What a fascinating thread! Cheers for pointing that one out
So if you put the treble control in its midpoint, it will be pretty much flat - but the bass control in a similar position will still be giving a reasonable amount of boost! Assuming linear travel on the pots of course.... How odd!

That thread explained it all far better than I ever could.
The Tonepump is pretty quirky to say the least, but it just sounds so good IMO.
The other active basses I've owned have always had a slightly compressed, processed quality to the sound that I've never really been 100% happy with - to me the tone pump doesn't suffer from that, it just seems really responsive & "open" sounding.
