Mica:
Can you estimate how much it would cost to convert an early 90's large bodied Series I to current Series II electronics? (CVQs, master volume, pickup selector off the horn?)
 
Thanks in advance.

Are you looking for standard Series II controls or Steve Style with a master volume/pan arrangement?

Standard Series II, I suppose...including moving the pickup selector off the horn towards the rest of the controls.  Also, would Steve style be less money?  
 

You're probably looking at about $450 to do the migration to standard Series II layout. We'll put a new brass plate where the pickup selector switch was, you can have it engraved if you like. Add another $750 to get the upgrade (removes directional and HF noise from earlier circuits).
 
Steve style is definitely more money.
