A customer brought in a DM-300 with broken switches. This is a really interesting piece of equipment that I've never seen before, so I thought it was worthy of writing about.
This is an all-analog delay/chorus unit that runs off 120VAC. Similar sound to the DM-2 but has more control over input and output gain. This thing distorts so well I was blown away.
The two level switches were broken after sustaining some physical damage. Tracking these down was difficult but I managed to track down some DM-200 switches. These switches were a little different, but fit very well.
