Top Bass Guitar DI Features To Consider
- Clean Signal – The clarity of the signal produced by your DI box will effect every aspect of how you use it in the future. The last thing you want is to break out your new DI box and find that your new pedal puts off a gnarly hum of some sort. And for an audio engineer, nothing is more annoying and disappointing. Clean sound is important for live sound, but recording your guitar tracks with a quality bass DI is even more important. Simply put, any DI box for your bass that introduces interference into the signal chain should be rejected and replaced.
- Transparency – One of the most important features in bass DI boxes is transparent sound transmission. Transparency in a DI box means the preamps and electronics won’t color your instrument’s natural sound when you don’t want it to. Of course, sometimes you want the coloring effects of the preamp DI, and some DI boxes are known for having desirable coloring effects on your bass. But the overall versatility of any give bass DI will depend on it’s ability to offer transparency.
- Rugged Quality – Performing on stage and touring is not the easy life for music gear. Pedals and DI boxes are stepped on by accident, moved around a lot, and sometimes not very gently. A bargain basement DI box isn’t going to be made for life on the road, and won’t withstand the abuse for the long haul. Tough housing and internal electronics are not tremendously difficult to find, but it will require selecting proven desings that have been time-tested on the road.
- Versatility – The best DI pedals for bass guitar offer a variety of uses, inputs, outputs, and generally beneficial features that make them useful for the common needs of musicians. Whether you need a balanced output, a little gain or overdrive, or maybe just save some cash on an expensive amplifier, a quality DI pedal can get you where you want to go.
