Solution to Popping Switch Sound of M-wave Mini Universe!! 

My unit hasn't arrived yet but if I experience this problem I plan to run it through a basic single-line loop switch pedal. Loop switchers redirect the signal chain and can be used to remove and reinsert pedals when engaged or disengaged. From there I can keep it on at all times and engage it with the loop switcher, avoiding the need to depress the Mini Universe's foot switch.

They are now selling the second version of the mini universe, they fixed the clicking problem, the new version has significantly redesigned the board and removed the true bypass

1 is efx in and connects to 8 , 2 on indicator LED ,3 efx out 4 is input 5 ground 6 output And jumper 7 to 9 this is common 3PDT footswitch diagram. But there are others look for 3PDT Wiring diagram

I added 1M ohm resistors then replaced it with 2.2 k ohm resistors as shown but i noticed a drop in volume when the pedal was used compered to bypass mode. The effects pedal was used in front of the amp. Having tried it again through the effect loop it sounded better, by the way both resistor values removed the popping sound.

Thank you for your lovely information

This reverb pedal needs tails! But fair enough for its price and can still be modded

I´m gonna try as soon as I discover how to open it !!! kkkkk Thanks !!!!

very good man, will try the 2.2k, the pop is the worst problem. but did u find how to fix the delay without messing the led?

What to do when the pedal comes with a 4-pin switch instead of a 6-pin switch as shown in the video?
