Compact, Open-back Cab

The Friedman Amplification Small Box 1 x 12-inch open-back guitar speaker cabinet is the ideal partner for Friedman's Plexi-inspired Small Box tube amplifier head. This cab delivers a smooth sound with the airy sonic signature of its open-back design. Yet thanks to the Small Box cabinet's single Celestion G12H Redback speaker, it sings with vintage character and a smooth top end while offering plenty of low-end thump. Take it from guitarists at Sweetwater: the Friedman Amplification Small Box guitar speaker cabinet will make you a believer in getting huge sounds from small packages.

Friedman Amplification Small Box Features:

  • Compact cabinet that's ideal for gigs where space is an issue
  • Mates perfectly with Friedman's Small Box amp head
  • Open-back design offers detailed tone and a wide sonic spread
  • Rugged Baltic birch construction can handle heavy touring
  • Classic looks
  • Handles up to 150W of power
  • Celestion G12H Redback speaker offers plenty of punch and a tight low end
  • 16-ohm impedance

Reviews

Friedman small box
Excellent cab! Paired it up with my JJ junior combo, sounds great! Can't go wrong with a Friedman,Thanks to Adam hunter for helping me with my decision, he's always ready to answer questions, thank you Sweetwater for your excellent service!

Amazing! Fits the SmallBox head perfectly!
I bought a SmallBox earlier in the year and wanted a 1x12 to match for smaller gigs. Friedman amps and cabs are flawless works of art. Boutique Amps Distribution has some of the absolute best tolex work and their cabs are built like tanks with the best materials. I own a DirtyShirley 40 with matching 1x12 so I ended up swapping the creamback to an alnco cream since I didn't need 2 1x12's with the same speaker. Man, such an absolute incredible sounding amp and cab. Couldn't' be happier and SweetWater is amazing as always.

Awesome
Fits perfectly on with the smallbox head. The cab is incredible, sounds as large as my 2x12"s. I"m blown away!
Big thanks to Jozy Franco for all his help with my order!!!
Fits Perfectly
I was somewhat concerned about purchasing this extension based on the previous review, but after receiving this, along with a 2018 model Small Box head, I can assure you that they match perfectly in every detail. The size, tolex and piping all match the head exactly. It both sounds and looks perfect.

Doesn’t match with the Smallbox head
Unfortunately.....this cab doesn"t fit my 2014 Smallbox head. It"s the same size as my Dirty Shirley cab for my DS40 head. The Smallbox hangs over both edges by about 3/4". It sounds sounds good, a little on the smooth side but that"s the Creamback 65 for you....dark sounding greenback. I can only assume current SB50 heads are smaller in size to match this cab model. How about we make the cab bigger not the headshell smaller to match?
