i have two X-Series pedals, the XDD DigiDelay and the XMC Multi-voice Chorus. the DigiDelay is worth every penny, i got a brand new one for $70 from a guitar store in downtown Seattle. there are lots of cool features/modes like the ring mod delay, tape delay, 4-second sampler/looper, etc. the resonance is good and it really serves its purpose to say the least, and then some. rating: 9/10
i got the XMC from the same store for around $60, also brand new. the there aren't really a lot of tweaks that you can do here, and the output sound seems a bit muddy. but for its price, it's already a decent chorus pedal. rating: 7/10
