I LUV this AMP!!!It is very warm, has great effects and I PROMISE you this is the best sounding AMP I have every used. I rate this above Mackie Reach, Mackie Freeplay or Fishman SA220. The only thing this AMP needs is some Bluetooth. The Reach and the Freeplay are one up on this feature.....This AMP is superior in sound, portability and people love it.
