I recently installed a Keystone bridge pickup in a custom Tele with a 4-way switch. The rhythm pickup is a P90. I did the most thorough shielding job I could do, and have been amazed by how quiet this guitar is. I'd been prepared for a real buzzer. My reference is an unshielded Srat, which picks up radio signals from deep space. I'm thinking I should put some more of these Keystones away before Becky and Bill start charging as much as they easily could.
