Here’s the mod for anyone who wants to add the Trem switch to their Moonn Electronics - Space Invader aka Devi Ever Rocket (Vintage Fuzz Master > Soda Meiser) 
. It’s only a couple trace cuts, some jumpers and a SPDT switch. The mod is just cutting ground to the VFM side but the trem doesn’t sound very good by itself so it only works when the Trem switch is on AND both effects are switched on. Switching the Soda Meiser off will turn the trem off. If you want to use the two effects with no Trem just flip the Trem switch off. The two DPDT switches to flip flop the two effects are no longer used.
Add a 3PDT order switcher to put the Soda Meiser first and get more high octave. Just know that if you use a 3PDT order switcher the trem switch won’t work when it’s set on SM > VFM and most of the sound will be cut if it is switched on in this order. If you want the trem switch to be deactivated when the effects are flip flopped use the 4PDT layout below. The extra pole on the switch just provides a constant ground to the VFM side when the order is reversed.
Let’s get wobbly.
Soda Meiser foot switch must be wired exactly like this for the trem to work correctly.
