some zoom Bass/git effects have metronome din. I've used a zoom RT123 Drum machine before and is planning to get a newer model if kaya ng budget ko.
I used to play in a full band and i am a bassist but I also tinker with percussions and the drum machine so when we do gigs at a bar in proj 6 before... sinasabay ko yung drum machine for effects but i only use the congas, bongos, clicks, and some uncommon sounds when we play para di ma-sapawan yung drummer namin.
