When you first wrote this last month I was optimistic. Silly me
So... 9 days after GC charges my credit card I get a call that a combo is in if I want to buy it. I remind them I bought a head, I don't want a combo too. I took this opportunity to ask when the amp I paid for might be in. The salesman then gets the great idea to order one from another store

I agreed that we've waited long enough without ordering one that ordering one soon would be a good idea. He calls back later that day and tells me the good news that he ordered one from a local store and they'll ship it out the next week
So today it comes in

(short lived) so I go to the store to pick it up. When I get to the counter there's a LMK II in a beat up box on the counter with the cord hanging out. Startled I asked is this mine? Turns out someone else was returning one because they told him it will work in Europe but it really won't. No, mine was in another box so we opened that. In between a few thin sheets of foam was tossed a head, nothing else, no cord, no manual, nothing but just the head which was scratched and clearly used. I was cheerily informed that I'm getting a floor model (Yippee!) So I mentioned that when I paid for this 2 weeks ago I was told I would get a new one. Now a bit less cheerily I was informed that this was a take it or leave it deal, they will not lower the price on this used scratched floor model so I could either take it as is or get a refund. Another salesman joined in noddingly and confirmed there was nothing they could do and I'll just have to take the used demo at the full price of a new model.
It was at this point I pulled out my Uzi and sprayed the store with bullets... no wait, that part was just in my mind, I think what really happened was I asked for a manager.
Fortunately the manager agreed with my assessment that this was total BS and offered to let me take home the used amp, get me a new one from Italy (apparently there are none in the country) that we'll swap for the old one I have now and pacified me will a generous helping of swag from the showroom floor. ETA on the new amp is a month or so, maybe, no one really knows.
And Peter, I think you got passed your buck back
But now that I actually have one in my hands and my blood pressure has gone back to normal I have to say that so far (no loud volume tests yet) the amp is meeting all the expectations I've built of it. The simple EQ works great for my tastes. I find the amp strongly colored but it's a hue I like and I'm not one of those people who gets offended if an amp improves their tone.
I hope to get a new one of my own some day.
