Boss TR-2 Tremolo Model Tremolo Effect (1997), made in Japan, serial # AK24835, green enamel finish. There are few pedals more recognizable and universally beloved by guitarists than the Boss line of effects pedals: affordable, produced en masse, and offered in a (now) classic array of bright colors. The TR-2 was Boss' tried and true Tremolo in a little green box. Only three knobs are needed here, one for rate, wave shape, and depth of the tremolo. Like other Boss pedals, this sturdy effect is built to run off a 9V power supply or battery.
 
Height is 4 3/4 in. (12.1 cm.), 2 1/2 in. (6.4 cm.) width, and 2 1/8 in. (5.4 cm.) in depth at deepest point. This pedal is in overall clean cosmetic condition with only minimal signs of use here and there. There is a small piece of velcro for attaching to a pedalboard on the back, but this could be easily removed if desired. This pedal comes with its original box. Excellent Condition.
