I purchased the block 800B as a backup unit because of reviews and ICE power section, I’m very disappointed it only has 300 watts of output power at a 4 ohm load, I compared it to my Aguilar Tone Hammer 350 and I had to turn the gain and volume to max and it still isn’t as loud, very disappointing.
And to return the item you must first take it to your local customs office have it checked, cleared and stamped, which is over an hours drive for me, then you can mail it back.
I think this particular amp mistakenly has the 300 watt power section installed. And I’m not sure they’re still using the ICE power section for the Block 800B at least they’re not saying that on their description like they do for their 300 watt version.
