JHS Pedals Summing Amp

I use this to plug two guitars into one amp. Works perfectly - there is no cross-talk between the guitars, for example if you turn one down it does not affect the other.

I used JHS Buffered Splitter to split delay signal into Dry and Wet (with a muter + volume pedal for the Wet signal) and then merge them back together using this JHS Summing Amp. Works perfectly well, constant part of my pedal board. It’s attached under my pedalboard, I even forget it’s there which is a sign it does what it should, not more, not less.
