Hello, I’d like to know if the TV Classic with universal mount would fit on a Gibson Firebird V (two Firebird mini-humbuckers), and in case what kind of ring would be recommended. Thanks in advance.

Gibson style mini humbuckers are generally narrower pickups (1-1/4″ wide). Filter’tron pickups are wider (1-3/8″). Measure your pickup cavities. Should be at least 1-3/8″ plus…
I recommend the EM-2 Gretsch mounting rings.
