Teisco Gold Foil

Pickup features: Passive single coil
Impedence or other specs: Decent output, beats out my '86 Fender Jap Strat

Model of guitar or bass: "Sandtron" guitar. The logo is on upside down, so I'm doubtful. It's a Jag-style guitar with a top-mounting tremolo and 3 rocking switches for pickup switching. I use it for slide because the neck (neck trough body too) has warped beyond repair.
Position: all positions
Pickup being replaced: Original pickup
Other pickups on guitar: Another of the same
Artists using this pickup: Ray Cooder, I heard someone say one of Satch's guitars has 'em, but they could be mistaken. I haven't looked into it yet.
You musical style(s): Blues, country, jazz, rock, metal, folk, latin, whatever else.
Reason for pickup change: I didn't change it.
Although soon I will be taking the neck pickup out and putting it into a neat D'Angelico inspired thinline guitar I've been building.

Perceived output level: Bit more than my Strat, I'd say gettin' near 10k ohm.
Tone: Whatever you need. The pot (normal 250k one) really chages it well, from a bit trebbly to ballanced, to nice deep bassy while never losing high-end definition. I <3 it.
Sonic evaluation: For clean tones, I either run it through a 200 watt Yorkville bass amp or a late 50s Gibson Skylark tube amp at low volumes. It sounds absolutely brilliant for country, blues, and jazz. Roll the tone pot down and it mellows out beautifully, you'd swear it was a big fat hollowbody, not the 3/4 inch wide piece of leftover shop class wood that it really is. For that real gritty balls-to-the-walls swamp blues distortion, I just plug it into the mic input on the amplifier for my record player. Absolutely perfect tone in the dirtiest, nastiest way. Only effect I use with this guitar is an older Ibanez tubescreamer for a volume/treble boost with soloing.

For which styles and positions is this pickup (un)suitable: I play a bit of everything, and it seems to be a good match for a few things. It really lends itself well to jazz, although I wish the guitar it's on right now wasn't near impossible to play it with. Decent country pick-up, not much twang I'm afraid though. The best blues pickup ever in my opinion though.

Comments: I'd definately buy another one. I might buy one anyways for my other guitars, wouldn't be the only pickup though.
I've been playing guitar for close to 5 years now, many other instruments for longer, and guitar-wise I own an '86 Fender Jap Strat, the "Sandtron," a reissue Danelectro MOD 7, a Simon and Patrick folk cedar model acoustic guitar (highly recomend that, too), a defretted Westone Spectrum IV bass, a Dean Rhapsody 12-string bass, and have a few project guitars I've been working on.
I absolutely love this pickup, especially for blues and jazz. Only complaint is since it is top-mounting and a fairly awkward size, it would take a fair bit of effort to put it in a guitar. If you have the patience to do it though, you're in for a treat. It was a real stroke of luck getting this pickup, it was on my first electric guitar. I bought it because of it's slick looks, and luckily enough ended up with a real kick-ass set of pickups.
