Re: Warm tone Vs. Bright tone
I've gone from one camp to the other and think they both have their place.
I've played strats for 30 years & cut my teeth on Deep Purple & Led Zep in the 70's. I have only recently started exploring the sounds possible with P90's and humbuckers.
In the early years of Stratdom I was a guy who played with major distortion, tried cramming as many notes into a measure as possible and played 90% on my bridge pickup. When I was young it was all about how loud and fast you could be. Very bright tone was where I lived.
About 10 years ago when I hit 40 years old (and finally had some money) I went on a "tone quest" and discovered so many wonderful variables: boutique amps & pickup makers, etc. Now I play with more feeling/less speed, no pedals, and using all the pickups on the strat and every configuration possible - with about 75% of my time being split between the neck p/u and the neck+bridge (tele) combo. WARM FAT TONE is what I most often strive to attain, with enough highs to capture & project finer notes, bends, etc.
I went from playing as fast as possible with mega bright "Ritchie Blackmore" tones to warm tones with bends more like David Gilmour. Still find a razor sharp strong bridge pickup + a thick warm neckp'up to yield the most possibilites... I've found good pickups set at the proper height as my solution to the "tinny bridge/muffled neck syndrome" that Blueman mentions as being common.
P90's are a great in-between that are (as Aceman recently wrote) "fatter than any strat and cut better than any humbucker..." They really respond to different picking & get nice and gritty when you dig in to the strings!
Newest quest is learning how to get the tones I want from humbuckers which after 30 years of single coils seem to be muddier, but with great powerchord and sustain possibilites.
Once you have all the gear purchased then there are TONE CAP's to experiment with. The variables and nuances never end - but at least tone caps are cheap. A .1uf paper-in-oil cap can yield a wonderfully warm tone when tone pot is fully open.
So now that you know my life story I can actually answer the question: I like Warm tones with a frosting of bright on top + a side order of a HornbySkews "TrebleBooster" pedal for when I want Brian May thick syrupy notes that hang in the air forever. (My one-and-only pedal...)
