What owners have said elsewhere

Paraphrased from 151 discussion threads among 6 owners, 2024. No names, nothing quoted.

Owners are impressed by the SY-1, several calling it unreal and far more powerful than smaller synth and organ pedals, and a great tool for finding new sounds and ideas. It works for bass as well as guitar. The main limitation owners raise is that it has no preset storage, which is why some upgrade to the SY-200 for its memory slots, but they still rate the SY-1 itself highly.
