Re: My take on the Peavey Windsor head...
OP "I think I may see where a lot of the hate lies with this amplifier. I've seen it described as a "Marshall clone" or a "JCM 800 or Hot Rodded JCM 800" clone. My opinion is that it is far from this, and when people buy this amp expecting that, they get what they didn't want, so of course...it sucks! Because if that is what you're expecting, it is gonna suck. That is what I was expecting, but here's what I got instead."
Now I will quote what other people say about the amp. Just read the comment section bellow the video.

This is one of the best brown sound replications I've seen on youtube! Nobody will ever nail it perfectly, but this is suprisingly close. hot damn!

Dude your playing is so sick and the tone you got for the Windsor is amazing. What are your settings on the amp?

I cant believe it sounds so good with bass at 2, mid at 1, treb at 1? Wow. Awesome sound and playing. Thanks!

2:20 is so nasty, but the whole thing, the tone, the playing, just the amp sound, all is exactly like Ed. phenominal!!

Canned Dirt
even halen coodnt to get it to sound like off the album like this twice
And I could go on and on. I could easily find lots of similar opinions on other forums. Do you see the obvious contradiction? So, I would like to know, what exactly in the Windsor sucks so that people hate it? If I new I might be able to help the others to make it sound good and as close to the JCM 800 as close can be.
