to be totally honest it’s something you would have to try, the colouring is very slight in ‘normal mode’ and a fair bit worse in ‘strong’ mode. …. but it seems to vary a lot in everyone’s set ups hence the different reviews.

…but I’m suprised you are hearing bad buzzing with the amp clean are you sure a ground wire hasn’t come disconnected somewhere in the guitar? …

I’ve never worried about the ‘fender spacing’ thing either, in my experience it makes little or no difference, most companies don’t even do different spacings on pickups… you know it’s only a 3mm difference from the centre of the first pole to the centre of the last? It’s not as simple as fender needs F-spaced either.

“F-spaced pickups measure 2.01″ (51 mm) center-to-center from the first polepiece to the sixth. Standard-spaced pickups measure 1.90″ (48 mm). Although some players believe that F-spaced pickups are only for the bridge position of tremolo bridge guitars, many guitars with fixed bridges (including late 1990s Gibson Les Pauls and Epiphone LPs) should have F-spaced pickups in the bridge position. Most tremolo equipped guitars that have a nut width of 1-11/16? (43mm) or more should also use an F-spaced pickup in the neck position. If you?re replacing a bridge-position pickup and you’re not sure what your string-spacing is, it’s usually better to get an F-spaced model. It is not necessary for the strings to pass exactly over the center of the polepieces for best performance, but it is wise to avoid a situation where the E strings are sitting completely outside of the outer polepieces.”

I’d think a P90 was a P90.. I didn’t even know that they made them with different spacing.

if you turn off the lights and all other electrical equipment, and plug your guitar into your amp at loud volume does it still do it? It might be worth going through it just to make sure it isn’t something else like pedal power supply or whatever.

take your guitar and amp to the music store and try it,
