Query: So, you want a Flanger.

I was looking for that deep churning that one hears on VH's "and the Cradle will rock". While this one doesn't sweep quite as wild as that, it does flange and has decent sound quality. IMO it sounds much better than the price. One concern that I have is that the unit is very compact and knobs are in harms way when feet are ready to pounce. Care is required here. Physical strength of jacks, switches and knobs do not appear to be nearly as sturdy as Boss, more like the Arion (jacks appear to be pcb mounted.) I would recomend this for someone who wants to try a flanger pedal (or as a backup) and is not inclined to tinker with the circuit as it appears to have few exchangeable components. (There are a couple of chipsets visible but they are very small and I wouldn't imagine being able to remove and replace them without doing PCB damage.) The DJ-8C satisfies my basic flanging needs to cover most tunes and has acceptable sound quality. No complaints for $21.
