My Essance 93k 7563 seems to have diffirent actives to what I see normaly I've got bass & treble EQ. Pan and Vol and also Sims led's fitted into the fretboard.

Please, good sir, post a picture or six.
 
Are the bass/treble controls knobs or switches?  Does it still have a filter control?

The bass & treble are control knobs. No filter control

Hi there, the knobs and switch do not look standard, can you take a photo of the control cavity so we can see what is inside there.  
 
Welcome to the club it's great to see another alembic player on this side of the pond.

The Led's were already fitted when I bought the bass in 1999/2000. The switch on the front is for the Led's.
