So I'm trying to start a drum and bass band with my friend and I'm trying to run a bi-amp setup for a huge, full sound. I already have a Traynor YBA-3 (which is great) and I wanted to get another tube bass amp to pair it with. Coincidentely, I found a seemingly rare Ampeg SVT-100. There's not a lot of information on it (only about 100 were made...?), but I thought the specs would probably be pretty close to my Traynor and the price was good so I went for it. I just A/B'ed the two amps, and the Traynor is WAY louder. The Ampeg isn't quiet or wimpy by any means, but you have to get past the halfway point on both the gain and master volume knobs to get into what I consider somewhat acceptable territory. The Traynor gets just as loud, if not louder at like 1-2 (7:00-8:00). At the halfway position for the same knobs its REALLY REALLY loud...which is good I guess what I'm trying to figure out is: is this normal/expected? From what I understand they are both supposed to be around 100-ish watts, but are there other factors that would contribute to volume? Part of the problem is I can't find the specs for the Ampeg, but based on what I found I thought they would be pretty close in the volume dept. (if anyone can find specs or a manual that would be great) I'll start there, but assuming there is nothing wrong with my amp the next question will probably be how can I make it louder... Also just for reference I was using a Bergantino NV610 for the A/B test.
