Chris, one other thing I thought I'd mention is that if your lad really takes an interest, get him a few professional lessons, especially just covering the basics.
In my experience, nothing puts kids off learning an instrument more than a perceived lack of progress or achievement. Someone who teaches guitar will recognise this and tailor their tuition accordingly. I could have taught my daughter to play but that would, in my honest opinion, have been far too limiting for her. I learned music at school so I can always help out with the theory, but I am self-taught on the guitar so all could hope to do is teach her to play
like me.
I really wish I'd had lessons, I think that if the correct practises are taught early enough, then bad habits are less likely to form. If I had lessons now I'd probably have to change so much about my technique that I'd be better off trying to play
left handed from scratch!
The guy who teaches my daughter at school is big on technique, and that foundation will stand her in good stead if she decides she wants to carry on learning the guitar. But he's absolutely on the ball when it comes to keeping it interesting. He teaches theory in direct relevance to the guitar - leaning heavily on understanding rhythm pattern, as well as learning where all the notes are on a guitar neck. But most important of all, they get to put their acquired knowledge into playing songs
they like - both in terms of melody and backing (e.g. they learned 'Chasing Cars' recently).
I just looked in the Argos catalogue for you Chris and they don't seem to stock the package I bought anymore.
The closest I can find as a package is
THIS - if he doesn't mind the colour!
If you wanted to pick up a small practice amp separately, they currently have a single pick-up three-quarter size Elevation guitar on offer at half-price (£24.99)
HERE.
You might also want to check out Ebay too - these Elevation guitars seem built to take a few knocks and I'm sure there will be plenty of unwanted gift items floating around. I'd recommend searching locally for something you can go and pick up because the cost of shipping could easily wipe out any saving you make buying a used model.
I use a couple of excellent Ebay search engines for seeing what's available locally; there's one from Martin Lewis's (the financial expert they have on
Watchdog) site
MoneySavingExpert.com HERE, and there's also a local search function available on BayCrazy.com
HERE. BayCrazy also has some other really brilliant search engines on that site, including "Auctions ending in less than 30 minutes with Zero Bids" and "Misspelled Items" (type in 'Amplifier' and see how many people have spelt it 'Amplifer'
