I guess you get whatyou pay for and this is somewhat true for this pedal as it can definitely introduce some noise to the signal should you require more volume. Leaving the volume below 40% (not using the boost feature) is perfect and it really doesn't raise the noise floor that much, you will be satisfied. The Attack feature is indeed a nice touch and is very usable, I really like the slower attach option for slapping and fast attack for mellower tones. The sustain is not extreme, just perfect for bass. I am not a fan of the housing or the design itself but it is sturdy enough for gigs and whatnot. I am overall very happy with this pedal, though I would probably use a higher-end model for studio recordings is that is your thing. I would not ask for more in this price range. As for the tone, I really like how it makes my bass a tad bit warmer so I always have it on, and it sounds perfect after drive/fuzz effects too!!
