I just sent my Mark III off to Mesa Boogie. It's well overdue for some routine maintenance, caps, etc, but rather than do it locally, it's going out west for a full overhaul and a III+ upgrade from Mike B. I'm going to be honest, not sure why I'm even doing it as I've always loved the tone of the amp, but from what I've read, it seems like it would suit the tones I like from the amp. Anyone have any experience with the III+ mod?

I have thought about it. But I haven't done it yet to my 1989 green stripe. I should send it out to them for a run through. But, I love the way it sounds as is. So I doubt I will bother with the mod.

some stripes benefit from it more than others... it makes a big difference on black/purple stripes... on the later ones (red/green/blue) it's more subtle...
if you like the way your amp sounds I'd say just do maintenance and leave it unmodded.

My personal favorite MkIII is the stock black stripe.

Based on what I've read on various forums and what the guys at Mesa told me over the phone, the III+ mod smooths out the lead tone, taming some of the high end fiz and brightens the clean channel a little. My Mark is red stripe and while it's fantastic, it can be a bit over aggressive, so smoothing out CH3 and taming some fiz is a good thing. I've talked to a few people who have done the mod and they swear by it. There is a III++ mod too, but that is just pushing the gain up on top of everything else and I don't see the need for that at all. Anyway, long story short, sticking with the plan and going for the III+ mod. I love the amp, but when recording solos, I do tend to favor my Diezel Herbert as the lead tone is so smooth on that thing. Figure Mike B isn't going to be doing this much longer, it's now or never. Dropped the amp off at UPS today, so it's on the way.
