"Hey! This is NOT for guitar pedals."
Overall: Ok, I think the first guy to used this didn't actually know what this is for. This is NOT meant for guitar effect pedals. Your single coil guitar pickup is going to buzz, this won't fix that. This unit works best in between your mixer and power amplifier. OR, in between rack mount effects/processors. That is where it is meant to be. For all other problems, there are other solutions. For your guitar, research copper shielding your guitar. Or perhaps switch out the single coil pickups. Your guitar effect pedals, try getting a "zero hum" AC adaptor. Danelectro makes an awesome one that works with all my pedals. And it pretty much goes without saying get some quality cables. The shorter the cable run, the better. I'm not saying buy Monster Cables, or Mogami cables... But it wouldn't hurt to try a quality cable. What I'm saying is the guy who wrote the review "useless for guitar effects loop" is right. This is useless for a guitar effects loop, and he should have known that before spending $60 on a product he didn't understand the use for. But thats just me, I might be wrong.

"Useless item for guitar effects loop."
Sound: Sucks tone from the guitar, reduces signal strength & adds it's own noise. I use EMG active pickups, so I don't know if that has anything to do with it, but I got the unit to remove buzz & hum from ground loops, not to add it's own. Feature: Two channels Ease of Use: Plug it in - doesn't get any easier Quality: Seems OK Overall: It get a 3 because it actually makes signals sound worse not better.

1. zZounds offers the industry‘s most musician-friendly payment plans

zZounds offers a variety of Play as You Pay installment plans that allow you to get the gear you want today. While our competitors might offer house credit cards that require you to fill out an application and pass a credit check, our payment plans are easy to get, simple to use, and, best of all, accrue zero interest. Unlike those house credit cards that can leave you vulnerable to exorbitant interest charges once the promotional period ends, we never have and never will charge interest when you take advantage of one of the zZounds Play as You Pay plans.
