I have lurked around here for some time doing research but never posted. You guys are a great resource! I have a new Wolf build that is 99% complete. I used Mike Walds Wolf 3.0 wiring schematic. The problem is that the volume when the OBEL is engaged is MUCH louder than when it's disengaged. In fact the volume seems to go from minimal to full between 0 ans 2 on the volume pot. What is a 1 on the OBEL is an 8 when the OBEL is switched off. The confusing part is that if I turn off the individual effects in the effects loop but leave the OBEL engaged, the volume is exactly te same as when I turn the obel off (as it should). I have ruled out the effects themselves. I have tried my delay, qtron, distortion with the same results. I have tried them direct from the guitar output and the volume when the effects are on and off is roughly the same. I had a guy who knows about electronics etc check my work and after an hour of looking we couldn't find a problem.
I tested the Alembic blaster and it is indeed working with and without the OBEL engaged. When I adjust the gain on the blaster it does increase/decrease as it's supposed to for both the OBEL on/off. It doesn't however have an effect on the difference between the two.
What really baffles me is that the volume is consistent with the OBEL engaged or disengaged providing the effects in the loop are off. What is causing the increase in volume from the effects?????
Mike wald has been very helpful but I'm willing to look for any insight as to where I should look next. Could it be a ground issue or could a bad OBEL cable (from Lieber Guitars). I'd post a picture but the "board attachment quota has been reached"
Also thanks to Leo at Scarlet Fire Guitars and Robert at Rusch Guitars as well as Mike Wald for their help with parts and advice on this project.

Anthony, I think I've recently done the same thing by mistake You've probably hooked it up so that the main volume's taper is reversed... Anyway, my symptoms were very similar...
On the main volume pot, looking down at in from the back, as it's installed in the guitar, the right lug should be the ground, the middle should go to the output jack, and the left is the input to the volume.
I just rewired that way and I think that was a big help. I've tried so many things it's all becoming a blur at this point what's made the biggest difference. Is it possible there's a difference in the lugs on ALPHA vs CTS pots? Either way it seems there's a much more consistent volume control now. I wish I understood the science behind more of this. Learning as I go!
Not sure if was the same issue as MB's, this issue only presented the volume difference when an effect was engaged. With the OBEL bypassed it worked normally. MB, your issue was on both sides of the switch. I guess it is possible they were similar issues, but i don't think they were identical. That all said, i am just happy both of you guys got your axes working!
"Tone is in the instruments. Technique in the hands. Do what you will." ~quote from some guy at the TGP forum
"Without a doubt, the quality of your instrument will effect your tone, and any pickups, effects, amps, and microphones used along the way will also have an impact on the sound waves."~Cameron Mizell
That was my first thought but none had any serious impact on the volume when ran direct from the guitars output. I wish I knew exactly what I corrected but after some re-soldering and minor changes it seems like it may be correct now. Need to give my brain a rest before I investigate any further!
