Multi-Effect Pedal for Electric Bass

Latest User Reviews
Excellent for practice
This is really all you need to start, in a nice package. Sure, not all effects sound great but for 100 euros you get some great ones, plus a metronome, tuner, looper and the ability to practice through headphones. Extremely portable. Couldn't recommend more
Super pleased with this device for practice and performance
It's great to put some headphones on, and practice at home, use the aux input to play backing music, or use a drum loop. I have also used it in performances.

Great
Would have preferred a metal chassis. This is a bit too plasticky and feels cheap and scary to stomp on. But boy, does it sound good. And lots of different sounds to choose from.
Great with aux input (would like a volume knob for that though) and headphones jack for playing at home while the kids sleep.
surpsingly good.
i bought this expecting it not to be that good but was pleasantly surprised. i originally bought this expecting myself to use the darkglass b7k distortion but couldn't find myself in that and figured that the sansamp model works really nicely, the fact that got a model of the avalon u5 di in there is also a very nice addition, it may not be as clean or sound as similar but it's still pretty damn good. (then again what does one expect from such an inexpensive pedal lol) I do wish that the software was a but better in terms of handling and that the food switches had more options in terms of assignment because i find myself switching to other modules as opposed to turning on/off the module I'm aiming for but that is, of course, a minor issue and if i paid better attention to it. all around a good pedal specially for the price.
10/10 would buy again.
Wow!!
Here you get a lot of good sounds, and drum tracs to practice to.
Awesome pedal for the price.
Nice build quality to.
Fun
I play just for fun, some punk music, and this pedal gives you a lot of funny effects options and you are able to customize them either.
Good sounds for practice but also for gigging.
Very much useable
First of all, for this price.... You can't ask for more.
That being said, yes ofcourse, you will most likely NEVER get sounds that you will get from Darkglass or something along that line. However, if you actually spend some time (A LOT of time) with it, you will get very competitive tones out of this pedal. EQ section is definitely pretty solid, but more specialized effects such as phaser or distortion is.. okay.. ish....
The construction is VERY uninspiring. The outer casing looks like low quality straight out Audi interior... ;) I have gigged this pedal 3 times so far, I haven't had any problems with parts falling or snapping off, and hopefully it stays that way.
You can set different channels up with different sounds, or you can set it up according to your setlist. Each channel houses up to 5 different effects, and it comes with a function where you can disengage each effect by stomping on the left pedal. Pretty cool. I'm a bassist, and I don't use a whole lot of different effects, so if I wanted to, I could set up a sound and effects I need for a typical setlist into one channel.
Overall, I recommend it. Do spend some time with it when you get it. It's worth the price (very low price).
Great Multi Effects
Awesome bit of kit.
Pedal building presets is great!
Excellent as practice tool with tge aux in too
