Triple footswitch , no name , no ratings on switches, GFX 65, 1999.
Impossible to use as a mind of its own which channel it wanted to be in.
On resistance anywhere between 200 ohm and 100K on each of them.
At least easy enough to get inside them, dissolve away the grease and deburr
the rough edges and put back together again
