Hello, this is my first post around here. I don't know exactly if I'm posting in the right community, but I've seen that there have been before discussions so I said I'd give it a chance. I have a problem with my freshly bought amplifier, Fender Blues Deluxe Reissue. The sound itself is amazing but, on the clean channel, the master volume seems to have no effect whether it is at full 12 or at 0.(on the drive channel both the channel volume and the master work) By the channel volume I can get from very mellow perfectly clean tones to somehow cranked crunchy tones at around 12, but the master volume has no effect at all, no matter if I'm on any of the two inputs or if the bright switch is engaged. Please help me, I want to know if it's anything that I can fix at home or I need to find somebody with a steadier electronics luggage of knowledge. Thanks in advance and sorry for my bad English! All the best!
