||Making the MXR Distortion + Louder|
Does anyone know how of a mod for the newer style MXR Distortion plus pedals to make them louder?

Replacing the clipping diodes with ones of a higher voltage drop, like LEDs will work.
Blue will have the highest threshold, and therefore highest volume. (i think..)
Put it onto an 18V supply by using another 9V if you find the pedal becoming less distorted, this will allow the opamp to swing further voltage wise, and make more distortion.

The schematic for the older stock Dist+ lists the output pot as 10k. In tandem with the 10k fixed resistor in series with it, this provides an annoyingly low output level, even when everything is maxed. Replace the output (if it is currently 10k) with a 50-250k pot (100k is probably good). This will increase the output level. When combined with the suggested diode switch (2 Si diodes instead of 2 Ge diodes) this will also increase the overall output level.
Please note that switching the diodes will also reduce the amount of clipping available at any given distortion pot position.
