completed my headtrip 2 build and it no workie.  dry pot works and can hear a pop when changing patches.  No effect tho.  Wet pot turned all the way up.  Voltage are all correct except pins 5 and 6 on the eprom read 0.  Pin 14 and 15 on the FV-1 are both 3.3vdc but 5 and 6 on the eprom are 0.  The pads for pins 5 and 6 on the eprom read 0 as well.  According to the schematic they should match pin 14 and 15 on the FV-1 and there is nothing between the FV-1 pins 14 and 15 and eprom pins 5 and 6.  Checked for continuity between 15 and 5 and between 14 and 6 and it reads good.  Where did the voltage go?

One additional note.  The volume of the popping when changing patches is controllable via the wet pot (the wet pot seems to be working but no effects.)

update:  tracing the signal and found it dropping out at R4.  R4 reads 10k.  Not sure why signal is lost there.  it's on one side but not on the other.

with the tails switch on the signal is present at pin 1 and 2 of the FV-1 but not on 28 or 27.  It's not coming out of the FV-1.

I'm considering the headtrip 2 but it isn't clear to me how the patches get loaded on to the IC?  How does that work?
General Questions / Stutr can the depth be less???

I built the stutr and like it with one exception.  With the depth turned all the way down (counter clockwise) it is still a bit "too deep".  In other words, the affect is quite pronounced even at the lowest depth setting.  The depth control works fine I just wish that you could have the affect turned nearly off or have a very subtle (more subtle depth) trem.  Any suggestion on what i could change to give me a bit less depth at the lowest setting?
