Vorzuge amp duo in very good condition. The batteries are rechargeable & need to be replaced. If the amp sits unused for a few days it will need to be charged. Batteries are 29.00 on vorzuge website but I think you could use aa rechargeable batteries. The sale is for amp & charger cable only. One of the best portable amps I've heard. Pay-pal only, fed-ex shipping tracked & insured.
