Not to long ago I bought a Fender Blues Deluxe. I was super impressed with the quality of the sound and the amazing tone that can be obtained from it. Not to mention the great reverb for which this amps are known for. Then it started To rattle at certain frequencies and I started to get concern. I Tested the tubes and they check good. I found that one of the 12AX7 have been replaced with an ECC 83. Not worrie it is a direct replacement and it checked good. I was getting upset. I started to look for possibilities and it seems to me that it was mor pronounced at higher volume. This pointed me to te speaker. I temporarily replaced it with the speaker from my Blues jr and it checked good. I got more upset and frustrated but them remember I had 45 days to return it, so I drove down to GC. The people at GC did not even care. They were quick to provide me with a choice, they did not have other use one but either return my money or I could pay the difference and walk out with a brand new one. No only that but they knocked off $100 of the new one, so I payed an additional $108 with taxes and off I went. Hey! It was cheaper to upgrade to a new one than buying a new Celestion speaker. A yeah and I was happy again. This amp does not need further review. It is just great, with a superb clean channel and nice over drive channel. Great amp for Jazz, Blues, Rock and Classic Rock. It is pedal friendly. This amp was built on Nov 2016. The tweed cover is slightly darker than my previous one. A plus if you ask me, as it will hide the dirt better than the old one. The foot controller it's different than the previous version too. The old one Different tweet color and the peda whatcha is slightly visible to the left notice the difference .
