Verified to be in working order. Purchased from the reliable musical instrument store, Hoochies. For reference: A Thomas Organ-made VOX V846 Wah. Based on the serial number, it appears to be from 1976. It features a TDK inductor, silver capacitors, and other characteristics typical of wah pedals from this era. It has two 5117 transistors. All the parts on the circuit board are original. The original curling switch has not been replaced. This unit originally had an AB original pot, but it couldn't be cleared of scratchiness, so it has been replaced with a BLACK TOP pot. It has a good low-end response while still retaining the vintage wah feel. The original pot is also included. Type... Electric Guitar
