    Really affordable bass multi effects pedal with a ton of options to customize. It also has a pretty decent looper and drum presets.

    Really useful for practicing with headphones, I like the fact it runs of battery and also has Aux in for playing along with my tunes. It has lots of options to create different tones, but you can just crack on with the first patch and get playing straight away.

    The effects and looper are fun, but I mainly got this as I wanted to use it as a headphone amp, instead of bothering with a diddy practice amp. The fact it has drum patterns and I can plug my phone in to play along to makes it perfect for me. For home use it's construction is fine, and I have it sat on a table. It's plastic, so not sure it would survive gigging, but as I won't use it for that don't take my word for it. Runs off batteries too, or mains (adapter not included)

    Perfect for practice at home. Easy to use and very simple to set up. I can practice with headphones on and have a backing track coming through at the same time. This thing is amazing for the price.

    Really flexible and vast range of effects, but to get the best out of it, you need to spend some quality time learning how it works, and loading up all the effects using GuitarLab. My only gripe is that many of the effects introduce some signal noise, so i have had to use 2 of the 5 effects slots for most patches with a graphic or parametric eq and noise gate to limit the impact of the noise. A real pity as it could have been a perfect alround multiFX unit. Maybe this is something they could fix with fiirmware updates (Zoom?)
