The passive Palmer PAN 01 is a really great DI-Box for its price point. I use it primarily for recording and practicing guitar and bass at home. I bought it in the first place due to the limited headroom of my interface, the Focusrite Saffire Pro 24.
After a little time I also did some reamping which worked absolutely flawless.
Since the PAN 01 is a passive DI-Box, it reduces the signal's level when the impedance is being transformed. If the gain is way too high the -30dB switch helps reducing it to a proper level.
The original signal does not seem to be coloured, which might be the most important thing for most users.
On the upsides it also comes with an ground lift switch, it is well built and it comes with a 5 year warranty.
