Although I haven't found my ideal Fender Stratocaster yet, I own three guitars that owe more than a little to the body shape.
After Leo Fender sold his business, he soon realised he wasn't ready to retire, so he formed G&L with his old friend George Fullerton - G&L is short for "George and Leo" - and set about fixing what he saw as the mistakes he'd made when designing the Strat the first time around. The result was the S-500.
I bought mine second hand from Intersound, the same guitar shop in Dursley that sold me the Squier Custom Telecaster I've already mentioned. I was surprised how much I've used the extra fret (it has a 22-fret neck, as opposed to the Strat's more traditional 21 frets.) Apart from surf guitar, it's also great for getting more Gilmourish tones...
If you need a surf guitar
well, of course it must be blue
and kitted out with a whammy bar
to make your surfing dreams come true
Add a dash of spring reverb
so it'll sparkle in the Sun
that's all you need for it to sound superb
Just plug it in, and have some fun
I know the headstock
doesn't look the way you thought it would
And it goes by another name
But its designer wrote the book on guitars sounding good
It's Leo Fender's, all the same
It's not too understated -
the scratchplate adds a touch of bling
And every change was calculated
To make this guitar just the thing
I can't resist the urge to play it
When it sounds and looks like that
I'm going to go ahead and say it:
I think it's better than a Strat...
