It can get expensive as you can only use a relic'd guitar if you are using backing tracks and you have to spring for auto tune for the vocals as well. Fake music and fake mojo ain't cheap! Karaoke is fun, but it is not live music. All improvisation, spontaneity, interplay, etc. is lost. Only you can decide if you are good with that, i wouldn't be but i also don't make a living as a musician. We get paid, but it would be a very sad salary after expenses. I admit if i did, and it got me more gigs with less people to pay... I probably still wouldn't but i get it. Folks, we are the last group standing between true live music and computer everything. We are going to lose, but we can keep it alive as long as we can. There are some folks listening who do get it.
