Crate produced a genuinely genius product: The Powerblock.
Less than 10 lbs, over 100 watts, could be run in Stereo, and didn't sound terrible. It was a gigging musician's answer to prayers for an emergency back-up amp, and if you live in a city where you take mass transportation, it solved so many logistical problems that it was worth it's weight in gold.
Seriously: the Powerblock was a stroke of genius.
What did Crate do?
They discontinued it.
