Supro amps had a booth at Guitar Summit 2018 in Mannheim, Germany.
I had very little experience with those amps before and decided to stop by and take a closer look.
The one you see in the video is called Supro Black Magick Reverb.
Big thanks to Musik-Produktiv for letting me use their space to shoot this.
