Anyway, is a 10 minutes build, so worth a try, and man...<br /><br />Is not a tonebender, far away from a germanium or even silicon MKII - III, but it sounds nice to my ears. More on overdrive than a fuzz, but sounds really fine for a so little circuit. Surely it will get boxed (1590A, of course).<br /><br />The only issue is that the fuzz knob has to be definetely antilog, even with a lin the fuzz is on the last 20% of the sweep.<br /><br />Give it a try!JaviCAPhttps://www.blogger.com/profile/15831602988871935058noreply@blogger.comtag:blogger.com,1999:blog-6847048658257278783.post-65590620920613948742013-09-29T17:51:19.584+01:002013-09-29T17:51:19.584+01:00Complete redraw.

All Tonebenders are quieter than expected by default.<br /><br />You could try smaller pot for fuzz, like 10K. And you could try upping the 100K resistor in parallel to clipping diodes to get more gain.<br />+mmirosolhttps://www.blogger.com/profile/02400327798106357876noreply@blogger.comtag:blogger.com,1999:blog-6847048658257278783.post-85001825288402627492013-09-29T16:15:42.652+01:002013-09-29T16:15:42.652+01:00I actually took out D1 and placed a jumper in its ...I actually took out D1 and placed a jumper in its spot which kind of fixed the issues I was having.

Its probably worth mentioning (for the newbies out there) that if D1 is omitted then a bridge will be required otherwise no voltage will get through, thanksOtalgia FXhttps://www.blogger.com/profile/14151376882555213024noreply@blogger.com
