I'm currently in the market for a loop pedal, primarily for home practice, and looking for some advice. Ideally I'd like something which can handle two instruments, so that I can loop a chord progression on guitar and play along on bass. As far as I can tell that rules out the boss rc-3, which is a shame as I think the built in drum samples would be helpful. The electro-harmonix 720 appears to do what I need, but doesn't have the drum samples of the rc-3. What do you use, and do you have any advice or further suggestions? Thanks in advance.
