I was recently blessed to acquire an Essential Sound Products(ESP) MusicCord and an Xotic Bass RC Booster. Here is my review and comments on these AMAZING PRODUCTS. First, an edited version of an email that I sent to Michael Griffin of ESP. In all honesty, despite the very sound science and engineering behind the ESP cords, I was skeptical about really detecting any actual audible difference. There is good news and bad news. The good news is THE CLAIMS HAVE BEEN EMPIRICALLY DEMONSTRATED TO MY EARS!!!!!!!!!! The bad news is I AM HOOKED ON THE CORD!!!!!!!!!!! Here is a brief description of my experiments and real world use. The day that my MusicCord arrived, I opened the box and was blown away-and that was just with the bag-VERY NICE TOUCH!!! The cord is what I expected -BIG! I plugged in my SWR Workingman's 10 combo bass amp using the stock power cord and played my Ken Smith Black Tiger 5 for a few minutes. I then switched to the MusicCord and powered my amp back on and played without making any adjustments on my bass or amp. HMMMMMMMMMMMMMMM.........something is different about the sound. I was initially disappointed with the MusicCord because there was what I thought was a lack of bass response. I repeated the experiment again, this time recording the results using my Zoom H4 recorder. After doing repeated A/B listening of the recording, I figured out what was happening. There was not a lack of bass response as a result of using the MusicCord-THE BASS WAS TIGHTER AND MORE DEFINED!!!! NOT ONLY THAT, THERE WAS MORE OVERALL CLARITY THAT I DID NOT EVEN REALIZE I WAS MISSING!!!!! Cool!!! Now, onto the real world test-playing in church on Sunday with the choir and band, including the dreaded Leslie organ speaker cabinet just a few feet away from my amp setup. My set up consists of a Euphonic Audio Micro 300 amp, a Schroeder Mini 10 +L bass cabinet and a Furman power conditioner. During the first service, I replaced the stock power cord with the MusicCord. I have never really had any problems hearing myself and everything sounded good-REAL GOOD!!! Between the first and second service, I unplugged the MusicCord, plugged the stock cord back in and played a few notes. I COULD NOT UNPLUG THE STOCK CORD AND REPLACE IT WITH THE MUSICCORD FAST ENOUGH!!!!!! Even with the clarity of my setup, the MusicCord removed a veil that I did not know existed!!!!!! After second service while packing up my gear, one of the choir singers, who is also on the pastoral staff, approached me. He mentioned that normally here can here my bass along with the organ (which is way to loud by most accounts!). This time, even though he was behind me, he could hear my bass just like he was right in front of me!!!! In summation, the MusicCord has passed the test, Michael!!!!!! I am a firm believer in your products and will tell as many people as I can about the MusicCord. Now, the Xotic Bass RC Booster. To make a long story short-THIS THING IS THE BOMB!!!!!!! What it does is make your bass sound BIGGER without adding or subtracting to the sound-CLEANLY!!! Here is a great demonstration by Melvin Lee Davis: http://www.prosoundcommunications.com/english/video/melvin_davis/index.html So, if you are satisfied with your current set up and would like to improve the clarity and impact of your sound, you owe it to yourself to check out these products.
