I want to suggest a superswitch combined with a BMP-1 diagram that will have this combination
1. Neck Only
2. Neck + Bridge North coils humbucking
3. Neck + Bridge
4. Neck + Bridge South coils humbucking
5, Bridge Pickup
I'm not good at superswitch combinations, but this is something that the BMP-1 is unique in being able to deliver.
I have an Ibanez 2120x donor guitar that I am happy to make a pictorial record if someone maybe called Frank can perhaps help me work this scheme out.
