I recently posted a thread on my search for a lightweight bass.

I've suffered from back problems since my early 20's, and been in and out of hospital countless times, but I've carried on playing the basses of my choice until now.
At 59, it has finally got to the stage where I just can't carry on playing my favourite bass, which is a Warwick Corvette std bubinga (pictured in my avatar).
It is a fantastic bass to play, the build is outstanding, the neck is so tight in the body, it could almost be all 'one piece', the wood finish is fantastic, and most importantly, the sound and playabilty is unbelieveable, and I will probably keep it for ever.
BUT!
Despite all that, it weighs well over 11lbs, and the pain has got so bad that the only way I can carry on, is to get a very lightweight bass, which I did last week when I found myself a second-hand Ibanez SR500, it is only half the weight of the corvette, but it plays and sounds good, and the balance is great, and it means I can hopefully carry on for a little while yet.
I've also just sold my fantastic Ashdown rig, and spent a lot of wonga on a lightweight Genz Benz Shuttle rig (very nice indeed).
So for me, weight is important, but if I was fit and well, then like most people, I would probably think that 'lightweight' is just the latest fad!
