hi, I know nothing about telecasters, I need to know of a good quality one around the £100 region
My first guitar was a Squier Tele Affinity Series, and honestly, it has kept up extremely well. Granted I normally play a gibson les paul studio, the Tele is still in great shape. If you're wanting one for that price you can't go wrong with the affinity series, imo.
Good quality for £100 is tough to find, id go with a squier, but its not exactly a great quality, but still go for it.
If I were you, I would get a nice one reguardless of price, so that way you end up not using your first guitar after a few months because it's just a beginner's guitar.
Have a look here:
