Could somebody check my orange squeezer layout?

[dbp512]

It seems like I've bitten off more than I can chew this time. I got the parts for a simple orange squeezer a while ago, but before I got around to building it I found schematics for modified versions that had attack and decay controls. I quickly abandoned the original in favor of this, but unfortunately there were no vero layouts. I decided to attempt to make one myself, and after several revisions I eventually found one I thought would work. I finally finished it, but the only noise I can get out of it is a repeated clicking sound. I'm not sure if the problem is in my soldering/assembling, or if the vero layout is to blame. If somebody could take a quick gander at my layout and check it out, I'd be grateful. I'll update with the voltage of the pins, but since I have my computer on hand and the vero is suspect as well, I figured someone might find the problem already.

R1 should be 4M7, not 4k7, as on schematic.

is it possible that the stop-hole (can't remember what they're called) you drilled in the vero, just below the IC, for a ground connection to pin 4, has also prevented the jumper from pin 4 touching the ground strip?

also, for what it's worth, i'm not sure how many vero boards you've made but they are just about the most failure-prone way to hook everything up. that's not a dig, just sayin' that you might find other ways of making boards less troublesome (after the learning curve)
