## Questions & Answers

**Q: trying to decide which one to get... what exactly does the expression pedal do?**
A: The expression pedal offers several functions. Yes, it can adjust volume or be used as a wah but it can also adjust intensity of effects. It's nice to be able to adjust the amount of overdrive or phaser, etc.., for example, with your foot.  You can use it to adjust the pitch when using that effect.

**Q: Can i use it with an ukulele because i'm a bass and ukulele player. Also can we connect it to an audio digital interface like focusright Scarlett?**
A: Yes you can connect it to focusrite interface, I don’t know for sure if a ukulele will work with the bass processor since if mainly for the bass guitar.

**Q: Unit won't stay powered on for more than a second when under battery power, second one I ordered with same problem, purchased end of August 22.**
A: Use the android plug, it works great for hours, don't drop anything on it, falls,  or spills she's easy to bust

**Q: How do you get the device that you plug in to play music through Zoom(such as phone) to play in stereo? I can only get mine to play mono.**
A: You must be plugging your phone in with a mono cord, I would try a different aux cable.

*by F***Y on 19 October 2022*

I play bass for the all pro band Rat Soup so quality sound is a high priority. I typically don't use effects and have always wanted to try them so I purchased this unit. I was not disappointed. A pure signal chain is important to me so I wanted a clean bypass. The bypass signal is very close to the original. So it's not so big of a loss in a live performance, but I would not record with it. As far as tones, there are some great ones and they sound pretty close to the actual stomp boxes. So if you are on a budget and want to try out some different amp tones or effects this is a cool pedal. I love the syth, wah, auto way, and pitch bending effects. For the money this unit is well worth it. Some people complained the wah is not that great, but to me it sounds good. I have a Morley bass wah and this thing is close. As far as usability and gigging . . . I couldn't find a way to bypass a patch other than create a clean patch and jump to that from the patch I want to use. That's fine if you only use one patch, because you'll have to scroll to patches you want to use rather than turn it on or off. You can use the pedal in stomp box mode where you can turn off individual effects with the pedal but not the group. My work around was to use a bypass pedal with this unit. Then I can utilize my pure clean signal and jump to and turn on or off an patch for the whole or part of the song. The looper is cool, but it does not retain the recorded loop after you power down the unit. I wanted to use the loopper to play a sample while playing live, but that's not going to work unless you record the sample right before you play. The tuner is great. So for a practice tool with a tuner and a mini drum machine AND the ability to play with some effects, it's awesome! If you're looking for gigging with great sounds then stick to stomp boxes. But if you want to test out effects and play a few live with a bypass pedal then get this thing. After thinking about it, I changed this from 4 stars to 5 because of the price and what you get!
