I am using this with an old Conrad Acoustic/Electric with a Ibanez CF-7, EH Memory Man delay, BOSS AD-3, and a boss overdrive into a Kustom K25-2 amp (yeah the old white/black vinyl covered amps). I rarely use it anymore because it has a very generic sound. With some tweaking you may get an early metallica sounding distortion. turn up the gain and you can cut through solos pretty well.
Reliability/Durability:
I had problems with the first one i bought. it would switch over to distortion, and the one i had now had problems once. Its built like a tank but the insides are weak. Use a backup in a gig.
Ease of Use:
Very easy to use and set up. A must get for beginners who want distortion or something to switch their guitar over from clean to dist. quickly.
Customer Support:
I never had to deal with them, i just took it back and got a new one.
Overall Rating:
Like I said, its a nice pedal for beginners, and if you dont want to spend alot of money. I'm tempted to sell mine to a friend who needs a cheap distortion box. Overall its a decent pedal but dont pay more than $45 because you could get a better distortion for a few bucks more. If you buy it used dont pay more than $25.
