The Tech 21 SansAmp RBI rackmount bass preamp opens up a world of possibilities for the bassist who needs a variety of tones to choose from. The preamp’s drive enables users to crank the gain/overdrive in their signal, while presence coaxes out the attack and harmonic content in the upper register. The RBI also comes with a dedicated Mid control to give you a tighter handle on the meat of your tone. The preamp’s Blend feature allows you to mix the direct signal from your bass guitar with the RBI’s SansAmp Tube Amplifier Emulation circuit. Also included is an Effects Loop, along with an accompanying 50/50 switch that allows you to configure that input in series or parallel.
Whether you’re a regularly gigging bassist or a studio session player, you know that it’s important to be able to capture a variety of tones in your performance. The Tonebone Bassbone V2 bass preamp is designed to do just that, with two channels that each feature their own powerful EQ settings and level controls. The preamp’s 3-switch stompbox design makes it easy to jump between channels as well as the control effects loop and boost. The Bassbone V2 also comes with a built-in DI, making it ideal for live and recording environments. The unit’s separately buffered tuner output works in conjunction with a mute footswitch that makes it easy for you to tune your instrument while onstage without letting the audience hear the process.
Tonebone’s Bassbone OD bass guitar preamp provides two channels that you can use in one of two ways; you can run two separate bass guitars through it, or you can opt with one but have an instantly-switchable A/B setup for your sole signal. The unit features a bass overdrive effect that allows you to dial in just the right amount of bite to your tone. 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.
