In recent times I find myself increasingly disappointed in my Yamaha RBX series 5-er. I can't complain though, I've had the bass close to 3 years and in that time it's actually been one of my best basses. It was my main bass for church playing and various university stuff, as well as being the bass I learnt to slap on. But now I've largely quit playing worship and have also begun to move away from indie and rock (which is what I originally played on bass) to learning jazz, funk and fusion, and now the tone and feel of this bass is beginning to really hack me off. It feels muddy, the B string too muted and the bass bulky to play. So I've come up with three options: mod the bass, get a new 5er or simply scrap the idea of playing 5ers for a while and stick to the 4er fretless I have. Major problem with the last of these options is that there are times when fretlesses aren't going to do the job or sound right. I also have been tempted towards the new bass option as I've found an Aria unlined fretless 5er which would combine something I have always wanted (an unlined fretless) with something I need (the B string). I'm not tempted towards modding for the simple fact I'm not confident in doing so, and it could prove to be not cheap.
