Anyone ever seen an external inline (along the 1/4” instrument cable connection) vol/tone pot sorta gizmo. Something that hangs along the cable and can be adjusted without going to an amp or pedal.
Came up today in a convo.
Can’t believe it doesn’t exist.
Just sold my Traveler bass with a piezo only and the guy was asking since the bass has zero controls.
Googled but found nada.
