OVERALL OPINION

The sound has lost a bit of its grit after one year of use. I just bought a les paul tribute epiphone and I was a bit disappointed with the result, compared to when I tested it in the store. After doing some research on the Internet, I decided to retube the amp. A local store gave me some info and I went for it. The bias setting is automatic, you only need to have matched tubes for the power stage. I used two 12ax7 groove tube gold series for the preamp and two JJ El 34 power tubes. And the sound is now amazing, I rediscovered my amp. Warm sound with a crystal clear pinch for the fender strat, the overdrive is better defined and with a nice crunch with a low gain. Don't hesitate modifying the amp when you want to give the amp a new life. The re-tubing cost me $80 for the groove tubes and $65 for the JJs. ... Not cheap, but I don't regret it at all!
