markbunney Posted October 10, 2023 Share Posted October 10, 2023 I have just purchased a used Tech 21 YYZ Geddy Lee off eBay but it only seems to work with a battery and not the mains. I am using the official Tech 21 DC9 mains plug that I have from another Tech 21 unit, so I know the power supply is fine. I love the pedal, and got it for a good price but I am reluctant to keep it if it can only be used with batteries. Does anyone have any suggestions before I have to return it as faulty???

Baloney Balderdash Posted October 10, 2023 Share Posted October 10, 2023 (edited) Get a power cable to attach to your power supply with a 9 Volt battery clip, or just solder a 9 Volt battery clip to the cable from the one spot power supply, problem solved.

Tech21NYC Posted October 10, 2023 Share Posted October 10, 2023 It's most likely a burned out component due to an over voltage situation. It can be fixed but then the good deal on Ebay isn't such a good deal. My suggestion is to return it to the seller for a refund. If the OP wants to contact us we can tell them what component to replace. It involves removing the circuit board. Support 2 1 Quote Link to comment Share on other sites More sharing options...

It was described as brand new, and only opened to test that it worked! He must have only used a battery to test it! Ill keep my eye out for a new one with a warranty Quote Link to comment Share on other sites More sharing options...
