I love Sansamp Bass Drivers and am thinking of getting one. The only thing is I'm also considering getting an Ampeg or Mesa (a tube one) later on and wonder if the Sansamp will be any good with those amps? If I hold off buying the Sansamp now I would be able to get a new amp sooner but my setup now would really benefit from a Sansamp. I just need to know if it will continue to be useful once a get another amp. Opinions?
