Hi everyone, I noticed something rather strange with the line out of my krank revolution 1 head: its sound changes if the speaker output is plugged into a cab or a dummy load [weber mega dump]. It loses a lot of highs and lows and gets tons of more mids. I uploaded a few MP3s to show you exactly what happens: 1. mic in front of cab [I used this mic position to create the impulse I used below] http://www.metallian.net/vladimir/krank revolution - cab.mp3 2. line out [amp unloaded in cab impulse applied on the raw track] http://www.metallian.net/vladimir/krank revolution - impulse - direct out [cab unload].mp3 3. line out [amp unloaded in dummy load impulse applied on the raw track] http://www.metallian.net/vladimir/krank revolution - impulse - direct out [megadump unload].mp3 Here is the gear used: schecter blackjack [modified with EMG 707, since they don't do lefthand hellraisers] maxon od-9 overdrive krank revolution 1 series mesaboogie 4x12 standard shure sm57 Has anyone an idea of what happens here? I thought the dummy load should just unload the amp and not influence its direct output sound. Has anyone already experienced it? Is it just the krank that works that way? Do you think it is due to the weber's mega dump? Should it work better with a thd hotplate? And finally, does this mean the mega dump could damage the amp? Thanks for your help!
