The tc electronic 3RD Dimension chorus pedal. It's an intuitive and easy-to-use chorus pedal that lets you select the chorus effect with its four mode switches. Each of the four modes produces a beautiful chorus sound, without any harshness. It's fine to leave it on all the time, and it works subtly well in recordings. True bypass footswitch. Can be used with electric guitars as well as acoustic guitars. The product is in excellent condition, having been used lightly at home since this spring. Includes original box and instruction manual. Please note that all sales are final and returns are not accepted. Thank you for looking.
