anyone play bass guitar?

Carvin has a pretty good jack and it's reasonable. Go to www.carvin.com click on guitar hardware..

here's a sample: http://www.carvinguitars.com/products/single.php?product=FJ1C&cid=42

...btw, yes, I'm a bassist and have been playing since the late 50's. ;)

Rock on... as we used to say back in the day.
