definitive answer on an effects loop for the AO-28?? to affect the whole organ

[aaronz28]

I want to install an effects loop on my B3 -

the Trek version would be great -except as has been said - it only affects one manual -

i want both and pedals

Has anyone created a smooth way to do this that isn't terribly invasive?

Thanks

That looks like a great piece of kit!

Has anyone tried the Mojotone FX loop mentioned and if so, where did you hook up the power supply for it? I've tried the red dots for B+ (in the attached image), but it affects the signal strengh even if I bypass the fx-loop.
