I love going round and round on this subject with you because you put up so many arguments against what I say about the LMII, even though we both agree it's the best solid state amp going, and even though after all this time you still don't feel me at all.
OK, so here's why you can't push me back on this...From the time I was 17 until I was 37, the only two gigging amps I owned were a V4B/810 and an SVT/810. Had an Acoustic 136 combo back then, but it was relegated to practices because it was vastly inferior to my Ampegs and not much lighter. So I come from a tremendous background of using tube amps for 99% of my gigs.
You, OTOH, come from a background of using nothing but solid state your entire career. You have said many times that you hate tube amps, and so your entire frame of reference is based on almost all solid state with sporadic tube amp usage, if at all.
There is a certain tonality that I associate with tube amps, especially Ampegs. I can't put my finger on it, but I know it when I hear it. In the 10-year span that I quit using tube amps regularly, and before I tried the LMII, I have tried every major solid state and hybrid amp out there with the exception of the Aguilar DB750. Do you know how many of those amps gave me the tonality I was looking for? In the words of Dean Wormer in Animal House (and Eric the Midget from the Stern Show): ZERO...POINT...ZERO!!! Closest I ever got with with an SWR SM-500 and SM-900, but even that didn't sound anything like what I wanted to hear. It had certain aspects, but it was very much a solid state sounding head.
The second I tried the LMII, I knew it had the tonality I was looking for, and many AB tests against my B-15N confirmed it. The LMII is the ONLY SS amp I've tried that has it, save for the other Markbass models based on the LMII's circuitry. Yes, it's very clean, but so is an unpushed tube amp. And while there are similarities in the tones of a clean tube amp and a clean SS amp, I can easily tell the difference blindfolded.
You say there's a quickness to the attack in the LMII that totally separates it from tube amps. I say you're mistaking overdriven tube amp mush for the classic tube amp sound. Ain't nothing mushy about my SVT at lower volumes. I submit to you that a tube amp at medium clean volume sounds a lot like an LMII at a medium clean volume. It's not identical, but it's about 90% there, which is a lot more than I can say about any other solid state or hybrid out there that I've tried, even Ampeg's. And it sure seems like quite a few people who are used to the Ampeg tube amp tone agree with me. Not all of them, of course, but enough to know that I'm not just hearing things.
Now if you REALLY want to nail Ampeg tones from clean to screamin' in the inexpensive SS department, the Sansamp VT is a better way to go because it nails the tones and it's $150 new. But if you just want a clean Ampeg tube tone and you want it in a 6 lb. SS amp, I will heartily recommend the LMII because as of yet, it's the only one I hear it in. Again, I won't say it's identical, but if it's close enough to keep me satisfied when I can't use my SVT or B-15, it should be close enough for most Ampeg lovers.
Your frame of reference is completely different from mine, and that, to me, is the beauty of the LMII. It can please someone who wants a good "modern" solid state tone as well. But even though I like arguing this with you, it does bum me out that you don't think I'm hearing what I'm hearing, or you sell it short by saying I'd hear the same in most SS amps. You don't have the background with Ampeg that I do, so you really don't know what I'm hearing that makes me think that. So next time, instead of pushing me back, maybe you should think about my extensive onstage time spent with Ampegs and realize that maybe, just maybe, I know what I'm talking about.
Either that, or you're going to have to put up with more of these long, boring posts from me

Peace out, my brother!
