Being unhappy with the output & tone of my passive '51 PJ Benavente, I decided to gamble and get one of these. It got here last week, but alas, no band practice during the Holidays, so I haven't run it through my rig. I did spend some time at home through my Pocket Rockit, and the initial results are positive. I can get the output level of my passives to be close enough to my actives to use them during gigs. The onboard EQ (Channel 2 meant for passives) is very powerful, and the Channel 1 preset EQs include an enhanced bass/mid/treble contour or a scouped bass/mid sound which would be great for some of the one trick pony basses I've had. The Bassbone itself is built like a tank, it's the heaviest pedal I've ever held, and it looks to be built for the long run. Has anyone used one of these through their rig? If so, I'd like to hear your comments. I'll update this thread once I have.
