Fernando von Arb or simply FVA (born 17 January 1953) is a Swiss guitarist, songwriter and producer.

Around the same time, Von Arb became ill, leading to suspicion that he may have been diagnosed with lymphoma, but he is healthy now.

In 2005, Von Arb temporarily left Krokus due to tendonitis in his wrist to be replaced by Mandy Meyer.

However, by 2007, he had returned and was able to reunite the four principle members of the group's classic line-up (featuring himself, Storace, Von Rohr, and Freddy Steady).

Von Arb and Krokus released Dirty Dynamite on 5 March 2013 with minor success in the US, but a major hit in Switzerland.
