Honestly this thing is sweet. Kills all the hum and buzz from those cheap single coil pickups(my case). Works great right before any effects and with the little bit of loss of highs you can easily get them back with an eq. It uses the overly famous JRC4558D chip inside. for what i don't know
Reliability/Durability:
though this thing sounds great, that damn on off switch is very flakey. But I think that is an issue with all the 9,L, and 10 series beyond that, this thing has worked perfectly
Ease of Use:
It has one know and a footswitch. doesn't any simpler
Customer Support:
its basically vintage now, good luck
Overall Rating:
well beyond what's been said, theres really not much more than that. This is a really great pedal for killing that hum your pickups output and like i said works great right infront of all your effects and is pretty cheap on ebay, along with all of the rest of the 10 series - I like them alot
