I'm not sure if it's an addiction for me...I think it's more the fact that I find a couple of Fender's models comfortable to play....
I've been really fortunate to have tried out loads of different guitars that belonged to friends (mostly vintage or US models, as well as various outstanding Japanese Fenders)....in the end it was just a no-brainer...the Jazzmaster won, and the Telecaster was second.
since I'm pretty tall I like guitars not feeling like toys...then, it's the necks, they need to feel nice with my long bone-y fingers....I just don't buy guitars anymore because they look pretty.
to sum it all up
Gibson ES335/Epiphone semis - great sounds, but they just felt weird against my body...they also felt quite fragile - cross off my list
Les Pauls - good sounds through certain amps, they felt small though, and they got heavy on the shoulder after a while - cross off the list
due to the two above, I think one day I should try one of them now discontinued, Les Paul Florentines...maybe they'll be the Gibson for me...preferably I'd find one with P90s...but I'm pretty sure they only came with humbuckers
carrying on....
Gibson SGs....GREAT rock sounds...I love SGs....but...they feel like I'm playing a banjo...and I also feel I might snap them by accident - cross off the list
Gibson Firbirds - I've played several...the necks are very narrow near the nut...but apart from that KILLER guitars - I love them!
Rickenbackers - narrow on the neck...I understand there are models with wider necks, but I haven't played any - they only really do one sound...but what a sound.....I need more sounds though - so cross off the list
Gretches - WOW...I love the sound of the hollowbodies (also playd a silver jet and a duojet - very cool too)...I've played a White Falcon through a plexi and it was a religious experience...they are OTT though, and I don't like that much - off the list
Ibanez guitars...I've played various ones...I didn't like the neck radious...but they did make me play Iron Maiden's "The Trooper" a lot!
onto Fenders...
The Stratocaster...I just cannot get on with them...I end up turning off the volume while playing too...I don't like the sensitivity of the tremolo either, an dI don't like the "quack" - off the list
Jaguars - too cramped, great sound....but with my big hands..

. - off the list.....other student models go off the list too due to the comfort factor
so it boils down to the Jazzmaster and the Telecaster...I could have 20 of each!
the Telecaster is so robust...and the simplicity just urges you to get on with becoming a better player
The Jazzmaster hangs perfectly, has the brilliant tremolo system, the neck sticks out more (I love that, as I'm pretty tall), it sounds shimmery, but can also scream.....and let us not forget....it looks GREAT!
when I was younger, I wanted one of every guitar, to get different sounds etc....nowadays I've settled on the sounds I like, and look for a comfortable guitar that I like playing for hours, instead of a guitar that I tolerate for hours in order to get a specific sound.
what 'm sayin' is....I have done "Back In Black" with a Jazzmaster through a Marshall...and you know?.....it didn't sound half-bad
so there you go...an insight of why I like Jazzmasters.
my 2p, different strokes etc etc
