Wait until you're older and the budget opens up a little.
For me it faded away when I got older, looking at it by age
14 - Xmas 2000 - First guitar, Squier Strat Pack from argos, with 10w amp.
15 - 1 month later - Danelectro compressor
15 - Xmas 2001 - Marshall AVT150 combo
16 - 1 month later - Zoom 707 multi effects unit
16 - April 2002 - Seymour Duncan JB JR bridge pickup
16 - August 2002 - Went to Cardiff with my dad to buy some strings for his bass guitar, I tried out a Fender Fat Strat (with floyd rose) at the Cranes music shop, played it for 45mins and then went home and me + my dad convinced my grandmother to allow me to use my savings (made with her money) to buy the guitar.... Went back there on the monday and bought it.
16-18 - Marshall Bluesbreaker II pedal, Seymour Duncan Full Shred Bridge pickup, Seymour Duncan Lil59 pickup, Seymour Duncan Duckbucker pickup
17+ - Faith Venus acoustic guitar. At some point I had this for christmas, but I can't remember when, all I remember was that it was after my father passed away, perhaps christmas 2003, would make the most sense.
18 - November 2004 - Marshall 1960A cab, 2 weeks later... Peavey 5150 head + matching cab (sold the cab to my bands other guitarist and kept my marshall) + Digitech Digital Reverb and Digital Delay pedals. I had my student loan to thank for that.
19 - January 2005 (my birthday) - drove to Reading (England) to buy a 1994 Ibanez Jem 7V
19 - February 2005 - Bought a 10w hand made studio amp from a guy in Dover, drove down there to pick it up + to get my Peavey 5150 Bias modded and revalved.
19 - March 2005 - Jim Dunlop Crybaby Wah.
20 - 2006 - Digitech Bad Monkey overdrive, bought at Music Live 2006, a guitar gear convention in Birmingham. Also bought a BOSS NS1 Noisegate at some point.
GAS has gone, had everything I needed/could afford - End of 2006.
26 - March 2012 - Cornford Hellcat combo. ooops.
I would love to get back into the GAS mode as it was fun to be engrossed in the world of guitar equipment but I lost the bug a long time ago, the Cornford was something I had wanted for a long time. I do have to buy a pedal board/power supply soon, and I am thinking about putting a graphite nut and some locking tuners on my old squier. I'd like to replace the neck and middle pickups too but that would be too expensive right now.
