Electricians are tradespeople, like builders, plumbers, I'd include amp techs in this category.
I wouldn't base my degree choice on amp/pedal designing, they are very very simple circuits, and deal with very old technology, you will be very overqualified and underpaid to be an amp tech ect I'd be surprised if they mentioned tubes at all in a EE degree, asides from 'back in the old days some people used these funny old things'!
From what I've been told from the EE's I've chatted with most of their work revolves around PLC design and maintenance for industry automation, they spent most his time sitting in a freezing works,saw mills, food processing plants with his laptop plugged into the PLC. he doesn't own tools and hasn't had to solder since the 1st year uni labs.
The hands on stuff is for the lowly sparkies, you do a degree to get away from the hands on stuff, not into it ;-)
Amp techs/designers learn their trade through tube amp bibles, hands on experience, and experimentation, check www.aikenamps.com for some introductory tech info/Recommended books.
