Regarding the reverb, also go expensive. I think this is the second most important tool in the stomp-box kit. The high end reverbs have lots of different reverb types and the best ones really sound good. I know that "sound good" is pretty subjective, but if you A/B two reverbs on similar settings (like comparing spring to spring reverbs), one of them is going to sound BETTER to your ears. That's the one you want. I've heard great players talk about having two reverbs in the chain, one feeding the next, but when I've tried that I've only produced more mud. So for now, one reverb on the board.
Every day I get YouTube alerts telling me so-and-so is demonstrating a new reverb pedal, or a fantastic new multi-delay pedal, or a programmable distortion pedal, or whatever. And I go watch the demo, and it's some guy that is an amazing guitarist that makes the pedal sound unbelievably good. I just fell for it tonight, ! , again, and watched the Empress Effects Echo System delay demo (https://www.youtube.com/watch?v=BjcngtWVU1g&t=71s). Gotta have it!
And finally, the delays that I now have take quite a bit of practicing with to really understand what sounds they can make, and what settings will bring out the sounds that I want. I'm just scratching the surface. So, new working guideline: in an inherently complex environment, keep it as simple as possible.
