Rocktron's Utopia B300 Professional Bass System lays an arsenal of fabulous tone and effects processing right at your feet. The B300 floor pedal is packed with 128 fully programmable presets to transform your favorite bass amplifier into a multi-faceted rock and roll factory of sound. It comes with a plethora of popular effects like Chorus, Reverb, Delay, Pitch Shift, Flanger, Phaser, Wah-Wah and Tremolo, with the option to assign a factory preset or a user-created one to 10 buttons. A Global function allows setting parameters that affect all presets. A Mixer function lets you tweak volume, output, pan, delay, reverb, and overall effects levels. The Preamp function not only gives you four preamp types - Deep, Norm, Brite, Distorted - as well as other sound-shaping choices like standard 3-band EQ options, gain, presence, symmetry, polarity, and more. The Rocktron Utopia pedal also has a HUSH function which is a single-ended noise reduction system, and a Speaker Exciter function that provides a realistic approximation of a miked speaker cab when you are connecting the Utopia B300 directly to a mixing board, recording system, or other full-range system. You also get a compressor function, effects loop, and seven tap quantizing choices. As far as I/O, you get MIDI in and out/thru, an aux jack, stereo headphone out, USB, 1/4" mono bass input, and 1/4" left/right output jacks. All in all, it's pretty safe to say the B300 multi-effects pedal gives you a lot to work with.
