While I am working on my marshal amps and repairing them, i need a cheap replacement to get me by. I found a Line 6 Spider III 30W Mono 1x12 for a 100 dollars, the guy says he bought it years ago for a friend and has leess than 10 hours of play time. Also Found a Fender Mustang 3 excellent condition. 100 Watts, 12 inch Celestion G12T-100 speaker, Includes 2 button footswitch. Asking 175.00 dollars. They are both equal distance away from me about a 45 minute drive. I am just curious, what do you guys think is the better amp/deal? And Is there anything i should be aware of... or look out for with either model, when i go to pick it up and test it out?. like any sort of common problems i should be aware of? I realize they are both solid state, and well my two solid state marshals just died on me a few days ago, so Only thing i can think of is playing for a good 5 minutes with some over half way loud volume to make sure nothing is over heating or going into protective mode or blowing the speaker lol. I will also be using a zoom G5N multi effects on which ever amp i decide on if that matters. And i know the Fender has an effects loop so that's a bonus. Any thoughts?
