Here's what the guts look like as well as the controls. the 2 controls to the left and middle are push/pull and all 3 have a top and bottom adjustment.
from what I saw on the warwick website this is a "non-standard" control arrangement so I've never been able to actually know what each is responsible for.
I've played around with all of the knobs, buttons, and levels inside the battery compartment and the think still sounds metallic and clanky as hell - not at all like other warwicks I've played.
it's a shame too- I NEVER EVER use this thing, even in practice, let alone playing out
