I have a behringer vintage phaser and it's actually really good but the only problem is that there's a volume drop. Can I fix this and would a power supply help?
MY MXR pups up volume. Its annoying. When i activate it, volume comes back to normal and when its not activated my volume is freaking loud unless i disconnect the pedal... What can cause this?
To buy:

Line 6 MM4
Voodoo Lab power
Mesa Boogie Single rectifier
Boss TU-3 Done
Shure SM58 Done

there is probably a resistor that controls the gain of the pedal. changing the value of the resistor should fix the problem, however without looking at a schematic i dont know what resistor you should change. ill see if i can find a schem and figure it out.
