Preamps are nice. Eq also works nicely.
Bluetooth connection is bad I have to say. Sound quality is degraded a lot so it means you cannot use your bluetooth connected audio to work on or listen nicely.
For recording, it could work with practice recordings etc... not so defined or clear per se; however, it is enough to record nice sounding stuff with low noise.
So for the price it is a nice little desk which you can do a lot of stuff; but, they could leave the bluetooth out; it is that bad.
Also, effects unit is not bad sounding. Unless, you are trying no input mixing or some experimental stuff. Because, it resets itself every time you change the parameters of the effect. So, that was an another issue for me.
Overall, it could be a nice desk for practice. but I would say, not very handy for experimental musicians.
