Well.. I realize the SL refers to Superlead. But, the Badger I said a circuit which is based on a plexi (Sonically; a British/Marshall-leaning tone). I’m certainly not any kind of authority on the various early Marshall’s or vintage Plexi’s. And I use the term “plexi” like I would Tweed/Silverface/Top Boost Ac etc.. *Im not being defensive or anything, but I’m wondering if not plexi then what would you call the Badger?? An amplifier I absolutely frickin love by the way!!
