Light Teles? New one to me Matt 
You could buy a new guitar, or you could just get a new strap maybe? My Thunderbird (bass) weighs quite a bit, but it has a wide strap on it, so the weight is proportioned well. Sg’s are very light, Mosrites…..what are you using now?
I have a few guitars, and all of them are fairly light, I have had the back woahs with the les paul and tele. My strat is light….there are tons of light…good guitars out there. The Melody Maker is recomended by J. Mascis you know.
