Fender Volume-Tone Pedal
Input Impedance: 150kOhm (250kOhm Volume Pot)
Output impedance: 0 to 62kOhm, (Varies with Pedal Position)
Volume Control—Tilt the Pedal Back and Forth.
Tone Control—Rotare the Pedal Left and Right.
Note: This pedal uses a passive Tone control circuit and works best when connected directly to a passive guitar. If you must use an active guitar or put other pedal before this one, the output impedance of the active device should be 10kOhm minimum for the best performance.
