Buffered pedal with activation switch problems. Help Please!!

[alfonso_bundis]

Hi everyone,
A friend came to me with an Ibanez cm-5 classic metal pedal. Apparently the bypass switch is not responding properly. Since this is not a true bypass pedal I have no Idea where to start. Any suggestions? I was thinking of converting it to true bypass, should I remove all the buffer pieces to do this?
Thank you in advance for the help.

1) make sure the little switch inside is not worn out!  That's the most common issue, and is very easy to fix if you have soldering skills.  The companies usually sell replacements, or you can find them on Ebay.  Just measure it and look it up.     

You could take a look at some stuff like this: https://solgrind.wordpress.com/2009/04/15/true-bypass-for-boss/ if you want to take it further than just fixing the switch.   

IMO, If the pedal has an internal buffer I would not worry about converting to TB, myself.  That is what the buffer is for.  The cost/benefit isn't there.   YMMV

Is it stuck on? of stuck off?

Some of the other guys know all about the boss style bypassing. I'm not one of them.

If it's stuck on. You have the option to build a true bypass looper.
Google is your friend, Beavis Audio has a diagram for a true bypass looper.

Tadaaaaa

You can test whether or not it's the switch that's broken by shorting across its connections with a handy electrical-continuity-activation-implement (screwdriver).  If the pedal turns on/off with each short, then it's the switch.  If not, then it's the flip-flop circuitry.  You can read about this at Geofex.

Or with any tool you can find in your grandma's silver tea set...

How very retro of you!

Classic/boutique pedals must be treated in some kind of retro way..

Thank you all for your replies!!! I will check the state of the switch and decide how to proceed accordingly. Kipper4, the true bypass looper is a great idea!!! Thanks for the schematics.
