My first amp had an oval 6" speaker. It was a total POS but it was my first amp!I mean why do we even have a 1x8 model
I completely understand the OPs request and can definitely go along with that. My guitar tone education was very slow. There was no internet when I started and no way to try a million amps. In France, there were few guitar shops and fewer that allowed you to touch the gear and even less willing to talk to you about gear. So I was an ignoramus for a long, long time. And I suspect there are many among us who just want to plug in a sound great and have NO IDEA what sounds good. I didn't. I had no sense of what was RIGHT and I was not educated enough to be able to make an informed decision. That took years.
But even now, many many years later and having had much more experience and discernment as to what sounds good or bad (to me!), there is so much to learn. And with 250 amp models, many of which we have never seen personally, much less played, a little help in the form of a suggested cab block would go a long way.
Some here snicker at it as unnecessary. It possibly is. We could survive without it. That does not make it any less a valid Wish List item which would make a lot of people happy.
