Studiologic MP-117 Midi Bass Pedal

I've been using this with my Korg MXD sound module for about 4 years and it has been faultless. It gets kicked and jumped on but continues regardless. The pedals just touch the ground when pressed - which is perfect so you can't ever put too much pressure on. If there is a fault, it is that 2 hands are needed to make a change to the bank or octave whereas an up-down rocker would be better so you could do it with your feet. It means you have to plan your performance but it is a tiny issue.

The final user is a professional organ bass player and has realized that on this bass pedalboard made in plastic which he has ordered all the keys are functioning well, except the key G which he feels doesn’t stand firmly when he puts his foot on it and not as solid as the other keys and he has observed a specie of missing small color like a small white missing dot on it.
He has been asking me whether there is any way he can adjust that key which he feels is not enough solid, because when he has analyzed it, he has seen that it has a spring inside and he fears this particular G key might brake after sometimes, but he says it is a general sensation based on his so many years experience playing on bass pedalboards.He has been in fact playing on so many bass organ pedalboards for so many years, and I believe he can feel the difference in between the brands.Then, my general opinion is not bad for its price, but I feel that it is more conceptualized to be as a MIDI pedalboard rather than a pure organ bass pedalboard which is generally used under harsher conditions than a pure vintage organ bass pedal board which in general looks more solid.
If not all the other features are functioning well for now.
