I recently just started to experience a similar effect. I play guitar. I've had the unit probably 4 years never a problem. But lately, my volume gets cut and sounds a little muffled. Then it suddenly comes back up. I was wondering why. After reading this I think it is the transmitter. Do I need an RMA for something this old or can I just take to the service center which happens to be 1 town over? Also, on a different note and having no idea where to go for an answer I can not change my email address. I put in the pass word and I get an error. I click send a confirmation email and it takes me to the next page but no email shows up. My email is my own personal business account. Do you have problems accepting such email addresses?
