Very successful test on a Fender Hot Rod Deluxe combo V1. This lamp provides more extensive than the Ruby I love sound. Its clear, the sound is gaining consistency and balance across the frequency spectrum. Acute, including gaining musicality with a higher density and greater wealth. In "drive" mode, we find that higher balance decorated with a good heat. The gain appears to be higher and the grain more "open".
A great lamp advantageously replace a 12AX7R the same sorter.
Euroguitar is particularly well positioned in terms of price on this model.
