This year I finally decided to take my playing seriously, and am taking lessons weekly. Problem is, my bass is driving me nuts. I have a Carvin LB75 Fretless. I finally got the thing set up correctly, but am having issues with areas of the neck sounding "flat". I also find that the neck tends to move around a lot, so I have to fiddle with the truss rod fairly frequently. I have decided to start looking for a new instrument. I am left-handed, so there is NEVER a left-handed fretless in stock anywhere, and typically the only lefty basses around are the cheapies. Whatever I end up getting will be special order. Some things I would like: 1. I have small hands. The Carvin I can play comfortably, so I'd like to avoid anything with a wider neck. 2. I can't stand active electronics. I prefer passive only. 3. A neck that stays where you put it (most of the time). 4. A bright clean tone I have found some right handed Pedullas which sound nice, but the price is a bit crazy, and the neck feels funny, I think the radius may be different. Been looking to try a Thumb 5, but it looks like there is no passive option for those basses. Why is it that the passive option seems to only be available on the 4 string models? Experiences and suggestions appreciated.
