As the header asks.

I would love to see any current ES-335 kits modelled and modified so that either the F holes were as large as standard Gibson F holes [allowing full sized pots to be installed - only MINI pots can be installed ATM]
OR
Have the centre block drilled like current ES models, so the the wiring can be passed through a space in the body on the control side of the Bridge Pickup.

I would also LOVE to see a ES 335 model, routed as above, but also for REAL P90 Soapbar pickups.

P90's in Humbucker mounts, are NOT P90"s.....forget it, they are different things.

You would have a unique and highly wanted product if you chose to make it.
How many of these have you seen?

A much wanted build I suspect....I'll certainly buy a few, just so I don't have to re route the current ES-1 body
