I've only been playing 4 years so I'm quite embarrassed by this list, mostly by the number of effects pedals that I have gone through!
The Amps, and to some extent the guitars have been a result of starting to jam with bands, then gigging. A bit of trial and error in regards to what was easily transportable, loud enough and what comfortably fits into a tiny stage space!!
