I myself find metronomes a bit boring, although it is really an essential element to develop your timing and ability to play along with others. I have two pedals that combine the metronome with options. The first one is the JamMan Solo XT. It is a looping pedal, which allows you to layer levels of play, and it also has a rhythm feature that you can use as a beat measure. It can be adjusted for many options like a click, snare, tap, or a number of other beats. The other pedal that I have that is an extreme amount of fun is the Bandmate TRIO. After you lay down the timing and the chord sequence it will give you a lot of options for a drum beat depending on the style of music that you select. It also has a basss guitar that will play along with you. You can control the loudness of the drums or bass . It is really fun to play along with, and it gives you a little sense of how it would be to play with others, while developing your timing.
