| Yup, I agree with Darren (Les Paul). Funnily enough it's easier to make an reasonable electric guitar than it is to make a reasonable acoustic, so while you can buy an electric like a Fender Telecaster (electric) copy for around £150 notes that, although it's never going to be a great guitar, will be quite playable, you'll need to spend a couple of hundred quid more to get the same playability out of an acoustic.
Don't skimp though. If you fall into the trap of buying a cruddy old plywood acoustic with a crap tone and strings that are four inches above the fingerboard on the basis that 'a cheap one will do to learn on', then your kidding yourself. A guitar like that will fight you all the way as you try and learn on it, even an experienced player would have a hard time making it sound good so you'll just find it very demotivating. It would be a bit like learning to ride smoothly on a bike that had a jerky throttle, knackered shock absorbers and false neutrals everywhere.
If you're going acoustic, far better to spend £300-400 on a half decent guitar 'cos then if you don't get on with it you can always eBay it and get a reasonable amount back  |
