No signal passing through pedal when not on

HPhillipsmusic

Hey guys

Just received a pedal bought on here. It's a double tracker from Keeley. Plugged it up to my power supply (Walrus Audio Phoenix) and although it works when the pedal is engaged, no signal is passing through it when it's turned off. Have tried it in my chain on my board and also just going straight into it guitar - pedal - amp.

Any suggestions? I'm sure I'm overlooking something!

Thanks

The switch is likely at fault if it's a 3pdt. Have an internal photo? 

HPhillipsmusic

will get one now! thanks

Am I safe to just lift this circuit board up @Winny_Pooh ;? It seems pretty well held down, is it just a case of carefully levering it up?

Thanks

Looks like your switch is directly soldered to the board, so it will probably not lift out without unscrewing that from the top first.

Thanks @steer I've removed the switch, it's loosened up but I still can't get it off - could the knobs be soldered too?

I’d probably message the seller on here if you have just received it....before you destroy it

HPhillipsmusic

Yes of course have done that! Was hoping it would be something I could resolve (cable/power supply/some internal switch etc.)

PSU input looks like it is also soldered directly on, as might be any pots - you probably have already thought of that though?

I hope this isn't insulting your intelligence, but have you tried setting the SW1 dipswitch 'up', for mono? It looks like it's currently set 'down' for stereo, and if so that may do odd things in bypass when you plug a mono cable in.

If it's not that...

If it works with the pedal engaged then it cannot be a power supply issue. If it's directly-switched true bypass then it's the switch. If it's relay-switched then it will be the relay - I would guess relay switching is more likely since it has a stereo mode.

Either way it will be a fairly serious pain to work on. To get the PCB out you will need to undo all the pots, the jacks and the switch.

Hi mate, hopefully you got my pm back about this, I think it'll be the SW1 switch being down as ICBM has suggested. I was using it in stereo mode. Hopefully the link to the PDF I sent over will help getting it set to how you want it.

Thanks

HPhillipsmusic

Thank you guys,

@ICBM you absolutely should insult my intelligence! I had no idea that I was even looking at a switch there! I will have a play when I get home and hopefully that will sort it.

Thanks for the help.

That fixed it, thanks guys, appreciate the spot!
