I'm expecting a new 6-string bass to arrive in a few days, and I have an important question. I currently run a jazz bass through the front input of the sansamp rpm (I adjust the volume to where the signal coming out is the same strength as the signal going in), out the 1/4 jack on the back , and into the passive port on my hartke amp. When I play my new active bass, should I run the sansamp into the active or passive input on the amp? Should I run the active bass into the LINE or INST LEVEL input on the back? Thanks for any help!
