RE: the Zoom 505 multieffect pedal--it's a pedal that's one of the most reviled by the effect intelligentsia  (I happen to own one :-), they were only $30 USD online at the time), but it's pretty cool for a beginner. A big bonus--they work great as a headphone amp, just plug your electric in and no one else can hear.

Good patch cables cost $5 or more, and good guitar cables about $10-15. Yeah, there must be a young aspiring musician who would appreciate the donation...

I'm most sorry to hear about your friends son (in more ways than I care to list or share). I'd like to suggest giving it to a friend the son my have played, rocked out, jammed, practiced, learned, or shared his talent with. It is amazing what one of those items could mean to a friend. SERIOUSLY.......from squabbling over an item, repairing an item, meeting the first time, or even being hit upside the head with one of them. Its worth the legwork because I bet more than his parents miss him as well........ I guess my point is this: I felt horrible selling my Dad's "stuff" to pay for his funeral and the smiles I got giving his worldly possessions away.....F'n priceless!

That second picture has the word "distortion" on the far right so I would guess a fuzz box of some sort that creates different sounds from a guitar feed. Much like the lever on an electric guitar gives that waa waa sound this may have several sounds it can create.

Guitar pedals, tuners, cables and a power supply for one of them.

Looks like a collection of guitar tuners.... but then again, I'm no expert on that. ;-)

They are mostly older model electric guitar accessories, so maybe ebay and you might fetch:

zoom 505 guitar multi-effects pedal $15
dan-echo echo guitar effect pedal $50
unknown guitar tuner $10
Korg GT-3 guitar tuner $15
patch cords and whatever the power supply wall wart, not worth the shipping

Find a high school kid that just wants to shred on their electric guitar and give it to him/her. New digital effects pedals now combine all that stuff and more under $100.
