I have had conventional tuition on the guitar, and yes, I've learned a bit of jazz/blues, but my teacher pretty much teaches me the styles I want to learn, so I do classical and rock/metal as well.

Also, I just want to say by technical I didn't necessarily mean difficult. And for composing for instruments you can't play, I never said you can just blast away composing any old crap for any instrument that you don't actually know how it works. Obviously you have to have an understanding of how the instrument you compose for works, but that doesn't necessarily mean you have to be a proficient player at that instrument.
