First, I'm curious where you live, dude. :) If I recall your posts correctly, you've just picked up the guitar and already own a Tak and a Martin and "found" an amp gathering dust in a corner?

I am merely a humble GT student like yourself, but as far as strings, my own personal preference is 10's. I use them on my Squier Strat after having used 9's for a while. Actually I still have a few guitars with 9's on them, but the ones I play much have been switched to 10's.

SRV reputedly uses 13's. Maybe you can research your favorite Blues player and check out what they use. I dig SRV (a lot!), but I don't think I'd like playing 13's.

You could hold off on the 10 pack and try a couple sets in different gauges. See what you like. I assumed I would like 9's but my personal preference after some experience led me to 10's.
