As in your guitar rig, or collection of synths etc, or do you see a new piece of kit and think it would sound better than what you currently have?

I've been using a fender bassman head at the studio recently and really want one, it sounds sweet with my jazzmaster. However, my guitar tone usually is pretty good, got an Orange Dual Terror which is very easy to get good sounds out of, and sometimes I think I'd be daft to want to replace it.
Also made the mistake of looking on the Matamp website last week.. argh!
