I purchased a 6505 MH a couple months ago - and I liked it. It did what I expected, but the more I played it, the more I felt it was a bit of a one-trick pony.
During the process of choosing the 6505 MH, I also looked at the Laney Ironheart IRT 15, but passed.
This Ironheart 60H showed up in a Facebook group I belong to - the owner was looking for a microhead in trade. I added a little cash and we made a deal.
The IRT 60H is a footswitchable 3-channel amp with a built-in boost and independent EQs. It's actually two channels (rhythm and lead) with a switchable clean channel. Some of the pots are push/pull for additional tone options. I'm going to explore more of that this weekend.
The built-in attenuator will take the amp from 1< to 60W, so it still works for my office play.
Cleans are damned decent... much better than the 6505 MH, but that's no surprise. Frankly, I didn't expect really great cleans out of the 6505. There's a lot of room to play with tone once you switch out of clean. Add the Badass Overdrive, and you have pure win.
So far, I've discovered that this amp is very sensitive to pick attack and even with OD, nothing gets mushy or fizzy. I was pleasantly surprised. Plus, I'm playing it through my Mesa 4x12 and it's loaded with V30's so that doesn't hurt.
Anyway, I'll play this more over the weekend and let you know what I think.
