Agree with Croustanoune in that this doesn't sound like the typical Vox AC30 overdrive/distortion pedal - if you back-off the headroom control (which, to me, is wired backwards - full CW is max clipping and I would think that a "real" headroom control would act just the opposite), you still get a rich, sweet collection of harmonics that ring-out on certain notes and with an edgy pick attack. I recommend a 10KC (reverse log) for the headroom control as I found most of the useful settings are in that last 1k of resistance.

It sounds like playing two different amplifiers at the same time because of the diodes sounding so different from one another. I would not say that it sounds like an old vox per se, but I sound very interesting on it's own. I would personnaly rename the headroom control ''blend'' as it blatantly blend one diode into the other. I would also rename the volume control ''gain'' and the master control ''volume''. The volume controls act much like a non-master volume amplifier (as you turn the volume up, it starts to break up into overdrive) hence the name ''gain''.Croustanounehttps://www.blogger.com/profile/16861922345098497812noreply@blogger.comtag:blogger.com,1999:blog-5481402030233340127.post-38093014199419842132017-09-08T06:02:17.764-04:002017-09-08T06:02:17.764-04:00I have done this circuit for some time, but I forg...I have done this circuit for some time, but I forgot to mention something that I found very special, the combination of these clipping diodes, give a very musical and dynamic touch, that I had never heard anything like it, the SB340 is exactly the same thing than the 1N5822, much more common and easy to arrange, but huge. I already got some smd to replace. The transistor at the time, I remember that it was not easy to find, I bought only ten because they were expensive, but in the end, I ended up with some other one because I did not notice much difference.<br />But only by the combination of the diodes is it worth to test this circuit!Monjehttps://www.blogger.com/profile/03657786094910154709noreply@blogger.comtag:blogger.com,1999:blog-5481402030233340127.post-13242268063401273172016-09-20T13:20:31.835-04:002016-09-20T13:20:31.835-04:00Hi, i have built and it works, but i dont understa...Hi, i have built and it works, but i dont understand what is the meaning of headroom, because i turn it up has no different.

I used sb360 instead. Everything works fine, but as i increase the headroom pot, i have more overdrive but the volume gets really really low.. Could it be the sb360, can i use BAT46 instead? Or is it something else? Thanksstghttps://www.blogger.com/profile/12971041643439983315noreply@blogger.com
