This speaker turned my pro Jr into a giant

I couldn’t be happier with this speaker in my vibro champ reverb build. It takes the boxiness away and makes it feel like a profesional amplifier.

Ive now tried out 8 different speakers with the vibro champ and can recommend this and the alnico as the best matches with my Stratocaster. They both have the vintage fender feel without the treble harshness

I bought the midnight 10" for my current BF Princeton build (from scratch, not a kit) but I wanted to hear the speaker. I have a generic 2 x 10 cab, so I disconnected one of the 10's and installed Jupiter's Midnight. I built an all octal Fender Super 5F4 (if memory serves) head and so far, it sounds best with my 4 x 12 cab loaded w/greenbacks, largely for there high end. Tried this head with the now 1 x 10 cab and it's magical. The best this amp ever has ever sounded. I tried a bunch of speakers, including a Celestion Creamback 90w alnico. I love that speaker for lots of things, but the match of this circuit and that speaker...chef's kiss. Modern Vintage meets Modern Vintage. Can't wait to try it with the Princeton Reverb build. Thank you, Jupiter!

Great speaker, sounds wonderful in my vintage 1964 Princeton Reverb !! Thank you!

Amazing replacement speaker for my print and style amp.
