SHO layout

[Pedalhead]

I was looking at the SHO Compact layout and it looks wrong to me compared with the schematics I've seen. The zener diode should go to transistor source/gain 3 and not to ground.

I haven't got an account that allows me to post on the layout page so thought I'd post here.

Mine is based on Vex's own schematic from the Inventobox documentation and so we know is 100% correct.  All other schematics I've seen of the zener version had it going to source, but he's either changed that in a later version of the SHO to ground, or they were wrong.  Both ways will work fine though.

Ok, thanks, good to know. I breadboarded it last night but only noticed the diode differences today after I'd taken the circuit down. Sounds great by the way, I like the 2u2 cap on the output mod and think the circuit works best with Strat type guitars.
