The VHT Special 6 is a hardwired amp roughly based on a Fender blackface champ. I purchased this combo specifically to practice mods, which included:
-power tube bias switch for 5881 and EL34 (6L6GC not really recommended)
-adjustable bass and mid controls
-adjustable boost
-speaker swap and plywood baffle upgrade
also check out the video where I compare 5881 and EL34 power tubes: [ Ссылка ]
The demo portion uses a 6V6 tube. I used a partscaster start that is alder/rosewood with Fender Fat 50s pickups. This video was long enough, so I'm going to post another one or two showing various power tubes.
