Re: Rent the backline / buy the backline ?
I bought just enough decent backline to cover those occasional church / wedding band / small touring acts that request "a drum kit" or "a bass amp." It was all from craigslist so it was pretty cheap, and since I purchased it, there have been many instances where I get a call the day before the show asking if I can provide something last minute, and I just have to toss it in the truck.
a Yamaha Stage Custom drum kit
an Ampeg SVT-410HLF with a basic GK head
a Fender DeVille 212 combo tube amp
a Yamaha MO8 88 key weighted keyboard
You'll end up chasing your tail trying to own everything. I'm good friends with the local backline provider so I get all my twins, jc-120's, dw kits and stuff from him. So far the above listed gear does a fine job for the level of acts requesting it.
