I need some help Identifying the part marked Part # Q13556, in the reverb circuit. I believe it is what activates the lead function on the amp but I can;t figure out what it is, or how it works. Thanks

I'm not positive but I think it may be a Single Channel switching Optoisolator.

Check here for it:

I read 013556, Fender's standard ref for an LED optocoupler.

Thank you both, I suspected that might be what it was because of the -6.3 volt input on one of the terminals. However it looks to be like it would be grounding the wet side of the reverb mixer, muting the whole signal rather than activating the lead. What am I missing?
