Lou, whats a good price for a pair of Dragon I ?
Dragon 1's are rare to find for less than $400 a set. You'll see them for $350. sometimes. There's several on Reverb.
Dragon 2's are less. $225 -250. They have nickel covers and the neck pickup seems to be the same pickup as in the Dragon 1 set.
But the Dragon 2 bridge pickup is not the same as a Dragon 1. It's 12K, not 20K, and it doesn't have a ceramic magnet. It has an alnico 4 magnet like the neck pickup and like some '59 Gibson paf pickups. Different sounding pickup.
The two pickups in either Dragon set are magnetically out of phase and meant to work with that 5 position rotary switch.
With a 3 way switch you'll get a thin out of phase sound when the two pickups are combined.
With the rotary switch you never combine the two pickups as you would with a 3 way switch.
The middle sound is one coil from the bridge pickup and one coil from the neck in series so it forms a humbucker that sounds just like a middle humbucker.
If you want to use Dragons with a 3 way switch, like in a Les Paul, you'll need to loosen the baseplate of one of the Dragons, slide out the magnet and flip it to reverse the polarity.
Then it'll be magnetically in phase with the other and sound fine when they're combined.
