Today going in to do some writing my SV mkii hd100 kept automatically going to 0. I noticed when going to editor, when i turned my volume up there it works fine for under a minute. Just the volume would go back to 0 and looking at the amp the knob settings show up on the display everytime it does it. Couldn't find any issues like this on here just the opposite when it spikes but controlled that with the express pedal/patches, my head is about 2yrs old or so i've had problems but nothing that didnt fix itself after turning it back on. Have a show comming really don't wanna cancel 'cause of this.
