MXR Microamp vero layout mistake fixed?

[Renegadrian]

mmm maybe I am going to say something n00bish...
connecting pis 1 and 2 should be only to prevent (possible) interaction/noise/whatever coming from the unsused opamp.
usually one of the three connections goes to grd. why should it go to vref!? Also, following the tonepad layout, the 10M res that should be tied between input and the input pin of the ckt (pin 5 in this case) is connected at pin 3 instead. so my ? goes...
And the way I built it works like a charm...I guess it's easy to add that jumper on pins 1-2 but it works good even without, and pin 3 also without connection (try to ground it to see if there is some notable difference...)

thx for the reply!

Without a dual supply, this GND is the negative supply +V is the positive and Vref is "GND".
Connecting pin 3 to GND you'll indeed force the +input to negative.
The circuit will actually work with no connection on the unused pins, but the unused half might act weird since it's open and working (it receives power supply)

ok grazie Federico!!! Yeah
