They are a pain in the *** to work on for someone who doesn't work them everyday like Mesa in Petaluma. I'm sure when Mike Bendinelli retires (which is supposed to be soon) he will have all the Mesa Service work he can handle if he wants it. Hopefully he will continue on his own.
The MKV 90W Combo is a very nice amp. I find it actually easier to tweak up and less temperamental than my faithful MKIV-A.
But I still prefer the MKIV-A. If I find another in as good a condition (or even close) as mine I will buy it and sell this MKV. I find the MKV 90 to my ears a little too polished/refined sounding compared to the MKIV-A here. Kinda like how my Friedman Small Box 50 is compared to an actual Marshall JMP 50 MKII. Or how any of my Wizards are compared to an old JTM45. The JTM45 will sag and Wizards sag very little if any unless they are dimed.
Mesa must have tweaked it that way because of all the bitching about the MKIV. I find the MKIV just a bit more present, immediate, and "in-your-face" in all three channels. I notice the extra drive controls on the MKIV, absent on the MKV. Must have been too much bitching from those having a hard time with it.
The Stiletto Ace is another out of production Mesa I wouldn't mind having.
From what I have gathered, Mike B mostly works on the older Mark series amps sent back for repairs and possible modifications. He definitely can't be the only tech working there, and I'm sure that there are others working there who do a fine job repairing their current amps and such. As they build the amps and repair them, they are most familiar with the issues that they usually have, and unfortunately sometimes certain batches of LDRS and other parts end up being substandard, which isn't found out until 5 years down the line.
The Mark IV is a great design, but unfortunately not the most intuitive. Most seem to also not be a fan of the "Rhythm" channel. The multitude of rocker switches and push pull knobs can definitely be intimidating, kind of like an 80s-90s Rivera amp, where almost every knob pulls out and does something. The Mark V is of course intimidating in other ways, with the ability to really customize the power section and how it responds.
I have a Stiletto ACE Combo, and it definitely is a great amp. I am however not sure that the choice of a Vintage 30 was really the best one for a Bright amp like the Stiletto. I installed a Scumback J75-LD 65Watter and I find it to be much more versatile and better sounding, especially on the crunch mode. Some may like it, but to get a decent sound on Crunch I had to turn the treble and presence almost off, and only run it in Spongy / Rectified mode.
