I'm not sure this is the correct place for this, but I'm so excited about this product I had to get the word out. I am one who feels practicing with a metronome is crucial to good time and execution on the gig. The relatively new DB 30 metronome is the best unit I've come across. It is tiny.... 3" by 2" by about 1/2" deep... but is as 'full function' as the DB-88 (the long time standard IMO). It has a loud 'click', along with flashing 'beat' lights and a very nice digital 'swing arm' that mimics the old mechanical metronomes. It is totally and, most importantly, easily programmable 'on the fly' for many different standard and odd time signatures and different grooves, and can be programmed for quarter, eighth notes, etc. It also has a headphone out, so you can plug it into the second channel of a headphone preamp or amp for louder practicing. Its size allows it to be kept in a gig bag pouch for use at all times. It's about $40 at Musicians Friend. Truly amazing product IMO.
