Customer Feedback  "If I adjust the Send and Return Levels I can literally make any pedal sound nothing short of stunning. This is truly an accopmplishment as I have the Dumble Dumbelator and your loop more than holds it own against the Dumble." - Rick Ashster, TN

Customer Feedback  "An all Tube Effects Loop complete with Send and Return controls (THE BEST LOOP I HAVE EVER HEARD PERIOD). Whether you are using effects or not, this feature alone is a massive tone shaping tool. Thanks guys, more amps will be on the way!" - John Bachety, NY

Customer Feedback  "If your looking for a transparent tube buffered effects loop then this one will do the job. I don't know how they do it but Trace really hit this one right on the nose. This effects loop sounds awesome, delays, flangers, chorus sounds awesome and as far as the tone being different when you plug into the loop, I really cant tell a difference in tone. That's what you call  transparent and let me tell you I am a tone junky. If there is a difference in tone I will be the first to tell you so if you are thinking about putting this loop on your amp don't hesitate. Spend the money because when you get it back you'll be glad you did. Trace congrats again on a job well done. Rock on." - Fred Storage, MI

Customer Feedback  "I also Got the Deluxe FX Loop, that is tube driven... Effects are very warm and expressive with this mod. If you are up in the air about getting your baby modded. I'm telling you, Have No Fear... Voodoo Is The Place! Thank you Voodoo Amps. I AM *REALLY* HAPPY!" - Tony Bruno, NY

Customer Feedback  "With over 50 vintage and modern effect pedals as well as various rack mount units it's damn near impossible to find a loop that will work with everything. This tube buffered XL FX-Loop is INCREDIBLE! It's dead quite and has an unbelieve able amount of recovery gain on tap. Aside from this the loop is oustandingly transparant." - Rick James, CA

Customer Feedback "The Eventide Eclipse and my Lexicon reverb units sound awesome through your loop! A friend of mine has a TC Electronics G-Major and much to my surprise it makes this thing punchy and velvety." Harry Thrumble, UK

Customer Feedback  "The FX loop sounds great! Very full and versatile." - Marc, Harmony Central Reviews
