I have a 1967 Fender Vibrolux reverb with C10NS speakers in it. The low end is starting to go out quite a bit. My other guitar player has an identical Vibrolux and when I swap cabs you can really tell. I've been stuck between trying to find new speakers or having them reconed. The amp is in extremely good condition. I'm wondering about how much value is placed on original speaker cones in vintage amps. If I get them reconed, should I expect it to lose resale value? I may still do it regardless, but would like to at least make an educated decision.
