Well the Bassman was originally a bass amp, but now it's primarily used by guitarists. But the old Fender amps in general were all blow-able, whether for guitar or bass. They had more power than their speakers could take.
I think your biggest worry might be if you play it super loud and you're feeding the speaker lots of frequencies it's can't reproduce, it's going to build up some heat (the speaker). But I've played bass through guitar amps before and never had a problem. Just don't turn it up to 10 and I'm sure it will be fine.
Could you please explain what you mean by "blow-able" ? Are you talking about speakers or the amp?
The statement about "feeding it frequencies it can't reproduce" I question as well. Since we're speaking about Guitars and Basses here and not synths or a Grand Piano or Pipe Organ, please tell me where those extra frequencies are coming from.
User misuse can account for a percentage of speaker failure, but usually that abuse is just as likely to be from UNDER powering a transducer, using it in an improper cabinet or some similar out of parameter application, as it is to be over powered.
I still maintain that the proper cabinet is more important than the amplifier being used in this case. A double 15 or 4 x 10 cabinet, with a closed back and a tuned port (Bass reflex) or even a 4 x 12 Marshall type (infinite baffle) is more appropriate for Bass Guitar applications than a speaker cabinet with an open back (Fender Twin type), all other things being equal.
You may feel differently.
