Did you get a pseudo-C&D letter from Gibson's attorneys that is suitable for framing?

Thanks Brian. 

any chance you will start carrying the new designs for the VFE pedals?

Thanks for the updates and best wishes on having a happy holiday with your family.

thanks again, and for the quick replies today.

I cut out the 100K resistors and replaced each one with a 1M trimpot.  By maxing out the resistance I could get the voltage down to between 13 and 14 volts for each test point.   I was surprised it would not drop the voltage more than that, but that still made a big difference in the sound.  With those lower voltages the distortion in the tone and adjustment with the drive pot is great.  Before it was a pretty clean signal that could be overdriven with a boosted input, and now there is some nice dial-in distortion without upping the level of the input. 

thanks.

I built a working Uber Tuber from the original version when it was released.  It has a warm clean sound with very little distortion unless the incoming signal is high.    I noticed today there had been a 1.1 revision to the build doc not long after it was released, and saw that two trimmers were put in to replace the 100K resistors for the plate voltage.  The build doc suggests setting the trimmers to bias at about 12 volts, but there are comments that most of the tubes work OK over a bit wider range.

I checked the plate voltage on my board and they are both running over 17 volts using the 18 volt Dunlop power supply.   Would changing the resistors to drop the voltage to 12 change the sound from the tube to possibly add more use to the drive/cut/sat controls?  If not, is there a reason not to leave the board as-is with the higher plate voltage?

one quick tip to share I learned recently -- best way to open a through hole on a board is heating the solder and then putting a toothpick into the hole and let it cool.

I was wondering if it was going to be a fuzz face variant.  thnaks!

Looking forward to the HT2.  Is the Vionenzz Fuzz a take on a classic pedal?

I built the Glasshole first because I was waiting for the taptempo chip to arrive.  Got the chip and built the Wavelord.  Both pedals are very nice on their own, and really interesting to link together.  A great combination.

Hope you can rewind and unlax, or something like that! 

checking your zener sounds like a good idea.  something is dropping your voltage in that part of the circuit.   what voltage reading are you getting at d5 & c11?

Glad to see the new stuff go live.  Nice demo on FB as well.  Order placed.
Thanks again for all the effort you put into the designs and build documents!  And I hope this means that you are feeling a lot better.
