The volume on my built drops considerably, as if it had a "pad" on it. Is it due to the TL072 or should i remove R9 or put a smaller resistor (like 200r or 560r)? Thanks for the info, have a good day.Ipirangahttps://www.blogger.com/profile/03628870985815368632noreply@blogger.comtag:blogger.com,1999:blog-3033460626772757790.post-75762678491866982062017-09-27T18:18:38.340+01:002017-09-27T18:18:38.340+01:00please layout pcbplease layout pcbAnonymoushttps://www.blogger.com/profile/18290220320535918116noreply@blogger.comtag:blogger.com,1999:blog-3033460626772757790.post-32958919480142327662015-11-14T20:36:05.286+00:002015-11-14T20:36:05.286+00:00I'm wondering about adding a balanced -XLR out...I'm wondering about adding a balanced -XLR output.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-3033460626772757790.post-72557915644712343222014-05-14T04:49:14.612+01:002014-05-14T04:49:14.612+01:00Very cool thank you!

Do you think it would be easy to and a boost/cut ability at the selected frequency? Do you know which components control the boost at the frequency?Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-3033460626772757790.post-33673992094886151272013-12-10T12:17:27.974+00:002013-12-10T12:17:27.974+00:00that's cool dude - you'll have to send me ...that's cool dude - you'll have to send me a picture. it is an amazing little box. <br />good call on the low batt indicator though with this box it doesn't draw much current the TL062 itself only draws about 500uA so batteries last ages in itDrStevensonhttps://www.blogger.com/profile/13901235832359203061noreply@blogger.comtag:blogger.com,1999:blog-3033460626772757790.post-33196802765000204752013-12-10T02:42:22.729+00:002013-12-10T02:42:22.729+00:00Excellent project!

At first, I didn't think it was working since there was little difference between the three switch positions. Then I rolled back the frequency knob and all I can say is WOW! I love the ability to easily switch between a very subtle sound, a bright in-your-face sound and a rolling bassy sound with just a quick flip of the switch. I combined this circuit with your low battery indicator so I could use it in a performance without worrying about whether the battery was dying. Thanks very much for putting this project together.

I also Punched an XLR hole on the side and added a LL1935 transformer inside.<br /><br />Worked out nicely.Alaryhttp://www.alary.comnoreply@blogger.com
