Members tRagerEffects Posted October 22, 2009 Members Share Posted October 22, 2009 You should open it up and see if there are any clear component that are blackened or obviously damaged. I would repair it rather that just throwing it in a bin. Even if you had to replace every single component, it would still be worth the cost. As long as the PCB board is still good, the rest of the parts might cost you $5-10 if you had to replace every single one of them. Link to comment Share on other sites More sharing options...
Members FlyingZ Posted October 22, 2009 Members Share Posted October 22, 2009 No doubt the mountain switch failed. It's an easy fix: http://www.smallbearelec.com/Categories.bok?category=Switches%2C+Relays&searchpath=215940&start=17&total=53 Link to comment Share on other sites More sharing options...

Members WRGKMC Posted October 22, 2009 Members Share Posted October 22, 2009 Keep in mind, the polarity of those pedals power jack is reversed from most others. There is also a small switch built into the power adaptor plug that switches between the battery and the power adaptor. This way when a power adaptop is plugged in the battery is disconnected. The input jack also provides power when a jacks plugged in. All of these should be checked for continuity with an ohm or volt meter to be sure the voltage is getting to the board. The only other item I can think of may be a diode on the board that prevents board damage if a reversed power is connected. Link to comment Share on other sites More sharing options...
Members Belva Posted October 22, 2009 Members Share Posted October 22, 2009 Does it work with a battery? Link to comment Share on other sites More sharing options...
Members heyhey Posted October 24, 2009 Members Share Posted October 24, 2009 Blast it with contact cleaner. Mainly around the jacks and into the nobs. Link to comment Share on other sites More sharing options...
Members drewl Posted October 25, 2009 Members Share Posted October 25, 2009 These pedals are so easy to fix/build it isn't even funny.have your friend trace the dc power from the battery clip through the dc plug/switch, there's a protection diode in there that will not pass the dc voltage if it's bad.

Members JAYJO Posted October 26, 2009 Author Members Share Posted October 26, 2009 Does it work with a battery? It was working by battery but as the battery was dying I stupidly plugged in the adaptor which appears to be with the wrong polarity, causing the pedal to smoke! thank you all for your help.
