I never have to invest in a tremolo for each of my guitars I only need this pedal, the Behringer us600 and I now never have to worry about going out of tune because Im just using my foot to do whammy effects and it can sound different depending how I play and press my foot on the pedal and the sounds are realistic and combinations of setting the pedal are many a very valuable pedal to have at a great price even if your guitar doesnt have a tremolo you can rock like you have one and more!!!
