Since the earliest days of the electric bass guitar, players have desired a balance of portability and sound. Genz Benz’s Shuttle 6.2 captures those qualities in a modern package.

It’s quite small, about 3/4 the size of a rack unit, and weighs in at under four pounds. Its Class D design is very efficient, meaning high audio quality with a small size. There’s plenty of power; at 8 ohms, it’s pushing out 375 watts, at 4 ohms, 600 watts. A 12AX7 is in the preamp stage warming up the signal. 

The front panel features a mute switch, gain and volume controls, while a 4-band active EQ provides sound sculpting. The two center mid frequency controls are parametric, and can perfectly adjust the mid frequencies that can make or break a bass sound. There is also a “shape” selection: low frequency boost, a mid scoop or a high frequency attack selection. The rear panel has an effects loop, aux in, tuner out, headphones, and a footswitch connection for the signal shape controls. The XLR DI out has plenty of options with a pre- or post-EQ out, and line level or mic level output, giving it plenty of flexibility in a live setting or in the studio.

With a flat EQ setting, there’s plenty of fullness, and adjusting the EQ for the room, type of music, and bass, is easy. It’s hard to get a bad sound out of it. Even an inexpensive bass sounded high-end through this unit. There’s a great balance of warmth and clarity, and plenty of useful low-end frequencies. The shape controls are a great feature, eliminating the need for external boosters or EQs to get a low-end sound to stand out in the mix.

The only downside is the choice of speaker connections. While the Neutrik connections are lockable, which is nice, forgetting or losing a specialized cable, especially when you need it, with the inability to use a regular 1/4” speaker cable is also a bummer.

Overall it’s a very nice, modern bass system. It’s quite portable, size and weight wise, and delivers a fantastic sound. Highly recommended for any live or studio bassist.

    Good review!
    Genz Benz is a great product supported by wonderful people (the Genz crew!).
    About the speaker connectivity, in todays world who even owns a 1/4″ speaker cable anymore? 🙂
    Only very old cabinets still use mainly 1/4″.

      I have had Shuttle 6.2 for almost 10 years, put alot of miles on it and still working great. Like anyone else, I am picky about my tone, I am happy with everything close to 12 o’clock. I use it at 4 ohms through 6 Eminence for shows, it absolutely rocks. Through my 2 10 cab it is excellent studio sound with my Fender Jazz. Love this amp.
