OK, circling back around (with apologies since I'll probably post about 5 times in a row...) Again, this is minutiae - look away if that's not your bag.
I loved the 2nd HR they sent, just like I loved the 1st one, but I never would have shaken the sense that something was off with the PT. I had to leave town on vacation the day after it arrived and I just didn't have time to screw around with it. And plans to visit Atomic were certain to confuse things even further.
Arrived at Atomic, found the 100H, and it sounded very similar to the HR overall. If anything the H is a little smoother and darker and easier to dial, while the HR is a bit more versatile and therefore a bit fussier. Maybe? (More on this in another post.) I didn't buy anything on my first visit, but as the vacation neared an end, I mentioned to my wife that there wouldn't be time to go back, and
she insisted I call to see what they'd do on price, and then repeatedly insisted I go buy the thing, even though we didn't have room in the car for it, and even though I was hoping to be halfway to NY by the time Atomic opened.

It was like a weird "duck season wabbit season" scenario where I was somehow arguing against buying myself an amp. So I bought it LOL.
Atomic were
extremely easy to work with. I called and asked if there was any wiggle room on the price, and the guy said, "Always." Then he ran around the store looking for the amp and couldn't find it. (Sounded like he was going to have a heart attack LOL.) Told me he'd look into it and get back, which he did 10 minutes later. I offered $500, and he said "Sure". Went the next morning, stuck all the luggage in my kid's lap

and wedged the amp in the trunk.
I was really worried it would have the same transformer buzz once I got it into a quieter space, but it's powered up right now and dead silent. There's definitely something not right with two HRs I've tried.
So now I have to decide whether it's worth trying a 3rd time to "upgrade" to the HR, or whether to just get my money back. I do think the HR has a wider variety of voicings, and better means of accessing those voicings (between MIDI control and the Lead 1/Lead 2 and Clean/Crunch switches being more effective.) But that would leave me having to sell the H... and I hate selling stuff. (The nice thing is I'm not in all that deep even having purchased both amps, and now I have the H to hold me over if I have to go without the HR for a while.)
As for GAMANDA, FedEx sent me a survey asking how they could "serve me better", probably in response to my 1 star review. I mean, FFS, begin with delivering shit before you report its having been delivered, delivering it to the right town, and not drop kicking it off the back of a truck when you do.
