The DB30 from Roland’s Boss division is more than just a click – it is a valuable and useful tool which is easily transportable, and on top of all this, great fun to use!

With a wide variety of rhythms and time-keeping assistance tools, the DB30 can handle time signatures of anything up to 17 beats per measure. Furthermore, it comes preloaded with 24 different rhythmic beat patterns in a wide variety of styles, including (but not limited to!) unusual time signatures and Latin rhythms.

A headphone output with volume control adds a level of privacy to your practice, allowing you to sort out your rhythm even in the noisiest environments, while a smooth-gliding LCD needle is easy to follow with the eyes. Other useful functions include the Tap Tempo – which helps you to find the right pulse for your music quickly and effortlessly.

But it does not stop there. 12 semitones make up the internal reference tones, and Auto Power Off optimizes battery life.

With all of these features in one little machine, the DB30 is not only an essential piece of kit, but comes at a very affordable price too!
