This Harley Benton DI-Expander is a seriously impressive value. It's a great all-in-one solution for gigging bassists needing a clean DI signal, a bit of compression, and some EQ shaping – especially for players on a budget who want a professional-sounding rig. The balanced DI output is a real bonus for recording or live sound reinforcement.
