Customer Feedback  "If you are serious about your effects and do not want to compromise your tone then go with the Tube Buffered FX-Loop or upgrade to the XL version. I checked out the work inside and it's impeccable." Ray Weber, WA

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

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  "I have done the route of trying other amp mod techs and the FX-Loops were less than ideal for my needs. I read all the reviews and gave it one last try. Trace nailed it perfectly! This loop is light years better than anything else I have ever tried and I've tried tons of loops." Eric Tyner, 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
