To me the ES2 is better than all the K&K pickups, LR Baggs and Fishman I’ve tried and I’ve tried about 12 different ones between those three companies. The ES2 has way less quack than all those to my ears. Having said that I will only plug an acoustic in if I’m playing with a large band that is loud and then I use a Fishman Aura Spectrum with mic IR’s. Otherwise I always use a mic. There is no pickup that compares with a good mic in front of an acoustic to me.
