First of all I am not clear what some of you probably much better understand. The differences between what one gains by carefully ( not ruining the basses authenticity ) adding active electronics / higher boost pu, and frankly, the labels bassists give to these changes! "Punchiness" "sustain" "Boost" ( among other qualities of bass sound - you are welcome to add more) are some broad labels - and the electronics to gain these attributes. I guess this thread is not just asking for the how-to part, but the labels and accepted concepts for when we are modifying our sound from the original. Snce it is a broad topic it could "get crazy".. but it is also a topic that interests many of us. So starting with those 3 terms.."Punchiness" "sustain" "Boost", help me ( us ) associate a piece of electronic equipment with a basses tonal possibilities aka punchiness, boost, sustain ( can a bass increase both sustain and punch in one alteration? I tend to think sustain and punch are opposite ends of the bass sounds spectrum) I have never owned an active bass. I have no conception of the relationship between punch and boost! None! Honestly I do not understand the difference between gain at the amp and gain at the PU and gain in the active electronic end! Technology keeps advancing, so I am hoping some of you can help. I am a respected musician in the worlds I have inhabited.. but I know little about this area of expertise... yes it is possible! Thanks in advance.
