Rockboard Quick Mount Type A

Clever solution to avoid the use of velcro.
Unfortunately the RockBoard provided alternative screws are wrong for MXR and/or EHX pedals: the assembly of the QuickMount Type A with a MRX and/or EHX pedal with the RockBoard alternative screws will permanently oversize the pedal mounting holes, compromising the geometry of the pedal case without any possible corrective action.
This information, at least, shall be stated as a "warning" in the product instructions in order to avoid possible damages on any part.
Replacement screws with a correct diameter will be a good, and expected, product improvement.

Claims to be made for MXR (as well as EH) pedals specifically, but the screws that come with the quick mount (I think they are M4 screws) are not compatible with the MXR sizes, which are #6/32, what with MXR being US-based. To be clear, I have an MXR pedal from about 12 years ago, they have not changed screws in the meantime. And for what the QuickMount costs, it does not look like it would be that much to ask to also include four #6/32 screws adapted to the MXR pedals.

To top it off, the manual suggests to just glue the pedal to the quickmount in case the "screws don't work". At that point, unfortunately, I might as well be using velcro.

Other than that, the build is good, and the lock mechanism works as expected, hence the 4 starts on quality. But since it just doesn't work for its intended use case, I unfortunately have to give 1 start overall.
