This used Ernie Ball Volume Pedal the industry standard for all guitarists. This is in great condition.

This is a very rare and much sought after classic Boss flanger with oodles rich, lush flanging effect. The first flanger effects pedal from Boss was the BF-1, sold 1977-1980. These were made in Japan and used the same enclosure as found on some of the older Roland pedals (AP-2, AF-60) from the mid-seventies.
