Hello, I recently bought an EBS Octabass pedal. It's fine pedal and does the job, but when in bypass, a background hum/hiss appears. I took it out the chain and plugged it in seperately, but it kept on humming when in bypass. Here are a few clips of the problem (fretless, open G-string) Here's the clean signal (bass -> computer) http://www.mediafire.com/?3oj5zmuj10d And here's the problem (bass -> octabass -> computer) http://www.mediafire.com/?aet0hf0mlpd Any ideas? Should I sell the pedal or buy an NS-2? Thanks!
