Metasonix‘ Eric Barbour demonstrates why the company’s products are “costly” – they are hand-made in the USA, and the owner of the company does the final assembly and testing on every item, with his own hands.
In the 9-part video, Barbour assembles and tests a Metasonix S-1000 Wretch Machine vacuum tube synthesizer.
Note: Barbour warns that this video is “very boring”!
I liked this! It's interesting to see what goes into one of these things. Part 8 has no sound unfortunately but it's not one of the most interesting parts I'd guess.
