Mailist to discuss all issues regarding the Digitech GSP-2101 Guitar FX Processor

Hey M&M:

Your reply reminded me of the time, back in college, that I was asked to build a light show for a mobile disco.  I used an old washing machine timer to sequence the lights.  It worked like a charm.  Everyone looked forward to second rinse.

Had to install the pot because the LCD (salvaged from a dead laser printer) had a problem with the backlight getting too bright/hot and making the LCD go black. So far its been working for a couple of years.

It's located between the display and the hole for the power switch. I assume this pot alters the display brightness or contrast. I noted the original orientation of the pot and then used a small jeweller's flat-head screwdriver to spin it a few times back and forth.
