I would be really interested what volume levels some of you folks gig at when 1000w heads are being spoken about.
I play in a pretty loud rock band, bass, drums, guitar and vocalist and have never on any occasion had my 2 x 15 MarkBass rig anywhere near flat out, we have our own PA and my bass rig is never put through it, just used as backline.
We had our first gig last weekend since the start of Covid, I have just took a photo of my amp settings as they were at the gig, the master is hardly on and my sound was plenty loud enough on the gig.
