This is a vintage 1966 Univox U45B combo amplifier. It is all tube with a unique compliment of 6X4 rectifier, 6BM8 preamp, 6BM8 power, and 12AX7 tremolo. It pushes approximately 10 Watts through a single 12" Jensen speaker. This amp sounds really good! Unbelievable tone: clean when you want it to be - and some of the best natural overdrive we've heard in a looong time. With 3 inputs, you can even jumper two of the jacks for an extra blast to the preamp (check out the 3rd section of the demo below to hear it). Simple to use, with only volume, tone, and tremolo (check the 2nd section of the clip below)! Tremolo is foot-switchable, although it does not ship with a pedal. It is all original with the exception of some capacitors and 12AX7. Still has its original 2-prong AC cable. It is in fantastic cosmetic and functional condition.
