I'm planning on putting a bart preamp in my project bass and would like to keep the knobs to a minimum. I like having the stacked knobs so I can have plenty of stuff to fidget with while only having a few holes through the face of the bass. I'm wondering how important the mid adjustment is for getting just the right sound, and if the bass and treble frequencies are the same between the 2 or 3 band amps, or if they spread the highs and lows farther apart when using a mid control. Trying to decide between these two: - Volume/Volume Stack - Mid (push-pull freq selector) - Treble/Bass stack or - Volume (w/Active-Passive Push-Pull) - Blend - Treble/Bass stack. I like the blend and the active/passive switch, but I'm not too sure about dropping the mid control. Which would you choose?
