I picked this up as a bit of a change in pace compared to my other Charvels - this one is equipped with a Kahler, USA made, fulcrum tremolo called the “2520.” This trem is similar in design to a modern strat trem, with two anchor points instead of the traditional six, and the addition of fine tuners to pair with the locking nut at the headstock. While it’s not a true double locking, floating tremolo like a Floyd Rose, it’s actually a very good bridge - and quite forward thinking for the time. It gets a pretty bad rap around the web, but I was impressed with it, although my expectations were low which helps. The biggest detractor is that the spacing of the studs is too close for a direct swap with just about any other bridge - anyone who had an ‘86 Model 2 or Model 3 with this bridge would have to plug and re-drill holes in order to upgrade the bridge to something else.
I personally would never modify an original like this one, which happens to be in fantastic shape. The factory J80C pickups are meaty and thick sounding, similar to Duncan Customs, and I think this pickup sounds incredible in the neck position even if a bit high output. As long as the heights are adjusted, the volume difference isn’t too bad, and a 3-way blade switch makes it easy to switch between them. Later 3A’s had the 5-way blade switch, which gives split coil sounds in positions 2 and 4 but this particular one is too early for that feature.
