The Vari-Chain System.  The world's first all-right-angle, configurable-length power chain cable.  No more unused plugs to short out.  Combine 2x, 3x, 5x cables to configure any length.  Only the last plug on each is straight, to help continue the chain.  Cap off the final plug with our 21RAA right-angle adaper.  12" between all r/a plugs when chained (6" to the straight end-connectors). REMEMBER:  When figuring which Vari-Chain parts to buy, one straight plug is used up every time you add to the chain.  So 3 x Daisy3R yeilds only a 7x chain, not a 9x chain. Power chain cables allow you to use fewer power supplies.   Most 9VDC supplies will deliver enough current to power several 9VDC pedals.  For more, see Power Chains.
