basey Posted May 25, 2005 Report Share Posted May 25, 2005 I am usually a lurker around here, but I've got a quick question for any of the tube guru's on here. I bought a Mesa Bass 400+ used from a gear trade in shop in town. It sounds good but the low end sounded a little flabby. So I replaced all of the tubes with new higher quality ones. (from lord valve). The tone sounds wonderful now. My problem is that now, when I first start the amp up and take it off standby ( after about 5 min) I get really loud pops for about the first 20 minutes. when it pops the volume reduces and then comes back after a minute or so. Any ideas? Quote Link to comment Share on other sites More sharing options...
