Morley M2 Passive Volume Pedal as Expression Pedal with HX Stomp
Thanks to several who posted previously about getting non Line 6 pedals working as Expression pedals. It does work. There are several earlier descriptions about getting pedals like the Morley M2 working, but there is one additional piece of information that will be ESSENTIAL for some Morley owners: Although the circuit board is labeled as 10K ohms, some of the Morleys were actually built with 1M ohm slide resistors. (Inspect the pot itself, it will be labeled in some way, a value or part number, or slap an ohm meter on it.) They're not going to work no matter how you jumper them. In my case I was able to find a 10k with the same physical dimensions (common - the good folks at Morley sent me one). Replace the 1M ohm with the 10K Ohm unit and the pedal will work perfectly with a STEREO (TRS) cable. I have several shorter mono (TS) cables, so I removed the connection to pot leg 3 and jumpered it to pot leg 1 and the pedal works great with a mono cable. * you are connecting the pedal OUTPUT to the EXP input
