http://www.zoom.co.jp/english/models/StompBox/pdmodel.html First off, forget about those cheesy multi-effects pedals that Zoom makes, like the 505, I hate 'em too. These 4 analog pedals were largely ignored, I think, by association with those multi-effects units which might be okay at home but don't belong on stage or in the studio. On a whim I collected these four analog overdrive/distortion pedals Zoom just discontinued recently and they are quite good. The Tri-metal resells quite high on eBay lately but I prefer the Powerdrive and then the Hyperlead. I like the seperate tone controls. The Ultra Fuzz lets you 'model' the effect. I use them with a Ibanez Ts-9 sometimes. These analog pedals were quite good IMO and are built like tanks. Check them out if you find them in a shop.
