John Frusciante’s Boss FV-50L Volume Pedalaccess_time First seen circa 2001
This pedal was occasionally seen on John’s pedalboard mainly during the By The Way tour, which makes sense since it was most likely utilized on Venice Queen. That is the only song that comes to mind to feature volume effect, mostly heard in the intro.
However, it seems that in most of the live versions of Venice Queen, for instance, at the Slane Castle, John actually uses the volume knob on his guitar to achieve the effect. So, it’s unclear whether he used the Boss FV-50L volume pedal just in the beginning, or he used it for a completely different purpose/song.
