I've owned YCV20, 40, 50, and 80's. They were all very god amps. They took a lot of abuse and sounded great. My favourite was The YCV50 Blue. I had the matching 1x12 extension cabinet. I played straight into the amp with no pedals. With the master volume I could get a good tone for any venue. t home and small venues I didn't use the extra cab. Next was the YCV20. It had the nicest breakup and was loud enough for most venues but it wasn't as versatile as the YCV50. The YCV80 with four 10" speakers was a beast. It was a Twin killer with a lush reverb. Strangely, as it was the most powerful, at low volumes it was the best of the bunch. Live it needed pedals to sound it's best.
