Title: Dirtbag feedback control
Post by: gitaar0 on October 31, 2012, 01:37:36 PM
The feedback control on my dirtbag works mainly from 12:00 to 3:00.
Before 12:00 it is basily one repeat and after 3:00/4:00 it goes into oscillation.
Is there any way to spread this out more evenly across the whole pot range?

The rest of the dirtbag (mn3005s) works really well.

Thanks
Marc

Yes, use a larger value for the pot. My preference there is 100k. 50k is probably enough, too.

I will try that.

Tweaking the gain trims can help with this too, I had the same thing.

I wonder if a reverse audio taper might help...

Replaced it with a 100k pot and yes, that works really well.
Thanks for the tip brian.
