Kenny:
The Session 500 wasn't designed to be used as a bass amp. However, if you really want to use it for that, put a 1505-4 Black Widow speaker in it, and you'll get better low end.
Keep in mind though that this is an "open back" cabinet, and if you play it at loud volumes, you'll likely drive the voice coil out of it's gap. If you have a closed back bass cabinet, you could use the Session 500 amp to drive it, which would be a better way to go in this case. The best thing to do of course, is to get yourself a bass amp.[This message was edited by Danny Hullihen on 19 October 2000 at 05:46 PM.]
