I have a 1979 Deluxe Reverb that has the stock Fender special design speaker made by CTS. It sounds pretty good but is lacking a bit in clarity, definition, and sparkle - even when compared to a SF DR with a Utah speaker. I'm just about ready to purchase a WGS G12C speaker. The G12C is based on the vintage Jensen C12N. There is also a WGS G12C/S - smooth cone version that also seems to be a popular replacement speaker for a DR style amp. Does anyone here have direct experience with both the G12C and G12C/S? I'm inclined at this point to get the standard G12C based on the reviews I've read so far. Thanks!
