Pigeon MK1 DOA help

Post by ematt » Fri Sep 07, 2018 2:22 am

Found a used Pigeon MK1 on the interwebs for a fair price and pulled the trigger. Arrived 90 min ago, and...

NOTHING :bangs head:

Signal when bypassed, new batts, just dead when engaged. Hate to send it back without even knowing what it sounds like. Footswitch? I have a meter, just not sure how to go about checking it or anything else for continuity.

Might be some bare wires touching another conductor, as Jim suggested. I had this happen before in a similar Mk1 on arrival too

Thanks for the replies, everyone. I’ll take a closer look today and see if any of those suggestions are the case.

Give the footswitch a few quick on and off hits and also see if it engages when switching it on and off slowly.

A friendly talking to may also help. :badteeth: :hihi:

They sound ace though, mean and racous! :freakout:

Ok, I gave it a good look this morning, and this is what I found...

The circled area’s solder joint has broken, but the good news is when I touched them together it came alive!

The problem now is that I have someone flow a new joint as I’ve never done it. It’s just hanging in of its own accord.

Philip is correct. This is hands-down the best fuzz I’ve played so far. I can’t believe how epic it is.

Where are you based? this would be a v quick job for someone with a soldering iron. I'm in E London for instance. If you were nearby I could do it.

NW Florida. There is a local tech who I might trust, but he can be a bit hot and cold.
