If memory serves :
theres obviously volume and tone, I think theres a filter sweep style tone control..similar to a tonal balance...maybe like a fender tone stack?
Theres a mutron inside it too.
Its funny. you plug it in and it lights up..wich is cool, but Ramsey Lewis who Billy played with at the time, didnt like the lights..got in the way of his stage importance
, so I think either ken or someone ended up making a box for it to shut the lled's off.
Another silly side not, in Billy's first vidoes featuring the 6, youll hear the filter kick in during a solo or 2, its by accident..when he goes, he goes and anything in the way gets knocked over
Hey Bob, are those the origional pups? Do you know if Bill Lawrence did those? billys bass has Barts in it.
