I have 2 custom Tele Deluxes I built, an all mahogany one with a pau ferro board, and an ash one with a one piece roasted maple neck, along with an ES-339. I have been trying strings for a year (round & flats wounds). I stumbled across the XL Half Rounds recently and was thoroughly amazed. They are the best of both worlds with a sound all their own ... by far better than the "best" strings I have paid 3 times the price for, and the easiest to play. I use linear pots for everything, and with the combination of strings and pots you can play anything you want, all night long and still want to play more. Can't say enough about these strings. Try them regardless of what you play.
