I use a telecaster, I have yet to use my stratacaster, I really like using my les paul but it is a little heavy and if I am inteading to play a while I use the telecastor, I am 40yrs old and have a couple guitars.
I just started playing guitar in Jan 2012 with Rocksmith. I purchased a Fender HHS tremolo Strat for about $120 here on Amazon. The guitar has been a great starter guitar. I have since replaced the bridge, strings and springs in the guitar and now I really love it. It is amazing how far I have come in a few months using Rocksmith
I'm switching back and forth between an all-white California Classic, and two Route 66 Vintage guitars (one Honeyburst, one Goldtop). All three guitars are from Monoprice.com. I tried with a Fender Starcaster, but the action on the strings is too hard to be able to play without excessive finger pain.
The California Classic is ideal for playing while seated, while the Route 66 guitars are great for standing up.
