I think as most people have said, Laneys really arent a "plug 'n play" amp, take everything you know about EQing and amp and throw it straight out of the window because theres nothing else out there that works like a Laney. I had my first VH back when i was 23 and i didnt like it, i found the features confusing and i couldnt get my head round dialling it in, 3 years later i bought another one and absolutely loved it, but it was on after i'd spent the time and got advice on speakers and the way the EQ works.
I found the Ironheart the same, i tested the amp pre-release about 18 months ago and the guys at Laney had it dialled in so well it absolutely floored me, but after tinkering for a few minutes i had got totally lost in the amp! It does have a lot of tone shaping features and the range of tones is quite vast but all of those tones are very Laney. Maybe you're not getting on with the Laney voicing? Its something that is an acquired taste and it isnt for everyone, but you hear that core sound in everything valve that Laney make.
As for the on-board boost, i've never come across the problem that a few forumites have, yes i have tried it maxed out on the lead channel with the gain maxed out and i didnt have a problem. I've found the boost really useful, especially at lower volumes. I think those experiencing problems may be pushing a lot of bass frequencies as well as gain and what they should remember is that the boost boosts all of the frequencies.
I don't get how people can't dial in an amp. It's not rocket science here folks. Maybe it's because I used to write machine code for CNC's where you're worried about 3D geometry and trigging out angles in 17 different planes and making it all work, but to me, regardless of how an amps EQ works it takes me about 10min to figure it out and dial in a workable tone.
Maybe it's because I've owned Boogie stuff for 20 years
