Hi guys! I have been using an Ampeg B2RE for a while (band owned, don't have my own rig for playing out yet) through an Ampeg HLF410. It sounds ok most of the time, when we play out I usually don't go through the PA, just use the stack to carry the room. This past Saturday we were playing a show and a few people mentioned a lack of bass being heard out in the crowd, I was having a hard time hearing my amp as well and tried to turn it up a little more (gain was around 11 and master was at noon) and just couldn't get anything extra. After a little frustration, I turned up the master to around 4-5oclock and the gain to noon... this helped a lot. So I guess what I am rambling about is, how am I supposed to set the master and gain on this thing? I have read that the best approach is just to crank the master all the way and use the gain to control volume? I had set the gain with the master all the way down and then came up from there in the past.... whats the best way to approach this? I am trying to use this until I can buy my own rig.
