Hi all, I just purchased a flat-back bass. I've always played with part my my knee touching the back of the bass and it's never really been a problem in terms of volume loss or sound dampening. On my new bass the sound loss is quite drastic. I'm not a tall bass player so my teacher and I have worked hard to find a comfortable posture for me to play in (rotating the bass a little bit inwards helps when sitting.) So the question is....Does anyone know of any sort of device that clamps onto the C bouts of the bass that can stop dampening. I've heard that some bassists get someone to carve them a long piece of wood that clamps onto the back of the bass easily (with rubber attatchments)...That way you can put your knee on the device and have nothing actually touching the back of the bass...Does anyone know what might work? A Danish bassist recommended the "play on air" viola shoulder rest, but I have no idea how a Viola shoulder rest could ever be long enough to clamp onto the back of a double bass. thx!
