Pro Guitar Shop Site
Just found this site where you can build your own virtual pedal boards and listen to how it would sound prior to purchase. It's a prretty cool site. You can hear single pedals and effects and amps for that matter. I've only just started looking around but seems pretty good. Will have a better idea after a few more visits.
Teamwork- A few harmless flakes working together can unleash an avalanche of destruction.
