Tom Morello
Power 50™ Overdrive

For more than 30 years, the key component of Tom Morello’s raw, hard-hitting sonic voice has been his amp setup. The MXR Power 50 Overdrive captures the sound and functionality of that setup for use with any rig, whether you have a simple combo amp or a high-end custom stack.

Basic Operation

1. Run a cable from your guitar to the TBM1’s INPUT jack and run another cable from the TBM1’s OUTPUT jack to your amplifier. If using the effects loop, run a cable from the TBM1’s SEND jack to the input of the first pedal in your loop. Run another cable from the output of the last pedal in your loop to the TBM1’s RETURN jack. Note: effects loop signal is only active while TBM1 is engaged.

2. Start with all controls at 12 o’clock.

3. Turn the effect on by depressing the EFFECT footswitch.

4. Rotate VOLUME knobl clockwise to increase effect volume or counterclockwise to decrease it.

5. Rotate BASS knob clockwise to boost low-end frequencies of pre-effects loop signal or counterclockwise to cut them.

6. Rotate MID knob clockwise to boost midrange frequencies of pre-effects loop signal or counterclockwise to cut them.

7.  Rotate TREBLE knob clockwise to boost high-end frequencies of pre-effects loop signal or counterclockwise to cut them.

8. Rotate GAIN knob clockwise to increase the intensity of overdrive or counterclockwise.

9. Rotate the PRESENCE knob clockwise to boost overall
   high-end frequencies or counterclockwise to cut them.

10. If you have the TBM95 Cry Baby® Tom Morello Wah, place it into the FX loop to recreate Tom’s totally balanced and aggressive vocal wah sweeps. Placing the TBM95 before the TBM1 will produce a subtle wah effect while placing the TBM95 after the TBM1 will create a treble-focused toe-down wah response.
