I recently installed a P12R in my 5E3 deluxe circuited amp and WOW, it's THE SOUND I was looking for. Perfect clean and breaks up very nicely when pushed. I play slide and steel guitar blues through it. Thanks for getting it right.

I tried a P12R in a cab, which is made from an old piano and it sounds fantastic

I bought a P12R to go in an Epiphone amp, which broke down at a show. I'm going to scrap the amp most likely but I'm planning on keeping the speaker for use with one of those new Vox Nighttrains. I was very satisfied with the tone of the speaker. I also plan on putting together new cabinets with your Neodymium speakers (a 4x10 and a 1x15) to go with my Peavey Windsor.

I bought a P12R and put it into a vintage Fender Deluxe
Reverb amp. Really made a huge difference in tone for the amp. My pair of C10Q's in an open back cabinet produces the best tone around the block. You can't beat them!.

I am pleased to say that my choice of a Jensen P10R and a P12R Alnico speaker return the 44 year old Gibson GA-30RVT to its formal glory. The Jensen Vintage speakers give a very rich and warm sound, exactly what I was looking for, Thank You!

I play through a 1964 Fender Blackface Deluxe, not a Deluxe Reverb, a Deluxe. (Yep, the good sounding one). It is completely original except for tubes and a new Jensen P12R. There is no difference in the sound of the original speaker and the new P12R. I also use a 1965 Champ with a new P8R in it. Same deal...no difference in sound from the original speaker. If you are rebuilding an old low wattage Fender amplifier this is the way to go. These people totally nailed the sound of their original speakers. Thank you Jensen.
