I've acquired a fair bit over the years...

Guitars

Ibanez (Love 'em)

JEMs - BFP, BRMR and GMC
JSs - WH and BTB, and a 540 Radius
RG - 770DX, 550, 320FA
Universe UV777
Also a 540s - Sabre style

Others

Fender USA standard Strat and Tele
An old squier strat
PRS Custom 24
Gibson SG custom
Taylor Acoustic
Washburn Acoustic
Warwick 5 string bass

And a few others - I've only ever sold 1, and regretted that ever since!

Amps

Laney TT50H + 4x12 cab
Cornford Harlequin
Vox AC15
'Smokey' cigerette pack amp (Camel brand!)

Pedals / effects

PODxt Live!
Boss DS-1 Distortion
Ibanez TS808 Tubescreamer
BOSS Harmoniser
BOSS Delay (DD3)
Digitech Whammy
Morley Wah (Bad Horsie 2)
Little Alligator volume
BOSS TU-2 tuner
BOSS Compressor
Voodoo Labs Pedal power II

Looking at the G System or Rocktron at the moment... I'll get there, but fear change ;)

Miscellaneous

Roto-sound 'Pinks' 9's for the JEMs
Roto-sound 'Yellows' 10's for the JSs
George L & Van Damme cables
Dunlop picks 3mm
Levy's straps
G7th Capo
Roadie Rench
hair bands to deaden strings for tapping

And all sorts of other stuff... I use an edirol soundcard, Tannoy monitors and a behringer desk for recording into my home-made PC.
