I chose the Samson MDA1 Pro DI box to ensure I could plug my passive-pickup electric guitar directly into the line-level inputs of my MPC Live, to use as a multi-effects processor and amp sim. Instantly, it made a huge difference, giving high gain and low impedance as required by the line inputs, and improving the overall tonality of my guitar sound. Would buy again.
Build quality is sturdy and feel is great. Audio quality is good as well.
