Peavey T-40 thread

So you actually have an insane number of pickup combinations available.Unfortunately only two of those sound good, the neck position and the bridge position with the phase switch selecting the front coil of the two.Anybody know if this the same with both production runs - i.e. pre/post '84? The older models with the toaster pickups had two magnets whereas the newer blade ones used only one due to a redesign - I got this from the T-40 forumChip Todd wrote:The original pickups had two magnets; one through each of the coil's bobbins. These magnets were ferrite material and were rectangular in cross-section and were stood on edge. There was a magnetic return strip of iron laid flat across the bottom of the pickup and magnetically attached to the bottom edges of the pickups. This iron kept the magnetic field from forming on the bottom of the pickup identical to the top field, so the field on the topside was greater than of that of the pickups like Gibson, (without magnetic returns). We used iron, as opposed to steel, as iron is more compatible with magnetism than steel. Steel won't remain magnetized as long as iron.The blade type pickup had two thin strips of plated iron arranged on edge through the bobbins, (which had to be redesigned with a thinner slot through the centers). The magnet was quite like the magnets of the early pickups and was held between the two blades. The magnet was laid flat, (not on edge), and took the position of the earlier magnetic return. We found the position of the magnet was more efficient, so only one magnet was used, with the overall result a stronger and better-shaped magnetic field around the strings.I use the bridge pickup in single coil mode with the phase switch up - switching it down cuts the output drastically (suggesting the rear coil is goosed?). Some of the settings are wildly different - I'd imagine this would equal back-breaking versatility for the contemporary wedding band who need to jump from Super Bass to Wonderful Tonight at a moment's notice...
