The amPlug series has been renewed since its inception in 2007, with its casual ability that can be plugged in directly to the guitar, and has been dedicated to analog circuits. The analog circuit has been greatly improved, and each model has 3 modes. The guitar type has a multi-effect function, and the bass type has a rhythm function. In addition, the retractable plug mechanism that rotates 180 degrees, the automatic power off function and the usability has also been improved. With the simplest and most authentic sound, amPlug supports guitarists and basics in a variety of situations. ■ AC 30 input and output terminal: headphone out, aux in power supply: 2 AAA batteries External dimensions: 86 (W) x 80 (D) x 31 (H) mm Weight: 1.4 oz (40 g) (not including batteries); Accessories: 2 x AAA batteries for operation confirmation
