An input and an output jack (normal), a switch active / passive on the side, a three-position switch on top and two knobs (volume and overdrive). Note the posibility to power the pedal with a stereo cable when using an amp EBS.
, Unscrew four screws to access the battery, it is far from the pedals boss. But as the batteries are quickly devour it there is more attention and is connected to the mains.

The pedal looks solid and indeed it is. It took quite a fall, and above all many kicks on the switch and nothing wrong, the metallic casing and components (pots, swotchs, etc..) Are in perfect condition. Quality!
2 knobs, a three-position switch, it can hardly be simpler. You can find plenty of different sounds with little galleys.
The manual is clear concise accurate (for what it is used ..) and provides examples of setting type.
Used on an Ibanez GSR190 (entry level), we get very good results already. The standard and overdrive tubsim possible to obtain a slightly spicy (when we go in the treble) or totally saturated (style hysteria Muse, live version). The effects are well suited to low, thanks to the low frequency bypass.
The overdrive flat (overdrve linear at all frequencies) is more difficult to control. Use in moderation for not sound trashy to drool all over.

Used on a Cort Artisan is a joy. The character of the bass is well respected and the effects are very clean, including the overdrive flat. The pedal is expensive, but the quality is there!
Note that the pedal can be used entirely in the studio, since the bypass is real when we cut the pedal.
I use this pedal for two months and I admit that I use almost constantly, even if only to spice up the sound (the pedal can also compress the sound when you put the saturation to a minimum , to go from fingers to slap without exploding the ears of everyone). A successful overdrive for bass is often a bet is quite risky but, nickel, well above what I could test other (the pedals to less than 100 € I will not name names ...). It is true that the pedal is quite expensive (€ 158 with the external power supply), but frankly it's worth, I can not do without! In addition, it can be full of cum, the switch is solid underfoot, the metal casing and the knobs are very sturdy. With experience, this choice I would do without hesitation.
Just a little tip: buy (or be offered an alim because she eats the batteries in no time. And to change them, unscrew 4 screws, in other words not super convenient ...
