Being an electronics student (and a generally curious individual) and working with a lot of ICs lately........... I go to thinking, has anyone ever taken a look at the components in a modern amp and though "I can find much better components than these. Let's swap 'em out." For reference, I was wondering specifically about a Mesa Walkabout. I don't have any problem with mine. I'm just a tinkerer and was wondering if it would make the amp sound "better" to put different MOSFETs in it (or swap out any other component for that matter). Full disclosure. I had this though just now and have not so much as popped mine open or even looked at the schematic. This is just a general curiosity being that we tend to have no problems putting "better" caps, tubes, resistors, pots, etc in older tube amps.
