I assume most people on here started with a fairly atrocious guitar on which they learned to play guitar. Usually as gift from parents, or because you didn't know what to buy (ooh it says stratocaster on the headstock!), they are monumentally terrible. My first electric guitar was a Hohner Rockwood, which came with an amplifier, and my God was it awful. Of course I only found this out when I played a nice guitar and went back to my piece of crap.
So, with a budget of £150, what would you buy for a beginner?
I would probably recommend an Epiphone SG like this one:
It will be nice to play and sound quite good. I would imagine the only problem with this guitar (for a beginner) would that be it will go out of tune all the time, like most Epiphones I've ever played. Plus, it is £129.
