The FBT MM 121/B is a portable PA/keyboard amp, not a dedicated bass amp—it lacks the SVT's mid-grind and tube compression. Pushing mid to 6 compensates for the PA amp's flat/scooped voicing. Gain at 6 adds some presence without distortion since the amp won't naturally break up like an SVT. Your Jackson JS2's passive PJ pickups are lower output than Rex's active EMGs, so bass stays high at 7 for body. Keep treble conservative at 5 to avoid harshness through the PA-style speaker.
