Sure they would work. Also, the reso head on the bass (having a port) does have a lot to do with the sound, but do they even make EC2 SST bass batter heads? I dunno.

I have EC2 SST heads right now, I don't see why any heads wouldn't work for that situation unless they were like J1's or something. EC2s are probably more suited to prog than most heads.
