Not concerned about the volume drop -- this looks very similar to what's happening in a Gibson-style 50's wiring tone stack? If the vol drop is an issue I'll just leave the pot wide open and forget it's there :)<br /><br />So just to make sure I understand (I am a novice, this is like my 3rd circuit build): vol 3 wire on the board goes to tone 1, tone 2 gets a 22nF cap with the other end connected to the ground lug of the output jack, and tone 3 connects to vol 3? <br /><br />Huge thanks again for your help.WOOLhttps://www.blogger.com/profile/09898765875604208864noreply@blogger.comtag:blogger.com,1999:blog-6847048658257278783.post-18721888729227220872021-03-07T15:14:58.985+00:002021-03-07T15:14:58.985+00:00Actually thinking about it, go with the second one...Actually thinking about it, go with the second one on that link. Then you don't have to bother with the ground connection and just solder the cap between Tone 2 and 3. Added advantage being that you don't get any losses.IvIarkhttps://www.blogger.com/profile/08416945174853142251noreply@blogger.comtag:blogger.com,1999:blog-6847048658257278783.post-43818320881252652512021-03-07T15:12:24.279+00:002021-03-07T15:12:24.279+00:00The easiest way would be the top option of the Stu...The easiest way would be the top option of the Stupidly Wonderful Tone Control here:<br /><br />http://www.muzique.com/lab/swtc.htm<br /><br />The Volume 3 wire shown on the board will then go to Tone 1, Tone 2 would connect to a capacitor with the other side going to ground and Tone 3 would then be the new Volume 3 connection.<br /><br />Use a 100K linear for the tone pot and experiment with the cap value, 22nF will be a good starting point. If you want more high end lower it, if you want more bass increase it.<br /><br />The only caveat with this type of tone control is that you will lose some level, so only do it if you have plenty of volume on tap that won't cause you problems.IvIarkhttps://www.blogger.com/profile/08416945174853142251noreply@blogger.comtag:blogger.com,1999:blog-6847048658257278783.post-28906010422006616042021-03-04T14:04:35.369+00:002021-03-04T14:04:35.369+00:00Would it be possible to add a tone knob to this?

I built this and I really like it, much more than the silicon version.<br />Coupled it with the 7660s voltage inverter from this site to allow daisy chaining.<br />After some tweaking I boxed it with a MP16B (hfe ~ 65) and AC125 (hfe ~ 70) for Q2 and Q1 respectively. Used a B10K sundial (great suggestion) and replaced 2k2 with 3k3 and 33k with 39k for biasind (I get 0.6V in Q1collector and a fair amount of range around 4.5V in Q2collector). <br />Thanks for the layout!WTFiCanBuildMyOwnPedalshttps://www.blogger.com/profile/18299472707281011635noreply@blogger.comtag:blogger.com,1999:blog-6847048658257278783.post-18313028547377153022019-07-17T14:52:37.252+01:002019-07-17T14:52:37.252+01:006 years later and this comment saved my build - bi...6 years later and this comment saved my build - biasing q1 to ~1.4v just brought this baby to life.
