The Compressor works smoothly and is better than most boxes. It works best where it's needed, when using a pick or slapping. The Drive control is a joker in the game. Here you can get one of the tube amplifiers advantages -the great distortion character. An all-tube head of course has better dynamics, but EBS is very close.
Careful settings liven up the sound without adding distortion.
Slapping on a Jazz Bass sounded awesome with the Drive knob at 12 o'clock. The Character button gives the sound some more distortion. In this mode, the tube's natural compression also increases. Using a pick with distortion and a lot of treble sounded full, but still punched through. Fafner is a powerful amp that can produce some loud sounds.
