The Hamer Phantom is a very rare and collectable guitar, built in limited numbers in the 1980s. It started out as a prototype, called simply the Hamer Prototype. It was special in that it had a very unusual three-coil pickup at the bridge. Some also had one single-coil at the neck.
It was based on a good-looking Superstrat shape, with the bass side horn being elongated and the treble-side shortened. It resembled a coupling of a Fender Jaguar and a Jackson Soloist.
The guitars usually had a scratchplate and Kahler tremolo. Some rare models had an ordinary humbucker at the bridge.
All the reviews I have read of this guitar praise it highly, and it is known as a very nice guitar.
One notable Phantom user was/is Andy Summers from The Police.
Phantoms are rare, but surprisingly inexpensive used considering the looks and quality of the build.
I saw two in Denmark Street recently for around £800-900, and I am sure they would sell on eBay for much less, in the rare event of one coming up.
