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.
I just bought a Jensen P12Q for Fender Deluxe 57 reissue. I had a P12R in there for the last 7 months with which i have been very pleased. I think now that this P12Q might be the new replacement. In comparison, it has a sweeter and smoother treble, mids are about the same and the bass if anything is slightly warmer. Not really a huge difference at all. The P12Q adds a little more character or color while the P12R is a more neutral sound to your guitar's own tone. Both are great and this is a new speaker but I'm sure it will really shine when it breaks in just as the P12R did.
The P12Q is excellent.
I've been playing guitar for nearly 50 years and designing and building speakers systems for musicians for more then 40 years. I bought a new Trace Elliot Bass amp a few years back that had a Jensen MOD12-70. It ended up in my Fender Deluxe, exactly the sound I've been searching for for years. Now I've got another MOD12-70 and P12Q, they make all other speakers sound muddy (no not Mr. Waters). All my amps are being changed to Jensen. If it ain't broke don't fix it.
Well, finally my P12R fried on my 1955 Fender Deluxe. I had a gig so I put in a new P12Q. The amp has opened up more than I expected. My amp tech commented that he had to place the (57) at fifteen degree off axis to compensate for the increase in volume. I usually carry a Mesa Boogie Studio 22 with a 90 watt Black Shadow as a backup amp, but it doesn't look like I'll need it. You guys Rock!!
I recently fitted a Jensen P12Q into my Fender Blues Junior III Red Sparkle FSR and what a huge improvement over the standard speaker, which was a Celestion Greenback G12H which itself is a fine speaker but a bit bright and harsh compared to the P12Q which is much warmer and smoother in tone and breaks up just nice when driven.
Great speakers. Liked them so much I picked up a C12N, P12Q and MOD 12-50 to re-do three respective new amps to give them a more vintage tone.
