Best Bass Direct Boxes – Through the Wire

Through the Wire - Your guide to the best bass direct boxes

In the music world, the means of how sound is transferred is essential for a live or recorded performance to be a success. The sound engineer must assure that all the signals being sent by the musician is received on their end at the desired quality. In the bassist’s end, you wouldn’t want your carefully tailored tone sounding crappy going out from the PA system. To achieve this goal, the use of direct boxes are utilized. But of course, with the quest for tonal excellence being subjective, what are the things to consider in getting the direct box that would best suit your taste?

Instrument type: This is in direct reference to the type of instrument you are going to use with the direct box. Are you planning to use it on an acoustic guitar with an active preamp, or are you planning to hook your bass guitar directly into the house mix?

Input: How many instruments are you planning on using with that direct box? Of course it is ideal that a ratio only one instrument per direct box should be utilized, but there are a number of direct boxes out there that could deliver the job just as good with half the price.

Tone quality: Of course clean tone transfer is ideal in any signal chain, but there are a few direct boxes out there that add just a bit of “flavour” to spice up your low end groove.

With these things to ponder on, here are our recommendations on the best bass direct boxes.
