What is your opinion of this product?
This unit makes a decent bass sound much better, and makes a higher end bass glow. It adds musical tone control without noise, and can add a tube-like quality to the sound that adds tons of richness. The tone controls are centered where they add to (rather than ruin) the sound. At its most basic use, it is a very respectable direct box. You won't be able to touch what it can do without spending A LOT more money. Behringer really got this one right. It belongs on every bassist's pedalboard, and is the effect to own if you only have one pedal. I also have the acoustic version of this pedal, which serves my upright basses equally well.
