Xotic Tri-logic


Sold out.

 Unlike many pre-amp units on the market today, which tend to have that peculiar "Active" sound, the Tri-logic Bass Pre-amp features a greatly expanded, wide dynamic range, for a natural warm sound, sought after by many of today's players. Also, the unique characteristics of various bass has been restored, and has been realized with a very low-noise output.

All hand wired and made in the USA.

Designed and tested with feedback from professional musicians.

You can make a sound to match any musical style. It works great with natural sound when used with acoustic bass with pickup.
