If you are after the 70?s Phaseshifter sound like the E.H or MXR type of Phaser, you can?t go wrong with the Behringer VP1 Vintage Phaser. It deliver?s "a to close for comfort" sound of the classic phaser fx you need, at a steal pricetag, higly recomend it for all sorts of situations when you want that swooshy pleasant spacey sound, from your guitarr of keboard or synthesizer,...or what ever, why not try it on your trumpet or violin, heard on that 70?s recordings :D
