Re: Amp question
You could probably run the Bassman into the cab, but then it wouldnt sound like the Bassman. I had a 2555SL 50 watt Slash Signature, which was just a Jubilee but not silver and it had Slash's name on it. It was a killer amp I wish I never sold, but like the story goes, I had 2 Marshalls and no money so one had to go. Although I think I let the wrong one go looking back on it.
Even if you didnt use the Bassman with the cab, it never hurts to have an extra 4X12 sitting around eventually you'll have a head for it again.
Basman is a hell of an amp though, but it's almost a sin to throw a distortion unit in front of it.
