I have a Line 6 Spider II 150 watt which I bought a couple years ago when I thought effects were cool. Now I want to get rid of it for something that'll give me a nicer sound. How much should I sell it for? It's still in practically new condition btw.
As much as you can get. Check completed listings on eBay e.t.c
Ebay or craigs list would be a good place to find the normal price. As Yngwi3 said, as much as you can get for it. Ask higher than your really expecting since your bound to get talked down.
