does anyone use it on an alder guitar? how does it sound on clean tones?
Yep, in an alder bodied (maple neck) Charvel So-Cal Pro Mod.
like this one.
So far, mine has 2 mods to it; (3 if you count the pickup change) a push-pull volume knob, to split the Air Norton (neck) and a D-Tuna. Planned mods are a Floyd Upgrades big brass trem block and a brass trem-stopper.
Anyway, I like its clean tones as far as humbuckers go. It's quite balanced and definitely not muddy/choked. I think, clean, it comes quite close to the clean tone of a Duncan JB.
But because of the higher treble content of a JB I wouldn't go for it in an alder/maple guitar. I have tried a Duncan Distortion in that guitar once; super tight and punchy. Ultimate tone, were I to play late 80's/early 90's thrash only (think Kreator meets Dark Angel).
The Norton does metal well too, but just less 'extreme' than the DD. I like a more 80's hard rock/heavy metal tone for this guitar, since it's my Adrian Smith-axe for a Maiden tribute, so nice match. (yes, I'm aware that AS used Super D's)
