Analog distortion bass pedal with five controls:
- LEVEL control (adjusts the effect's level). Use it to compensate
any volume differences between the original and processed signals.
- HIGH EQ control (amplifies/attenuates high frequencies)
- LOW EQ control (amplifies/attenuates low frequencies)
- BALANCE control (adjusts the mix between direct and distortion sound)
- GAIN control (adjusts the gain of the direct or distortion sound.
Provides a wide sound range from crunch to fuzz and distortion or a simple boost.
Very rugged yellow aluminum housing.
Battery or PSU operation (battery included).


UTILIZATION

Very simple overall configuration, effective controls and very intuitive use. The user's manual provides nice setting examples you can fine tune to match the sound of your amp and your bass.
Like with every Boss pedal, the learning curve is not very steep but you'll have to take enough time to find the tone you really want because the controls are precise! Precise equipment requires precise use!
The distortion sound is a variation of the clean sound, so you'd better find your own clean tone before setting the distortion sound.


SOUND QUALITY

Wonderful sound! It shakes the walls, but always with class.
It gives you everything you want from dirty fuzz to light crunch and heavy distortion.
I use it with a Cort B4 and a Trace Elliot stack (GP7SM-250 head) and it was a delight from the very beginning! Even with all controls in center position, the sound is good!


OVERALL OPINION

I've been using it for some days and I'm very happy. Great product for rehearsals and live gigs. Boss products have a very long life
Before buying it, I played with an Electro-Harmonix Big Muff. It' not comparable. The Big Muff had less lows, the sound was not deep enough and it was too dirty! I don't regret my choice.
The price is ok considering it's a Boss stomp box: good manufacturing quality and sturdiness. I wouldn't hesitate to buy it again!
