Query: Recoton DC Adapter / Excellent !

I Purchased This DC Adapter For My Guitar Effects Pedals, And It's Perfect. It Replaces The Need For Numerous, Expensive, Product-Specific Adapters, And It's Easy To Use. The Recoton Unit Includes Both Negative-Ground, and Positive-Ground End-Plugs; And For Most Voltage Settings( Did You Know That Many So-Called 9-Volt Products Actually Use a 7.5-Volt Setting?). The Recoton DC Unit Is Defintiely Worth The Cost!
