I have a Modulus Quantum 5 with Bartolini pickups and an Aguilar OBP-3 running at 18v. I like the tonal characteristics of this setup, but my overall output is just too low compared to my other basses (Sadowsky NYC Will Lee, Pedulla Pentabuzz with jazz bass profile Bartolini pickups and Bart NTMB). My frame of reference is subjective, but the Sadowsky seems kind of hot, and the Pedulla is at what I consider a standard output level, but the Modulus is so much quieter at the same levels on my amps. Are there any realistic options for boosting the output from the OBP-3 short of replacing it with an NTMB pre or something else? I wish the OBP-3 had a gain/trim pot I could tweak. In doing some searching, I saw one thread here where someone with a similar situation said switching to a 500k volume pot cured their issue. But that seemed odd to me... don't two pots of differing resistance allow the same amount of signal through when wide open? Am I misunderstanding how that works? Thanks in advance for any insight, there seems to be a great deal of good collective wisdom here.
