Hey sambonee
For me it is kind of a combination of nostalgia and enjoyment. The Bandit is just an all around good sounding amp. Plug straight in , use pedals, doesn't matter. Within seconds you can get good tones. It doesn't do Marshall tone as well as a real Marshall, or Fender as well as a real tube Fender, but it just sounds good.
When I was a teenager, it was a big deal to get my parents to drive me the 45 minutes to Bud Monahans House of Guitars in Peterborough, where I would wander around checking out the Peaveys (they were Peavey dealers). Until my mid 30s Peavey is what I played. Since I have been on the endless journey of Marshall, Fender, Badcat, Mesa, etc. But the Bandit just feels comfortable.
