3 weeks ago I bought a Kustom 36 Coupe. Tried it out at the shop, took it home and the hi gain input didnt work. Took it back to the store, the tech "fixed" it, took it home, still doesnt work. Took it back to the store, this time the tech replaced the jack and it worked. Fast forward to yesterday. Plugged it in, it doesnt work. Took it apart myself to see if there was a broken wire or bad soldering. Couldnt find anything wrong. Randomly started working again. So what would you guys do? I cant get my money back because the store has a 7 day return policy. Should I trade it in (at another store) towards something else and eat the difference. I was thinking about a Peavey 6505. Any suggestions would be helpful.
