Other than a scratchy volume pot that developed after one year of ownership, and after the one year warranty expired, I didn't have any other problems. The scratchy volume pot was easy enough to fix. Just slide out the amp by pulling it out via its faceplate after removing the back screws. Applying deoxit to the volume pot shaft was all it took to fix the issue and it has been running fine ever since. There could be one or screws underneath that needs to be removed too, but I could mistaken for the MCTH whose scratchy volume pot I fixed the same way.

Mine came from the third drop, which was before Massdrop's rebranding to Drop, and has been sitting boxed up in my garage for the past year.
