I play a Silvertone SS-15B with EMG pickups (sorry, don't know what kind) and my amp is the old Fender Bassman 100 (the one with the 15" speaker). I play at church and I am plugged into our PA system. What are the best settings for my amp (all at 12 o'clock or something else)? Thanks in advance for your replies. This is my first posting.
