Hello there. I recently took a gamble on a black, small font small stone. When in bypass, the signal works great, but when the effect is engaged there is no sound at all except for when the color switch is up and you can hear a very quiet signal passing through. You can also hear the sound of the guitar cable being connected to the instrument with both the color up and down. I have a feeling there may be a thread about this somewhere but I can’t seem to find any answers. Any help is appreciated as my skills are not the greatest, to say the least.
