Hi, I meet this problem too. Do you know how to solve it now? Is there any solution?
Thank you for help~
My 44 Magnum amp pedal works and sounds great with my Roger Linn Adrenalinn 3 pedal and my Mesa 1 x 12 speaker cabinet (8 ohm – 90 watt Celestion). But when I connect the Magnum speaker out to my Palmer PDI-03 input (speaker load box), the signal goes silent every 20 seconds, cutting out and back in again. Of coarse all connections are secure and tight, so I know there are no shorts. What could be happening and why? A tech in my town mentioned that the Magnum was a class “D” power amp, and maybe this could be the reason? The Palmer PDI-03 is a very popular load box used by many professionals for LIVE sound application/direct recording, etc… and works incredibly well with all amps, including Marshall, Mesa, Fender, etc…
Thanks.
