The BOSS PW-10 V-Wah is the world’s first programmable modeling wah pedal. It has seven different wah sounds, all of which model the most famous wah sounds in history with dead-on accuracy. What many players don’t know, however, is that it is also a great sounding distortion pedal, with seven different COSM overdrives and distortions available, and it can combine any of the seven ODs with any of its seven wahs and store the sounds in any of three program locations. It even has a Noise Suppressor to keep the distortions under control. Here’s a list of the seven distortions:

• METAL ZONE: Models the sound of the BOSS “MT-2” METAL ZONE
• ADVANCED MUFF FUZZ: Models the sound of the Electro-Harmonix Big Muff Pi
• VINTAGE OD: Models the sound of the BOSS OD-1 OverDrive
• DISTORTION: Models the sound of the BOSS DS-1 Distortion
• TURBO OD: Models the sound of the BOSS OD-2 OverDrive
• BLUES OD: Models the sound of the BOSS BD-2 Blues Driver
• BOOSTER: Booster with flat response

What is the procedure for changing distortion sounds? There are just eight simple steps:

1. Switch off the PW-10’s power.

• When running on battery power: Disconnect the connection plug from the INPUT jack.
• When running on power from an AC adaptor: Disconnect the plug from the AC Adaptor jack.

2. Turn the TYPE knob to ADVANCED.

3. While holding down the MANUAL/ MEMORY button, switch on the PW-10’s power.

• When running on battery power: Insert the connection plug into the INPUT jack.
• When running on power from an AC adaptor: Insert the AC adaptor plug into the AC Adaptor jack. The ON/OFF indicator blinks six times, and the PW-10 switches to DRIVE SELECT mode.

4. Turn the TYPE knob to select the DRIVE type.

Here is a chart that shows which TYPE knob setting to use to select the various Drive types:

5. With the WAH RANGE knob, set the Noise Suppressor threshold level. You can eliminate louder noises the more the knob is turned to the right. The Noise Suppressor is turned off when the knob is turned completely to the left.

6. When you have set the threshold, press the MANUAL/MEMORY button. The MEMORY indicator blinks.

7. When you want to change the output level for DRIVE, use the DRIVE knob to adjust the volume level.

* You cannot adjust this output level if DRIVE is off when Step 8 is carried out.

8. When you have finished making the settings, press the MANUAL/MEMORY button. After the MEMORY indicator blinks and the settings are saved, the PW-10 returns to normal operation (“MANUAL” mode).

* You cannot switch between MEMORY and MANUAL while in DRIVE Mode.

By the way, these and several other procedures are actually printed on the bottom of the V-Wah, in case you forget how to do this, and want to get the most from your V-Wah.
