feeback problems!

I play an indian classical instrument with several live groups. The problem is that I often run into feedback once i get on stage.

I am basically using a transducer type pickup fit near the bridge of my instrument but set on to the goat skin (which the bridge sits on).

Once I start amping up the volume, then I start getting feedback. The other issue is that when I'm playing live, my pickups seem to be picking up other sounds like the drums.

What are some ways I can try to get the feedback in check?

Thanks!

    Behringer makes a couple of products using what they label as "feedback destroyer" technology.;
    www.behringer.com/DSP1124P/
    www.behringer.com/DSP110/
    I know someone who had what sounds like a very similar problem with live sound (using a different type of instrument), and the DSP110 works well for him in this way.

    Behringer gets a really bad rap for their gear, and often deservedly so, but some of it turns out to be pretty good, and the price is always low. If there's a way you can rent one of these or get a returnable unit just to experiment, it's worth a shot. I don't know if there are comparable types of products like this made by anyone else, so that may be another thing to look into.

    Note: this is just a "dirty fix" type of suggestion. If there's a way to actually prevent the feedback in the first place, perhaps by changing how you amplify the instrument, that would be ideal :) What kind of instrument is it specifically?

      well .... I have had nothing but trouble with behringer gear. currently I'm using one of their midi controllers and it sucks really bad, it's super glitchy and has all these electronic noises if you press buttons such as pitch bend( pretty much right out of the box) it also sends wrong midi messages and so I'll pull down the left fader on the device and it pulls down the right fader on tracktor... my friend bought one of their pioneer djm600 ripoff mixers and it broke after 3 days. piece of shit company .... look for something better.

          Using a transducer on a snakeskin would just turn the instrument into a giant microphone, which would pick up the other acoustic instruments and feed back with it's resonating frequency.
          I would agree with Rob. The way to go is with a tiny mic aimed at the resonating chamber but not attached to it. This will also give a sound that is closer to the acoustic sound of the instrument. (unless you typically press your eardrum onto the instrument :)

          You could then experiment with aiming it at the strings or the snakeskin.

        Some of their gear does suck - no doubt about that. But the Behringer gear I do own (a small mixer and a headphone amp) has worked reliably for years, and my friend's DSP110 units have also worked well even enduring lots of road/air travel, etc. So while I'm not saying this is the greatest piece of gear nor necessarily the answer to the problem, I wouldn't dismiss it just because of the brand name.

          thanks for everyone's feedback (ha!, sorry for the awful pun).

          Anyways, we happen to have an extra feedback destroyer in our studio (we have a lot of stuff laying around).

          So i'm gonna give a try.

          thanks again!
