i had the LH500, which is the little brother of the LH1000. tonewise it was my favorite amp, and i found those simple controls to let me dial in a lot of variety. that being said, i'm a bass guitar player, not a standup player. i have a semi-hollow SRH500 that also sounded great through the LH500, but it's not the same thing, is it?
i finally sold my LH500 because it weighed almost 25 pounds, and for me that was a no-go. it's also physically larger than most non-tube amps. if you compare it to a GK fusion head, the fusions weigh a third as much and also have a tube. they sound great, but cost a lot more.
if you can get a good deal from your friend, what's the downside of trying it out to see what you think?
