I got this unit for rehearsal and practise use for my smaller amp. I already purchased Hotone Ampero but I was little disappointed because that unit has not the multi-use EXP pedal -> no possible to use EXP with volume and wah at the same time. That was quite odd to me... But in that case Valeton GP-200 is quite good alternative! Very solid made and sturdy metal case and the metallic foot buttons are high quality. There are 6-8 possible knobs to program and with external EXP/additional pedal you can get even more. I have tested that function with Hotone Ampero Switch 2-button and also Thomann own FS-2 button extra pedal, they worked fine with Valeton!
Pros :
+ very versatile and quite cheap multieffect
+ lots of features, amps, cabs, effects etc, I´d say well enough...
+ packaging was good and very informative leaflet inside
+ quite good editor after all and within that you can quite easily update firmwares
+ I think the editor software works also with older FW´s in the unit so they wouldn´t have to match each time?
+ you can program up to 6-8 or even more foot buttons with Hotone Ampero Switch or FS-2 type extra foot controller
+ the upper set of buttons are set higher so you cannot put the lower on by mistake
+ you can use the integrated EXP both volume and wah/switch them on/off in the same bank/preset
Cons :
- people might not know this brand at all so they might miss this product
- I think you cannot use so many MOD/FX effects at the same time, for example chorus and flanger at same time is impossible?
- the editor software might be quite challenging/hard if you have not used these kind of multieffects pedals
- if the bought power unit/adapter fails, I don´t know how you can get a new one?
- I am not so sure how long they keep updating this units FW or editor software updates, the next model might be already coming...
