I found the Big Bang to be overly warm. Warm to the point of sounding unfocused, if I can say it that way. Not muddy, just unfocused. I found this underlying weird vibe going on with the overall sound no matter what I did with the EQ. It's like this new baked in warm/weird thing going on. My LMII never had that vibe. I will say that little sucker is powerful and LOUD...it's definitely got cojones.
I thought of the TH500, I've used one with my Baer in the past. I was a little worried that it might be too warm, and not clean/tight/punchy enough. And when I say punchy I mean throwing out a focused articulate note, even at higher volume. I guess tight/punchy can be the same thing to me. I could always order a TH500 from one of the big online retailers for a test drive and return it if need be. Part of my problem is I'm evolving and actually starting to find my own identity as a bass player, and I have the idea in my head, the sound I'm trying to hear, I just need to find the amp to help me get there. Bass I'm good, cab I'm good, I think.![]()
I've never heard the Big Bang. Interesting. It is clear from the reviews that it sounds different than the LMIII. You might want to try an LMIII again. Since they upgraded to the full featured DI (versus the II), that head is pretty amazing for those wanting 'warm, even, clean' in a lightweight package. I feel it lines up VERY well with the Thunderfunk 750a at 4ohms. However, you don't have the ability to really punch up the low mids (not really necessary on the CN212 IMO(), and the LMIII is voiced a bit more 'open and even' than the very mid punchy TF heads IMO and IME.
I'd just get that thing out of a rack (if you have it in one), spring for the cabbage case, and get a good cart (like the kart-a-bag 600) where you can just set that head on the top of the cab and wheel 'er in. The TF750 is a GREAT head, and the EQ is quite impressive.
