I had a '65 BF Princeton Reverb with an EV10M speaker. I bought it from a buddy for $250 back in the 80s. The amp came with its own Anvil case. It was louder and cleaner than you'd expect with the EV. I ended up selling it back to my buddy for what I bought it for. He missed it and I was living in an apartment at the time and the amp was too loud.
