I recently had the mainboard replaced on my DT25 by a Line 6 certified repairman. The amp sounds great. I noticed the amp was in Low Volume mode. I put the amp on stanby and switched it to normal. No volume basically.
I spoke to the tech and he basically asked me to speak to Line 6. He is unclear whether this could be a issue with the replacement part. He also admitted he is trying to eliminate user error. ;)
I am hoping this is just a symptum of a failing power tube .. Before I open a support ticket .. I was wondering if anyone has experienced similiar symptums ..
Thanks in advance !!
