how to build a feedbacker? (like old df-1 boss pedal)

To cite my favourite Shakespeare quote of all: "Nay, I would not knowest mine own wit lest I break my shin upon it." :wink:

Is this a dagger I see before me, or art thou just pleased to see me?

Ansil's idea will probably produce a lot of squealing, but not the kind of "guitar feedback" it seems like you want. As R.G. mentioned, you have to get the mechanical string vibration in the loop too. In one of Aron's previous forums, someone was working on a device that used a small speaker that connected to the guitar headstock and induced mechanical feedback and sustain at low volume levels. From what I remember the soundclips were pretty impressive. That ends up being more of a wiring and "human factors" kind of challenge than an electronic one, but it seems like it is certainly doable.

the whole idea is that you are already standing in front of a mildly cranked up amp that needs a push, to get it into feedback.. similar to the above post.  there
