Re: should i get a jb jr for my strat?
I have a JB Jr. in my strat right now and my buddy uses a strat w/ 3 Hot rails, and he has a shred guitar w/ JB. Here's my take on the three.
1. The Jb Jr does not sound like a full sized JB. Not as full, rich and the harmonics aren't as willing or lively under high gain. Not as much chunk and thunk. This principally is due to the size of the magnets in a full hum and the wider spacing in a full hum vs. the Lil/rails.
2. The HR to me, sound darker than the JBJr., and IMO, they don't really feel too alive or responsive. I just can't dig the cleans and the dirties are uninspiring.
3. The JB JR. reminds me very much of a hotter tele pickup, with a bit less treble/highs. I do think it's ok for a noiseless hot pickup when you don't want to alter your guitar's cavity or pickguard (my situation).
It's a fun little pickup for what it's worth, but I think the name is a bit leading-it's a SC-sized, humcancelling, hot pickup.
I think single coils and full HBs are the way to fly. You get better response and feel from them and each is not trying to be the other.
