A friend of mine gave me a GCB 95 Crybaby that he wasn't using and I was considering a drop in kit and TB footswitch as a "project" just to see how it would turn out. I looked at the Castledine and the Area 51, and the internal trimmers and the halo inductor on the Castledine has my eye. Has anyone compared both these drop in kits? I'm wanting a vintage sound with some good vocal quality & "quack". Thanks!
