I'm still discovering new combinations, in settings, with send/return and in the chain. It's really easy to dial in a nice sound, the tone and gain are a bit tricky but with a bit of fine tuning they add nice character to the sound. In complete normal settings (no tone/gain) it does not self-oscillate. The modulation is a nice feature and if this does not modulate enough, you have the build-in effects-loop where you can place other modulation, pitch, tone or distortion pedals which only affect the trailing delays. For the price there not a pedal I can think of which brings that much inspiration for soundscapes combined with great sound qualities and build quality. Sometimes the pedal glitches, but with a bit of practice you now when you run that risk and how you can recover... a good power supply is needed though.
