I got one of these yesterday. This thing is just so incredible in what it does to your sound. When we demoed it in the store, we did it using the Yamaha Patitucci Model 6 string. First we ran the bass as is through a Hartke 8x10, Hartke 1x15 and, Hartke 7000 head. Then we threw in the DB 924 into the mix, and the sound just completely filled up. I don't think i could even describe to you how much more we got from the bass.
