In addition to building and working on my own instruments, I'll also take in customer's guitars to upgrade/modify. Here I've got a really great set neck Telecaster with DiMarzio humbuckers that the customer wanted to modify. The original controls were Volume w/P-P to coil tap, 3-way, and Tone; for the upgrade, I swapped the volume and tone locations and used a stacked volume instead of a master to allow greater control while putting the push-pull on the Tone pot (now the forward pot).
