Speaker - Jensen® Vintage Alnico, 12", P12Q, 40W
The P12Q is a lower power sibling to the P12N, with a smaller voice coil and a vintage steel basket, nicknamed the “hot dog” or “sausage” because of the shape of the openings in its basket frame. Warm and balanced sounding, with a nice bite in the upper midrange, it is a very interesting allrounder, for many different applications from the traditional country and jazz tones to the more aggressive rock and roll and blues application. Typically it was found in ‘holy grail’ amps such as the vintage Tweed Deluxe and other similar models as well as the Ampeg® Jet, Gibson® GA-20 and many more.
Guitarist Description: Very warm, mid-focused bite with clear bright highs. When presented with overdrive distortion it remains well balanced.
- Lows: Loose
- Mids: Firm
- Highs: Smooth
- Overdrive: Edgy
