Hi...and sorry for probably sounding like a moron. I don't know much about changing pickups, but I've been playing for a while (I'm originally a piano player) and have decided my Jaguar sounds kind of thin and trebley. Additionally, the stock pickups are starting to crackle and crap out. I'd like to keep some of the unique, trebley sound of my guitar (i.e. the "lead" circuit), from which I can get great surf/rockabilly sounds, but I'd also like to get a fuller, bassier sound for playing rhythm. I've played a lot of guitars with humbuckers appreciate the way they sound and would like to get as close to that as I can on my guitar. I think hot rails, cool rails, and the little 59er all look like great options, but I'm not sure if I can use them since they're strat pickups. I see the dimensions are slightly different from some of the jaguar pickup dimensions, but has anyone tried putting single coil-sized humbuckers on a jaguar? And if not, can any jaguar players give me advice on what to use? I'd like to be able to get a nice, bassy modern-rock rhythm guitar tone while maintaining some of the jaguar's characteristic sound and versatility. Thanks for all your help and sorry for writing so much!
