I had a hs3 on my old strat - i loved it. its a really nice pickup, not very high output tho - its got an old school single coil strat sound, except its hum cancelling so u can crank it up on the amp and it still stays quiet. I had it in the neck position and it sounded awesome for heavy blues solos.
ive never heard a YJM though, are they much different?
Im lookin to buy a set of them for my new strat (my old one got stolen) so i'd be interested to hear how you get on!
I have an HS-2 and YJM in my strat, love both of them. I'd sell em to you but I like em too much

Free bump for ya!

I've had tube amps for a while now, but never actually had any go down on me

maybe you're not saying the right things? an amp likes to know you care.
