I will go with Peter's assessment of anything amp-related any time.
Everyone has their own opinion on how to do what they do.
I have seen some of the other high-end p-t-p wired amps and they do not incorporate nearly the things Peter's amps do, and they sound very similar to each other in many ways.
The fanboys of these amps are quite prolific in the states, but then these are some of the same people that are stuck in the 1950's in their thinking about how everything amp-wise/and guitar-wise should be done. Why are these folks not still buying land phones and using ancient types opf computers, based on this reasoning?
If you only use your eyes and what is "perceived" as being the "only" way to do things, you wind up missing out on a lot of great inventions that may push the envelope on musical gear.
I'm one of, if not the oldest player here that still plays out constantly, and I have more forward thinking then a lot of the opinionated peeps on some other forums that look down their noses at anyone who doesn't follow their line of thinking.
Besides, how many of you willl own the same amps for so long that you will need internal work done that often? In my experinece, and from what I have read, not that many people keep an amp that long. They wind up buying older amps, which may need work, but there are intelligent people out there doing repairs on PCB amps by simply replacing the burned out part.
Mesa amps that used to be p-t-p wired as with Marshalls, Vox's and Fenders, et.al., do not all sound the same from one of the same exact model to the next. I know as I went through these amps when they first came out. If a PCB is done correctly with high quality parts soldered to it, it will hold up to the rigors of hard use and be more consistant from one amp to the next of the same model. In all of my time playing, I have never had a problem getting a PCB fixed if needed, and that has been practically never. I have had no more problems with either type of wiring, and probably far less then some people have had the misfortune of having.
You cannot tell another person that their way of thinking is wrong, as it is only their opinion and yes, they are entitled to it. I however, don't plan to miss out on anything such as Peter develops while I am still breathing. You may not know it yet, but life is too short to deny yourself the benefit of modern thinking in musical gear. I have been playing the old gear since it was new. I cannot allow myself to keep getting the same things with just a twist on what has been out there for 50 years. Look at all the great new inventions and innovations developed by people such as Peter have done. I might be old and in the way, but I try to stay way ahead of the curve in my thinking on gear. I have never been let down yet, and my tone has only continued to improve. I see no down side here.
