Tascam CDBT1 mkII Bass Guitar Trainer
The Tascam CD-BT1 mkII is the new version of the popular CD-BT1 that travels alongside professional players from Rhonda Smith to Reggie Hamilton. The CD-BT1 mkII now features Bass Enhancement including Bass Cut and Bass Boost, more variable speeds, built-in metronome, more controls accessible by footswitch and much more. If you can operate a CD player, you can use the CD-BT1mkII. Take any standard compact disc by your favorite band and put it in the CD mechanism. Then plug your bass directly into the CD-BT1mkII's 1/4 inch input. Put on some headphones, set the volume, and start rocking! If you're a vocalist, you can do the same, substituting your microphone for the guitar.
Slow Down and Learn with Slow Speed Audition feature.
In ancient times (like the 1970s), musicians would take a vinyl LP record and manually spin the record on a turntable, slowing it down to be able to better hear and understand the performances, like bass solos and complex chord changes. With the CD-BT1 mkII, you get a training method that's even better. Not only can you slow down the speed of the CD by up to 50%, but you can do it without changing the pitch of the original material! After you learn the lick at a slow speed, you can increase the tempo in steps until you can match the original performance note for note. Also, you can change the pitch of the CD without changing the speed...use this feature to tune the CD to your instrument.
Effect Yourself
The CD-BT1 mkII has 16 great-sounding built-in customizable bass effects...you don't need to turn to external boxes for chorus, EQ and more. The Bass Boost and Enhance settings allow you to boost the bass part so that you can hear it better, and Bass Cut lets you mute the original so you can play along.
Performance Tools
You can set seamless in-out loop points with the CD-BT1 mkII...it will play the same section of music over and over again so you can focus on your playing. Use the footswitch input to start and stop the CD, or to scroll through effects. The CD-BT1 mkII even provides a chromatic tuner so you always sound great when you play, and can run on batteries to take your show on the road. You can listen to the CD-BT1 mkII via headphones, or use its Line Output to plug in speakers.
There's never been a better or more affordable bass training tool than the CD-BT1 mkII. |
