Hi
Thanks for the reply.
I’ve set my HD to Line on the 1/4” out and 3.5 impedance but it’s still doing the same thing. On the back of the MDR there is a Loop Level, but even with this set to almost nothing the same thing happens. In desperation, I tried it the old fashioned way -HD to the front of the amp, but I can’t deal with distorted delay and reverb!
