Rockband Guitars for Nintendo Wii for Parts

Selling both guitars for parts, one turns on and lights up but I don’t have the dongle to actually testing it. It also has no battery corriosion on it, it’s super clean. The other guitar did have a lot of battery corrosion and when I tried to clean it, one of the metal springs broke on the battery cover. Don’t have time to get a replacement, take both guitars as is. Will be shipped out within 24hours
