hi,
with the echolette, there seems to be a problem:
right now TONE #1 is connected to GATE, which is a mistake
...........EDIT:
simplest correction: TONE #1 should come up by 1 row, from KF to KE
......................I checked the
original schematic and in that, the tone is not connected to the tube/j-fet, but to the two ends of a 100k resistor...
I'm building this right now, so I'll get back shortly...
