I have a HD500x and a DT25 and I absolutely love the sound, flexibility and control of the two of them. However, I sometimes have a problem with the HD500x display switching back and forth between the signal chain and the amp knob controls. Sometimes when this happens, all the foot switches stop working.... sometimes I have to press them several times and then they will work. I don't think the knobs on the DT25 are moving (which would cause the display to change) because they stay the same. I thought it might be the tubes going bad, but I just put new tubes in and got the same behavior.
This only happens when using the l6 link to the DT25. I use the HD500x when I play acoustic hooked straight to the PA and have no problems.
I was wondering if this has happened to anyone else.... Thanks in advance for any help!
