What song made you fall in love with what guitar?

I grew up around guitars, having two older brothers who both started young. I always liked guitar, though I didn't start learning until I was almost 18. I was always partial to Gibson's, Les Paul, ES335, etc. In 1977 I went to my first big concert and saw Queen. I knew very little about the group except that the tone of Brian May's guitar was different from anything I'd ever heard. At the time I didn't know that the guitar was home made, and I spent a few weeks trying to figure out what kind of guitar it was. This was long before the internet, so information was not easy to find. I remember finding out that it was a one of a kind, home made guitar, and I was disappointed that I couldn't own one like it. In 1993 Brian May worked with Guild to make a limited amount of the first quality copy of the "Red Special" and I placed an order several months before the expected completion date. It was the first new guitar I ever owned, and my first high quality guitar. I still own it, and its still in pristine condition, and I still love that violin tone.

Stephen Stills with older Martin Guitars (which I have never been able to afford) and, much to my surprise, John Mayer on the DVD 'Any Given Thursday' doing 'Lenny/Man on the side' made me a Strat player for life. The clean tones and melodies he got off that production model SRV signature made me have to have a strat.

Here's a sample of the sounds he used to make. It's only audio since most of 'Any Given Thursday' seems to be blocked for some reason. If this doesn't make you fall in love with a clean strat I don't know what will https://www.youtube.com/watch?v=74sMY_Zeir4

Well after seeing my first concert " Black Sabbath" (1973) I just had to have a SG.....( War Pigs, Paranoid, Sweat Leaf, NIB etc )
The scream and sustain hooked me..humbuckers vs single coils
I still own that first Sg 1973 ( cost me 375.00 with paper route money) ....she has since aged very nicely & sounds even better
over the years your musical tastes change....but I'll never get rid of that 1st Sg.

It has to be the Fender Stratocaster as played by Hank Marvin on Apache. I was very young but I was hooked!

It was to be many years before I bought my first Strat and in the meantime (early 70s) I had an affair with an SG copy after hearing the Hot Rats album by the great Frank Zappa not realising that he had used an early Les Paul Goldtop with P-90s for most of the album. Willie The Pimp still ranks very high in my list of favourite guitar solos.

Not one song as such but when I heard UFO's Lights Out album I knew it was "guitar" music for me. Then a number of years later when I first picked up the guitar it was Michael Schenker that stood out for me.
Tastes have changed back and forth over the years but it's still "guitar" music for me, thank you very much...

None.  I liked certain guitars because of certain players and certain bands, but never really one song.
