I'm with you, having access to an amp and some pedals makes that amp a great pedal platform
I think though it's supposed to mean a relatively clean and uncolored sounding amplifier that you can use to run "amp in a box' type pedals into.
So slamming a semi cranked up blackface amp with a tube screamer, though a very classic use of amplifiers and pedals, is not an example of the "great pedal platform" idea.
I'm positing that the ultimate extension of this approach is one of those powered speakers that you feed your Helix or whatever those gadgets are called into.
I don't know that I have a "great pedal platform amp" I have a 5FI clone, a blackface champ, 5e3 clone, a silverface deluxe reverb, a matchless lightning clone and a DR Z. remedy with no Master Volume.
But I think that your choice of speaker might also contribute to a great pedal platform too. Uncolored vs colored, I'm going to in this case posit that an EV12 is more of a great pedal platform speaker than a V30.
