**FULL DISCLOSURE/UPDATE**
In this thread, I posted a video review of the MGL 50 HG because someone requested it. I sold that amp back to Mark from MGL soon after making the video. After Mark got the amp back, he examined it and sent me the following message:
The previous owner, from whom I bought the amp, did not disclose this information to me. So unfortunately, this review is not truly representative of the sound as Mark from MGL intended it and I want to fully disclose that information. I apologized to Mark and hope I can own an MGL 50 again in the future and do a review with the amp biased properly.
