Frequently Asked Questions - TBWP True Bypass Wah Pad G-LAB

How do I power the TBWP True Bypass Wah Pad?

You can power it using a 9V battery (not included) or a standard 9V DC adapter with center negative polarity. The current draw is very low, around 5 mA.

What does true bypass mean?

True bypass means the pedal is completely disengaged from the signal path when turned off, preserving your guitar's tone without any coloration or signal loss.

How do I replace the battery?

Unscrew the bottom plate of the pedal, remove the old battery, and connect a new 9V battery (alkaline recommended). Ensure correct polarity and replace the plate.

Why is the LED not lighting up?

Check if the pedal is powered (battery or adapter). If using a battery, it may be drained. Also ensure the power adapter is plugged in and working.

Can I use this pedal with a multi-effects unit?

Yes, the TBWP has standard 1/4" jacks and can be placed in the effects loop of a multi-effects unit or in line with other pedals.

Does the pedal have any other controls?

No, it is a straightforward wah pedal with only the foot rocker for the wah effect and a footswitch for on/off. No additional knobs or switches.

How do I clean the pedal?

Use a soft, dry cloth to wipe the exterior. Avoid using liquids or abrasive cleaners that could damage the finish or electronics.

The wah effect sounds weak. What can I do?

Ensure the battery is fresh or the power supply is adequate. Check that the input and output cables are properly connected. The effect may vary depending on your guitar's pickups.

Can I use a 9V battery while also connected to a power adapter?

It is not recommended. Disconnect the battery when using a power adapter to avoid potential damage. Most pedals automatically disconnect the battery when a plug is inserted.

What should I do if the pedal stops working?

First, check cables, power, and battery. If the issue persists, contact G-LAB support or an authorized repair center. Do not attempt to open the pedal yourself.

Connecting the TBWP with a guitar and an amp

1 - return signal connector 6 - guitar input (IN) connector

2 - area of placing wah-wah effect 7 - Indicator of wah-wah effect

3 - output (OUT) signal connector activation (ACTIV)

4 - 9V DC power supply connector 8 - send signal connector

5 - signal indicating foot placement (SEN) connector

9 - wah-wah effect 9V DC power supply connector

Connecting the TBWP

1. • Place inside the TBWP cabinet a battery and connect it (see the point "Battery exchange").
2. • Place the wah-wah effect on the wah-pad and connect signal and power supply connectors (please check if the power connector polarisation is proper).

1. • Connect the guitar to the TBWP input IN (plugging in the mono Jack connector will cause in switching on the power supply of the TBWP and the wah-wah) and the cable from the amp to the TBWP output OUT (see the diagram from the page No. 1).
2. • Place your foot on the wah-wah effect (the ACTIV indicator start to lit meaning the wah-wah effect is activated), then the wah-wah effect switch set to active position and block it at this position by the blocking ring being a part supplied with the TBWP (this ring eliminates incidental switching off the wah-wah effect while playing).

Pure mechanical diagram showing a bolted joint with no text or symbols

Switching on (activating) the wah-wah effect takes place in the moment of placing your foot on the wah-wah effect and switching off – in the moment of removing your foot from the wah-wah effect. The wah-wah pedal can be left at any position.

Switching off the wah-wah effect is performed by True Bypassing the wah-wah effect what eliminates influence of the electronic wah-wah circuit onto the guitar tone.

Switching on and off the power supply

Switching on the power supply is done by plugging in the guitar cable connector into the IN TBWP input and switching off the power supply is done by unplugging this connector.

It should be used mono Jack connector to plug into IN input.

Power supply

To supply the TBWP should be used internal 9V battery or regulated 9V DC external power supply adapter. Make sure that the connector of the external power supply adapter has got the proper polarisation.

REMARK: Damage of the TBWP caused by improper power supply causes the loss of the warranty.

Battery exchange

To exchange the battery you should make less tight two holding screws and to remove (taking off) the cover (see the picture). It is recommended to use high capacity alkaline batteries.

Fixing of the TBWP and the wah-wah effect

Fixing the TBWP with the pedalboard can be done by screwing it (see the picture) or by stacking with the industrial velcro (3.5 mm or higher).

To eliminate movement of the wah-wah effect over the pad, you should stick movement limiters (adhesive elements supplied inside the package) on the upper surface of the pad's plate (close to the wah-wah effect legs – as shown on the picture).

To fix the wah-wah effect we suggest to unscrew the legs and use the industrial velcro.
