Just got a Trademark 10 and the reverb isn't working at all. Any help or suggestions would be much appreciated. I bought it used so there's no warranty.
I would suggest you try calling Tech21 tech support and talking to one of their techs directly. They helped me out a while back with a speaker issue I was having on my Trademark 10, without asking for any warranty info or anything. Get their phone number from their web site, and you'll be good to go!
