It happens.
I was a huge MK IV fan and still am but when I started playing out with friends weekly and a couple of town gigs it was apparent my home settings were pretty much garbage live. I felt like a dope for giving those settings out so much throughout the years without having tested them in the real world. When I got the MK IV to cut well I did not like the tone at all so it got to the point I did not want to use it. Honestly I was trying to make it sound like a Marshall and failed big time
What happens in the basement you can throw out the window live IMO, totally different enviroment. Your fx is different, noise levels different, power source, etc..............
Yeah there are some basement formites I listen to but they used to gig out at one point or are still involved with mixes. Guys like Erock I listen to as I can hear he dials in his stuff to cut. The low end bass that some like will not work live.
