The OD’s drag control and PZB booster provides a variety of resistance levels which make it work well with whatever kind of bass you could imagine using with this preamp, including vintage instruments, acoustics, and other low-output axes. An 1/8 inch headphone amp has its own dedicated volume control, so you can still be in practice mode and sound great. The Bassbone OD has won over some of the premier bassists working in the industry today, including Rhonda Smith (Prince, Beyonce), Carlos Puerto (Chick Corea, Herbie Hancock), and Justin Meldal-Johnsen (Nine Inch Nails, Beck).

            Ampeg’s SCR-DI bass preamp pedal provides a quick and easy way to dial in the refined bass guitar sound that bassists have looked to the company for over the last few decades. Like all preamps, this unit has EQ and tone controls that allow you to fine-tune your signal till you hit the sweet spot. What sets the SCR-DI apart from the rest is its Bass Scrambler Overdrive, which can be used in a variety of ways; a tiny bit of drive brings out some subtle upper-level harmonics, while cranking it all the way up can result in some grinding, alt-rock sounding bliss. The unit also comes with an 1/8 aux input so that you can play along with signal routed from your computer, mp3 player, and more.
