its great! tight analog sound. I have been a dd5 and 6 dude all the way til I found it, but this thing sounds great. different sound and feel. The pedal doesn't mess with my tone or volume when in use. I'm playing it through a mesa boogie dual rectifier, with a slew of pedals, through an Ibanez 421.
Reliability/Durability:
its cool... dependable? yes.
Ease of Use:
Super easy to use. has three control knobs, delay mix repeat.
Customer Support:
who needs that?
Overall Rating:
I must say it was a great pick up for only 60u.s. bucks. Comparable to using a Boss dd-3... Only if the sound of the dd-3 was translated as blue, then the fx90 would be red.
