I've a new to me '73 Gibson EB-L. It's had some mods along the way and I'm trying to understand what's up here. There's a battery pack and the tone pot is much different than anything else I've ever seen. Is it some sort of active tone? If so, what's it do? Other two pots are volume for each pickup.
Thanks in advance for the help. (labels on tape are B for bridge, N for neck, T for tone)
