I placed a DiMarzio WillPower (neck) between 21st fret and front MFD ceramic (take a look to thread "show you three pickup basses")
Other than that, honestly never thought about a pickguard, bein' it for either L2000 or L2500
Yet, to be of any help... Take a look to Ibanez Srx530
Ash body (3TS finish) and ceramic humbuckers
