Pulled the trigger for an RM100 mod.
Since I also live in Berlin, I really got my hands on the mod fast.

It comes with a good pictured description.
It takes a little while but is not difficult to carry out. No drilling.
You just have to manage all the screws - something Paul also has been thinking of.
So if you have ever opened up a tube amp before and soldered before, this is a no brainer. It is as easy as taking the amp apart, exchange the MIDI board, place just very few soldering points.
The most difficult part is to move the amp chassis back in the wooden housing if you are alone. :-)
If you are unsure: Any technician should be able to carry this out with ease, since the description is accurate.

But best of all: It works!

* I can now manually switch between channels of Egnater and Synergy dual modules. Two presses needed to pass by a single channel module.
* fast MIDI switching between all channels (consider a new MIDI controller - the Randall one has only three buttons )
* the original Randall footswitch is still phantom powered.

Awesome. I am guessing, the RM100 suddenly is ...whow!

Thanks for making this happen! :D

As requested a video presentation of the RM4 dual channel mod is online now. The RM100 will soon be followed.

Just installed my RM100 Dual Channel Kit today. Super happy I can now use both channels on my Synergy modules. Yaaaaaaaaaayy!

Just an FYI - I just did the RM4 2 channel midi mod myself. I am an almost complete beginner to soldering. My experience to date was I soldered two xBox mods 18 years ago (and messed one of them up), that's my level of experience. After watching a couple of random soldering youtube videos I was able to do the install myself without too much effort. If I can do it, any careful individual can do it.
