It was a headache until I noticed what was going on (first perfboard build). I just rotated 180º and it's fine, but bothers me aesthetically that pots are so low in the enclosure and close to the switch. The other option is to build it as usual but all the pots would work in the oposite direction (volume decreases clockwise). Thanks for the layout anyway :)Julen I.https://www.blogger.com/profile/05375642891538470510noreply@blogger.comtag:blogger.com,1999:blog-5481402030233340127.post-3952868951063680512023-03-27T23:55:39.163-04:002023-03-27T23:55:39.163-04:00I built this one, it works pretty fine but the Tri...I built this one, it works pretty fine but the Trim pot does not work that lineal, at the last 4th of the pot it is noticeable the change in gain, the other 3/4 of the pot barely does anything, is this normal?

It sounds good enough that I'm confident in starting to put it in perf board, with a socket of course.Ben Van Sicklehttps://www.blogger.com/profile/18394995756814328104noreply@blogger.comtag:blogger.com,1999:blog-5481402030233340127.post-83363876804738575832019-08-05T04:18:18.340-04:002019-08-05T04:18:18.340-04:00Hi, Would you be able to use a TL072 here , or wou...Hi, Would you be able to use a TL072 here , or would the LM4558 equivalent nte778A be more suitable<br /> Graingerhttps://www.blogger.com/profile/09326880596866145907noreply@blogger.comtag:blogger.com,1999:blog-5481402030233340127.post-9614127458083240092017-08-01T09:05:08.161-04:002017-08-01T09:05:08.161-04:00I was mistaken, all the pots work, except gain.
