Just got a U-45B in pristine condition. Offshoot of the Univox brand. It's a 12 watt amp with a speed only controlled tremolo. Hooked up my BD2 bluesdriver pedal to it an oh my gooood!!! What a pleasant surprise for under 200 bucks. I will stop looking at all these boutique amps at 1 to 2 grand I've been checkin out and start looking for old cheap tubers. What a treat!
