mikevirok Posted April 23, 2010 Report Share Posted April 23, 2010 Hey all; it's been a while since I've stopped by this forum. I've been really busy with my repairs business and haven't had much time for recreational luthierie in a while. But I'm back!!! Here's my dilemma. I recently purchased an Artec VR2 on-board guitar preamp (it's a variable boost that's not over-the-top). Well, before I install it into a custom build that I'm about to begin, I built a small project box to test it out... When I engage the boost (no guitar hooked up to the cable leading in) and turn the boost up, I begin to hear it pickup AM radio transmissions (think Spinal Tap folks, it's the same issue)... I need to make this stop before I begin the routing job for its installation. If I can't make it act only as a boost and not pickup the radio frequencies, then I can't use it for this project. Now I currently suspect the cause for this is a lack of shielding from outside frequencies. It's mounted in an old Seymour Duncan pickup box for testing purposes only. So, could a good copper-foil shield keep out the frequencies? Virok Quote Link to comment Share on other sites More sharing options...
