Customer Feedback  "The effects loop sounds and works exactly the way an effects loop should. There is no noise and the loop is totally transparent to the overall tone of the amp." - Jason Rowland, Harmony Central Reviews

Customer Feedback  "I had a HG-Jose Mod performed on a reissue 50 watt plexi that has a solid state fx-loop. I had Voodoo put in their Inturrpt FX-Loop and it sounds tend times better than the stock solid state loop." Jarad Foster, CA

Customer Feedback  "The loop kills! I was running the delay in front of my JCM800 2204 and it was never right, same with the chorus. Now the delays and chorus sound like they do on CD. They are far more controllable and sound more pro." - Ben Johnson, OH

Customer Feedback  "The amp is a Marshall 2203 single channel and I wanted the loop so I could insert a clean boost pedal to boost the volume of my solos. Works like a charm, yeh!!!" - Craig Tucker, TX
