Feature:
What made this box unique compared to other pedal DI/pre-amps, this comes with Tube emulation mix (Blend knob) which gives a much warmer tone, harmonics/resonance sensivity level (Presence Knob) which is good for slapping/popping, and finally, the Drive knob which give you options to make your bass growl deeeep.

Quality:
I have own this box for 2 years now and there was one point in time that a sound crew while moving the stage equipments unknowingly placed the bass cab (a 15-incher SWR, 100+ lbs) on top of this pedal. All the knobs still worked well to this day with no scratchy sound on turning it. For awhile, I thought I had lost this one with this incident but true enough - the quality is good.

Value:
This is a good buy given the usefulness of this gadget.

Desirability:
This gear is housed on metal frame with Navy blue color; labels are presented in yellow and complemented by a sensible control layout which gives it a professional and classy look. The color combinations that presents this product makes it easier to read the gear labels on dimly lit stage.

Sound:
This pedal comes only with a 2-band EQ. But I had observed that as I pan the knobs of bass and treble beyond 12 o' clock, it seem to adjust the mid-lo and mid-hi frequencies along with it. On a 5-string bass, a much fatter and aggressive bass tone is produced when playing on the low strings A, E and low-B; while, playing on strings D and G gives a much higher treble which is okay if you're doing slapping/popping. But if you need a fatter sound definition playing on the D and G strings, you need to adjust the EQ at your amp. All-in-all the EQ provided by this small box is sufficient in most bass playing. It would have been nice if this comes with 4-band EQ; but then, given the price and its size this is what we get for. Other than the EQ setback, this unit gives a deep bass sound presented in a much warmer tone and options to make it growl (overdrive) or have a fat slap tone.

Ease of Use:
Tonal adjustments are presented thru knobs which makes it easier to adjust compared to other "hi-tech" floor boxes which utilizes push +/- buttons.

Support:
I never had problems with this gadget; but given the quality of this product, support service probably is as excellent as the product they produce.

Overall:
Some people view this gadget as a DI as its name implies. I view this as a stomp box with characteristics of a pre-amp. I said this because - as I pan the drive knob, somehow it increases the output volume - which is not good when changing tonal settings on live performances. Thus, I am pairing this box with a compression gear by Digitech (Bass Squeeze). Overall, I like this gear. My 5-string bass is constructed with Mahogany body, walnut/wenge neck with rosewood fretboard which provides a natural fat warm tone. But if I wanted to do slapping/popping which usually requires a bass with a brighter sound, my bass comes short on this. So, instead of buying another bass, I bought this gear and used this mainly for achieving a fatter funky tone and for some rock implementations requiring overdrive.
