Why Soi-tenly.
1st I use an Epi 410UL for my medium to large club gigs. Don't need an extension cab.
2nd I use a Berg NV215 for large or outside gigs. Don't need and extension cab.
I am interested in a small tote along cab for rehearsal and small gigs that is a 4ohm to get the most out of my ThunderFunk which to me isn't great with a non-efficient 8ohm single. IMO/IME.
I have been using my Berg HT112 for quite a while with the TF and it's really just OK. The little Berg can take alot of power and I usually have the TF pretty cranked. I'm not unhappy with it, just always looking to step up is all. I really love the TF and I'm also hoping Dave Funk will come out with a higher powered version. I really don't want to do the slave amp thing either. (
I just sold my CA9 which was without a doubt the best most powerful pw/amp I've tried)(just way too big and heavy and I hardly used it)
I just received my new out of the box Mark Bass LMII last night. I am actually trying it out today at a company sponsored function with my Company Band. I will be using the LMII and the HT112 no PA support. This is exactly the setting I want to test it in. I tried it a bit last night and it's not better than my TF, just different. The short testing brings me to the place were most everyone else is on the LMII vs. the TF. It's flat setting has a bit more low mid thickness to it but not as punchie as TF. I'll report more later. I spent a few moments with these two amps into the 410UL also. So far, I pretty much prefer the TF, although the MB sounded very good. It's really a quite tweakable little amp. I'm sure I can find some very useable and likeable settings no matter what I plug into. Only thing ...both are 500w amps so it's kinda redundant, but right now I feel I will keep both. I'm hoping the LMII will be a better fit with the Bergs hence... I won't be needing another cab for awhile... yeah right.
