BB pre amp is great and allows you to balnce the tone well with other things as it is boost and cut. Currently enjoying what its doing with my p bass. I found, and you may not give a damn , is that while one pedal can maybe cover a low gain or moderate gain we would rather have two pedals that do each sound equally well cause we love to buy gear.
I've happily loaned guys on here a pedal to see if it was what they were after during quiet, non-giging times but I'm busy over August. If you're still thinking about a BB pre amp gimme a shout and I can bounce it your way for a few days near the end of the month.
