DR Strings Electric Acoustic Guitar - Zebra™ Medium-Heavy, ZAE-13star rating 5JOHN SWEENEYOctober 27, 2009This was the first time using the above strings. I was really impressed by the clear bell like tone and the increase in sustain without the use of amplification. I use these strings in combination with a Taylor solid wood jumbo guitar and the LR Baggs M-1 acoustic humbucking pick-up. These strings take on another dimension when used with a magnetic pick-up, the stainless steel in the strings assures a very deep bass and clear highs. I especially like using the medium gauge strings with standard tuning a 1/2 step down (E to Eb). The sound is unbelievable!
