I've recently started playing an Ampeg SVT 2Pro through a Berg NV412 and it absoltuely kills for that new vintage, "tube amp through a big sealed cab" vibe. I'm very happy to be back in the Berg family, to say the least and am considering getting a Berg AE410 for some added versatility and portability when needed. I'm wondering how the AE410 would sound with the SVT - I've heard that cab described as tight with good upper mid presence, which sounds like an awesome match. Would be nice to have the ported cab\tweeter available when needed. And though I don't mind lugging the SVT, our practice space is down a flight of long, narrow stairs and the portable option would be nice. Thoughts?
