MXR Distortion + (the newer M-104 Dunlop model)

Stock from MXR, this distortion effect pedal comes with a .047uf capacitor (C4) and 2 1n34a germanium diodes (D1&D2).

When I first tested the MXR M-104 Distortion +, I found this distortion pedal to be a bit thin and nasaly sounding, and it lacked my desired bottom end.  The distortion quality also sounds a bit scratchy for my taste.

So I tore into this little dude and figured out the electronic components that I needed to de-solder and change out so I could achieve my desired guitar tone results. 

My tone and distortion + MXR guitar effect pedal mod follows:

This free effect pedal modification can be done in just about an hour...  Click on the pic to the left...  The link will open a very clear instruction pic to follow.  (Please tell your guitar player friends to head over here for free mod information!)

Change out one capacitor and two (or three) diodes to open up the bass response a bit, and to smooth out the distortion.

Here's what's needed:

• (2 or 3)  1n4148 diodes  (substitute an LED for a bit more crunch)
• (1)  .22uf metal film cap  (.47uf for more bass -or- .1uf for bass)

     Feel free to experiment with some different combinations of diodes.  There are many different combinations that you can effectively try in order to achieve your ultimate guitar tone.

      (Please remember to follow all safety precautions when using hand tools and soldering irons! By performing this electric guitar effect pedal modification, you confirm that you have seen and agree with Ultimate Guitar Tone disclaimers.)
