Earlier this year, I swapped my Trio+ for a bandmate's Beatbuddy for a few months and was impressed by its intuitive interface and high sample fidelity. The pedal is easy to set, its screen easy to interpret, and its essential functions easy to operate. If you have MIDI experience, loading and/or creating new beat patterns is a simple procedure, and the pedal is capable of high-level functions such as midi clock syncing with other midi-enabled pedals.
Grievances: the built-in samples are a bit "forward" for most acoustic settings, and the included rhythms are stretched thin across a wide variety of genres. I often found myself wanting to create my own rhythms, but the Beatbuddy is designed for practice/performance rather than creation, and I lack the midi experience necessary to plumb the depths of its capabilities.
Addendum: the rhythm-focused nature of the beatbuddy is probably a better match for the electric guitar in general. Acoustic guitars and 'ukulele can already render many rhythmic patterns acceptably well, and the 'ukulele in particular generally benefits more from bass accompaniment.
Overall, I was pleased with the Beatbuddy. It brought to light some of the flaws with my regular practice aids, and I'm now considering creation-focused rhythm solutions such as the Digitech sDrum, a drumpad and step sequencer, or the Boss DR-01S.
Aquatopaz, there used to be an active beatbuddy user community that generated quite a bit of downloadable content (both free and for purchase) for the device. It may be worth looking into.
