I bought the Palmer PAN 01 to install it in my home studio. I have been using it, to plug in my guitar, run it straight in my interface via the XLR-Output and connect my amplifier to the link out. Featuring a -30db- and a groundlift-switch, it delivers everything you expect from a passive DI-Box and it worked fine. Just one of those little pieces of gear, you do not hear, but make your life a bit easier. Then, after two years of usage, the inputjack broke, so i had to change it. Remember, that i did not use it for heavy gigging or something like this, just to plug my guitar in, while sitting next to it. So i cannot give more than two stars for the quality.
