main fretless basses I have been looking into are of course a fretless bongo, some kind of fretless fender (USA), a warwick thumb, a peavey cirrus, a stingray, or even a lightwave bass. I love the feel and sound of my bongo but I wonder if I might want a tone that is a tad less aggressive and more organic for a fretless. The only basses id be able to try out in a store would be the warwick, the ray, and a fender. I always feel the need to try before I buy but no ones going to have a fretless bongo or lightwave bass for me to try. Just looking for some kind of advice based on experience.
Actually it was the first bass to ever have a Lightwave pickup system installed (long before Lightwave created their first bass of their own). It was a ZON Sonus fretless with a spalted maple top on it, some may remember the bass from a Bass Player review in the mid '90s (I think Flea was on the cover).
