In the upper left is a 'Mighty Mite' single coil. Then there are 3 single coils. In the 'center' there are 4 'stacked P90s (two coils, stacked). On the upper right there is a 'humbucker-sized P90' in gold. On the lower right are a pair of dogear P90s.
While all but the dogear ones are slightly used, they're all in good shape.
The wiring on the 'stacked' ones may be counterintuitive, but when wired properly they do indeed mitigate the 'buzz' commonly found in the single coil varieties. By the same token, when the stacked ones are wired 'improperly', the buzz is actually more than a single coil.
Basically, when these arrived from the manufacturer, the color coding was unexpected. In the default wiring configuration, the buzz increased. Perplexed, I flipped the polarity on the 'other halves' of each of these pickups, and the buzzing was actually reduced from a stock P90.
These 'stacked' pickups may require a deep cavity, or they might be close to the strings. Anyway, when you can get them installed and working, they're actually fairly fantastic. YMMV
The 'Might Mite' is a mid-cost pickup, and could be said to be an improvement over standard P90s.
The 'humbucker-sized P90' sounds a tad 'metallic', but it does overlap with the traditional P90 sound.
The dogears were never tested over here.
Everything is as-is. The collection of mounting screws might not be an exact match, but the soapbar varieties (including 'stacked') do have screws. The gold-colored screws are missing, for attaching the humbucker-sized P90's mount to the guitar. The dogear mounting screws are also missing.
