I have it hooked up after a Colorsound 1 knob fuzz I built (going for a two knob vol/tone type setup) but I can't seem to get it anywhere near unity volume without an awful feedback. The 1KF circuit is essentially the DAM Meathead with a few value changes (and a trimmer instead of a bias resistor) that worked no problem before I added the tone circuit. I have the trimmer on the boost section as low as I can and still have signal from the fuzz pass through and it still feeds back BAD. I'm about ready to just ditch the layout and go for something else (maybe a mkiv bender with an internal fuzz trimmer?) but at the same time, I'm too stubborn to know when to quit. I appreciate any insight!emilyhttps://www.blogger.com/profile/10458542414416002370noreply@blogger.comtag:blogger.com,1999:blog-6847048658257278783.post-38358385479467809342021-07-28T12:31:09.253+01:002021-07-28T12:31:09.253+01:00this project is great was thinking to do this for ...this project is great was thinking to do this for a while, <br />if i want to make it as stand alone pedal, <br />Do i have to ad a coupling capacitor( for example 0.1uF) and a resistor as a high pass filter (43k i took those value from the lpb1 circuit analysus from Coda effects website) Red capaccihttps://www.blogger.com/profile/04120762540712073332noreply@blogger.comtag:blogger.com,1999:blog-6847048658257278783.post-77810700940016061132021-05-13T17:54:34.461+01:002021-05-13T17:54:34.461+01:00Hi,what is Zsrc (in the tonestack calculator)?wher...Hi,what is Zsrc (in the tonestack calculator)?where is on the board?<br />thanksbrujohttps://www.blogger.com/profile/05958421594444444043noreply@blogger.comtag:blogger.com,1999:blog-6847048658257278783.post-82562281294789335682017-04-18T11:49:10.948+01:002017-04-18T11:49:10.948+01:00just used it with a modified jfet vulcan od with j...just used it with a modified jfet vulcan od with j202's and some added gain and voltage. sounds so much better with this thank you!Anonymoushttps://www.blogger.com/profile/17650462389842308339noreply@blogger.comtag:blogger.com,1999:blog-6847048658257278783.post-13402298321370060392017-04-13T15:25:22.022+01:002017-04-13T15:25:22.022+01:00make the 39k resistor a 50k pot, and that will wor...make the 39k resistor a 50k pot, and that will work as a treble cut. make the 22k resistor to ground a 50-100k pot and that will let you cut and boost the midrange. the original pot will still pan around the circuit.<br />or look at the colorsound overdriver and compare it's tone stack to the big muffs for some clues how to do it. you'll see they are pretty similar. the same resistor in that cct going to ground can be swapped out for a pot to make a midrange control there as well.pinksterhttps://www.blogger.com/profile/13385798043782856976noreply@blogger.comtag:blogger.com,1999:blog-6847048658257278783.post-77431864694353854052017-04-13T15:15:59.982+01:002017-04-13T15:15:59.982+01:00don't forget to make the add on pnp... flip th...don't forget to make the add on pnp... flip the power rails and use a pnp you'll be finepinksterhttps://www.blogger.com/profile/13385798043782856976noreply@blogger.comtag:blogger.com,1999:blog-6847048658257278783.post-21881596851500779122016-11-28T20:17:08.812+00:002016-11-28T20:17:08.812+00:00Put this on a Dod250.. so good.

My procorat layout works fine but I'd like more control over the tone. Would I just daisy chain the 9v going into the Rat circuit (split the cable to the BMP circuit before the Rat)? And where would it be best to ground the tonestack circuit to?
