LINE 6 POD EXPRESS for guitar. I've never used it outside since I bought it. Only used it once indoors for testing. I haven't stepped on it with shoes. Operation confirmed. It works with batteries or an adapter. It can be used as an amp simulator and also as a multi-effects unit. It also has audio interface functionality. As an amp simulator, you can experience powerful sound even with just headphones, without going through an amp. You can make fine adjustments to each effect, etc., with your smartphone. Everything in the photos is included. Instant purchase possible Questions welcome Price reduction possible within reasonable limits Thank you. #LINE6 #POD #AmpSimulator #MultiEffects #Guitar
