Shower room echoes you haven't heard since the 50's recordings. A treat. Add a little 'slap' to your harmonica playing with this new Mini Effect from Danelectro. Provides similar echo effects as the Dan Echo at less than 1/2 the price. The small size is easy to pack in your case as well. Two controls, mix and repeat, allow you to adjust the amount of echo you add to your playing. Really 'fattens up' your sound. Runs on 9 volt batteries or a 9 volt adapter. Size: 4 inches deep, 3 inches wide, 2 inches tall, weighs about 10 ounces with a battery. Has earned the 'GuitarPlayer® Editor's Pick' award.
