I did perform a few mods/changes on my Wal Pro 2E... fitted a D-tuner, fitted Schaller straplock buttons, swapped the pickup toggle switch for a rotary one. I kept the original parts and these changes have now been reversed (apart from the strap buttons, and it'd take seconds to change those), and it's back to factory stock. Many years ago I did contemplate having the pickups and electrics changed to Custom spec, I'm glad I didn't.
