Yesterday I was looking at Rhoads Music site and I found this:
a. NEW 7.4k ohm Reissue toaster pickups - $90.00/each
b. NEW higher output toaster pickups, now out of production - $125.00/each 4 in stock
When a product has been discontinued such as the the pre-Scatterwound 7.4k ohm pickups, the price may be increased because of the rarity value; i.e., you can no longer get these new.
Sometimes, dicontinuations of a product lead to a decrease in price because the vendor wants to get rid of the product.
I suppose it depends on the outlook of the vendor...
