The HBE Bajo Mos is a bass specific mosfet clean booster capable of 15 dB of boost. I promised a comparison between this and the Wren and Cuff Phat Phuk B, as it's the only other bass specific booster I know of (other than the Markbass, but I HATE HATE HATE HATE HATE Markbass).
Well the Bajo Mos doesn't have as much gain on tap as the Phat Phuk B, so it won't push an amp as far into overdrive as the Phat Phuk, which is what I expected. It also doesn't have any dirt or really any coloration of it's own, also unlike the Phat Phuk. The Phat Phuk is a little more versatile because of those features, especially if you're not running it into a tube amp because it can still give you that little touch of overdrive and growl that a lot of players love. However the Bajo Mos is a great sounding booster, and perfect for those players that love their tone as it is, but just want a little bit more out of their tube amp.
Right now I'm running my bass with D'addario Chromes (flatwound strings). Here are some clips, first off, then on:

Then I tried messing with my wah with the Bajo Mos on:

To hear the Phat Phuk B for comparison, check out my clips on the Wren and Cuff website:

Those clips are done with roundwound strings, but you should get the idea.
So check 'em out, compare 'em, and let me know what you think!
