SWR 550X bass head, and Avalon acoustic/bass preamp for sale, both in a hard rack/road case. Both components in like new condition, rack case used but fully functional. All must be sold together. This is my backup bass head, and I no longer need it! This bass head has HUGE sound and the Avalon preamp (used for the past 10+ years by Geddy Lee) gives your bass sound a warm, fat tone. Total package is worth around 900, I'll sacrifice it for 750-contact Rich @ invisiblesong@yahoo.com SERIOUS inquires only pls.
