J 48 : Radial at its best.

After using many different DI boxes over the years I can say this one is the best so far. It sounds amazing on accoustic guitar and double bass. You can't go wrong with this one if combined with a high quality pickup. When I use J48 I usually do not need to wrestle with EQ to get the right sound, just low cut and some slight details on EQ and it sounds amazing. The DI is very sensitive so you may need to use the input pad switch more often than you would on other DI boxes otherwise your sound may get distorted. I use this DI box for 2 years now for live sound applications and it never let me down. If you prefer to use this DI for bass guitar (especially with active bass pickups) you may want to consider JDI instead because it can handle much higher inputs without distortion.
