Rat Bastid you surtunly sound like you know your stuff. If you've got any pictures of your current or past guitars I'd love to see them, espicially your customs. And I have to say I couldn't of put better the descriptions of the effects better. I have to say I'm completly used to as you say "guitar geeks", my dads an absolue nut. I posted earlier some of the stuff he keeps locked up.
Well Koolsax IMO (which isn't probably the best one), but I've just got a Zoom 707 Mk.2 pedal for my birthday. Real smart piece of kit, not the most rebust thing I've ever seen, but still good for a muck about. I paid about £100 for it (I don't quite know what that is in dollars) but it has:
Drum machine,
6 types of Wah-wah
Chourus,
Reverb,
Lots of types of distortion,
Delay/phase,
Lots of types of overdrive,
about 9 other different wierd kind of effects, like jet, wind, violin (basically a delay) and lots of others.
I can record riffs, play them and play over the top of them.
I can create my own effects. There are tones of features. The only down side to it is I can't really use it for performances, because ot comprimises the sound, it isn't at all robust I've known freinds to break there's very easily. I just simply plug it into my amp and plug my guitar into it and it allows me to change the sound of my guitar.
But it all comes down to as what Pako made a very good point of, which is finding your tone, or looking for the right tone. My pedal is great through my little practice amp (a 15 watt Squire SP-10), but through bigger amps the individual and great tone (IMO) is lost. Thats why you want to be very careful with choosing a pedal. That's why instead of a pedal you may want to possibly consider buying an amp for built in affects. For example I was in y local guitar shop the other day and looking at a Marshall MG50DFX (50 watt). It has built in effects, and it comes with a special pedal for these. This will save you from getting a seperate pedal. I also have some freinds who have taken this option and haven't regretted it since.
Yet I suppose in the end it really comes down to how much you want to spend or people want to chip in towards it, whatever.
If you do want a pedal, particular effect etc. then I suggest BOSS. My personal experiance with people I know with them is that they generally are reliable, sturdy and good pedals, perhaps some of the best you can get. Though they can get pretty expensive, and generally when you buy a BOSS pedal it usually has just one effect on it. Though thanks to the way they're designed you usually combine one pedaly with another one or many others. E.g. you could get a boss wah-wah pedal and a BOSS overdrive pedal and combine the two. You could also combine a BOSS pedal with another make if you wanted. BOSS's tend to be quite expensive though, but yopu pay for what you get in this case (they have a metal casing which can stand up to a pounding).
In the end it's up to you what you're looking for, just have a look around and if you have a guitar shop near you go in and ask to have a look a listen and even try the pedals. I know that my local guitar shop is very willing in letting me try guitars amps and pedals etc.
Hope any of that helps and sorry about the huge rambling.
