I had the chance to play in church yesterday and was quite disappointed by how I sounded and I don’t know exactly what was different. The amp I used was a darkglass infinity 210 combo. By itself it can put out 250/275 watts. The bass used was my Dingwall Droc 5 string. While we were practicing I was told that I was too loud and my speaker was rattling. I never heard a rattle but I turned down. My master volume wasn’t at halfway either. I’ve kept it at that volume since I’ve had the amp and nobody ever complained while we were practicing. It was time for us to play and the only thing different was two backup harmony singers and the congregation. I could barely hear myself. I turned myself back up halfway again and I felt like I could barely hear myself. My guess the extra vocalist may have drowned me out. The acoustic rhythm guitar player is playing plugged up to a 15 watt amp now. That may have done it too. The last time we played at church I used the same amp with an 18vt active bass and didn’t have this issue with the volume on the amp at the same exact place. If these two women are going to be a regular thing with the group, do I need the 210 extension cabinet to go with this combo? I had been looking at the Gallien Krueger mb 212 combo. It’s rated at its full 500 watts. I want a combo amp that can handle these situations and the Gallien Krueger mb 212 looks like it can do it. The combo amp is lightweight and easy to load in and out. I know the issue isn’t the Dingwall Droc. I know what that bass is capable of.
