It's an Audio taper pot. They react that way. Linear taper is what is in the NG and Combustion series and Im pretty sure my Z too.. If you'd like a smoother and more consistent roll off, swap it for Linear. (B500K)I received my SP1 two days ago and opened it last night. The bass is gorgeous, but I’m noticing something odd with the volume knob. Instead of a smooth, gradual 1–10 volume sweep like I’ve experienced with every other instrument I’ve owned, this volume knob behaves differently and think I may have a problem.
At full volume (10), I set my peak in Logic at −8 dB. At 0, it registers no sound, which is expected. However, during the first 60% of the knob’s rotation, the volume stays extremely low, hovering between −45 dB and −40 dB. From roughly 60–80% of the turn, it increases to around −35 dB to −30 dB. In the final 20% of the turn, the volume spikes sharply to between −12 dB and −8 dB.
This doesn’t seem normal for a volume pot. Let me know what you think.
In other words: at 0 it’s silent, which is normal. From 1–6, the volume remains very low and barely changes as the knob is turned. From 6–8, it gets slightly louder, and then from 8–10 the volume jumps dramatically.
I swapped my vol pot for a 250k Audio pot to cut some of the highs (i felt SP1 was too bright), but after 2 gigs like that I'm going to order a linear taper instead. It wasn't crucial with this particular band on this run, but I can already tell it would be more useful to me.
