In the for-what-it’s-worth department, I was about ready to chuck my Blues Deluxe. Not only was it unholy loud, it was just shrill and unmusical at times, with either ear piercing highs or a sloppy bass at volumes you would like to play. I toyed with the idea of a speaker swap, but after seeing many comments about changing the V1 position 12AX7 tube for a 12AY7, I spent the twenty bucks, and the amp instantly came to life for me. It is not just the more manageable volume control; it is the tone, which, on a Tele single coil neck pickup, is creamy smooth and like nothing I’ve heard out of my guitar before. All pickup positions are incredibly clear, and my added fourth position, which is a series combination, now sounds like a blues monster (before, it was sometimes a muddy mess). So, if there are any more BDRI owners out there who are less than thrilled, you might try this cheap upgrade.
