A cut is also needed to prevent the capacitor connecting to the 470k resistor. cctsimhttps://www.blogger.com/profile/02534096833285088736noreply@blogger.comtag:blogger.com,1999:blog-6847048658257278783.post-7261242389981178252018-08-27T15:23:07.355+01:002018-08-27T15:23:07.355+01:00PS.

And found it great on clean.<br />Just a little bit noisy but it's how ross compressor work.<br /><br />This compressor fix my problem on wahwah (thomas organ cry baby wah).

I read in the Dyna Comp build that the trimpot is for adjusting the input level for noise.<br /><br />What should the trimpot initially be set to, 2k or some other value? Has anyone found an acceptable range for an initial setting?<br /><br />Thanks you.Anonymoushttps://www.blogger.com/profile/03341697050662850586noreply@blogger.comtag:blogger.com,1999:blog-6847048658257278783.post-39204464326804137162015-10-31T14:31:03.759+00:002015-10-31T14:31:03.759+00:00HI guys .

I think i have Mr. Squishy clone for sale :)<br /><br />They have some minor differences soundwise, but generally i'm leaning more and more to Dyna, as it sounds (in my opinion) a bit more simpler. Both are just great. Fat and round, just like good compressor should be.<br /><br />I'm seriously considering about boxing these two in the same box: "The latest attraction from Motown! - Dyna & Ross" :D<br /><br />Great builds both of them. Definitely a keepers.<br /><br />Thanks a ton!<br />+mmirosolhttps://www.blogger.com/profile/02400327798106357876noreply@blogger.com
