The other day Max Valentino contacted me off list with a similar problem, when using his dl4. At first I thought it might be the hi frequency distortion common to most piezo pickups being amplified, but now I'm not so sure. I have noticed it with my two DL4's on occasion particularly when looping with my acoustic electric guitar and resampling on to a repeater or jammman, but never to the degree that you mention. perhaps the problem as Nic suggested is related to something near you radiating EMF's or maybe a poorly shielded power supply. I've only noticed the sound you speak of when playing in my studio with a computer screen, large mainframe computer, and racks of signal processing gear. I do know that those wall warts are notoriously prone to picking up line noise, if care is not taken to separate them physically from line or power cables. On my main pedal board, I use a Voodoo labs pedal power to power all of my stomp boxes, including a DL-4, and have not really noticed this problem. However, recording at half speed on the DL-4 will give you a greatly reduced sampling rate, and potentially more sonic artifacts.

The other day I noticed that my Line6 DL-4 now includes an unpleasant buzz/hum/whine when recording in half-speed mode. Switching back to regular speed just shifts it up an octave, although recording and playing back at full-speed have no problems. So, I pulled out my spare (neither one has seen much use recently) and found that it had the same problem, although to a lesser degree. Both units are about three years old and have seen only light usage and been stored on a pedalboard or somewhere safe, and I've tried different guitars, amps, cable, etc. I know they didn't used to do this--has anyone else seen this problem?
