Behringer Kobol Expander

This Synth is alright, looks good, sounds good and has the analogue sound you seek for. The knobs are plastic and don't feel so great, but you cannot expect more for this kind of money so I is is not a complaint, just an observation.
On the downside, it has some electronic pops sometimes and when you are recording it can bother, but it is not a big deal (I have not tried higher quality expanders, but I imagine it might be related to the quality of the components used and the construction).
Also, when you turn up and down the potentiomenters, the changes in sound are not so even, but again I don't know enough as to say if this is normal on any analog synth, maybe it is, it just makes you work more to achieve the sounds you like.
Overall a nice tool for such a low price, you can have a go it is not something you will repent buying, for sure, it is enjoyable and totally usable in terms of sound, but I'm guessing not as precise as higher level ones, like most of things in this world!
