Display Has Problems

Posted by JR from San Diego on Jan 16, 2010

Experience w/product: I own it

Reviewer's Play Style: Jazz, Pop

The unit works fine, but when I turn it on after it has been off for a while, the display does not work. It needs to warm up considerably for the display to show current settings. I sent it back for warranty repair, but it was returned to me saying the technician could find nothing wrong. It definitely has a problem. Other than that, the effects are every thing I expected.

Reviewer's Play Style: Totally opposite of AMERICAN IDOL?

I purchased one of these about 8 years ago. In a bout of insanity, I dissolved my studio and GAVE this thing away (along with a ton of other equipment). Now I'm building a new studio digital and all, and I am purchasing another one of these FX units, that's just how great of an impression it made on me!! I wouldn't be without it.

Awesome Multi-Effects Processor!

Posted by KevinDean from Orange County, CA on Jan 3, 2009

I use this processor for many effects: Delay, Reverb, Flanger, Tremolo, Chorus...it's awesome for the money! I like the ability to modify the many preset sounds, and save them for future use.

The only thing I would change is the ability to use the "Tap Tempo" function and the "Bypass" and it allows for only one or the other, so I usually end up locking in the Tap Tempo during practice and then changing the utility function to Bypass when playing live.

One last point, you can use it in your chain without needing an effects loop in your amp. That was one of the reason I purchased this as I have a great, little 15 watt amp, but it does not have an effects loop.

Overall this is a great, dependable processor and at a great price.

We have used this in our band and reaped massive rewards with our sound years ago. I am back to buy another for my son to enhance his interest in the guitar. At 14 years old, he is very creative and expermental. With this product he should find his recipe. I'd love to do a humorous, intellectual and economic commercial with you covering this product.

I've had an older unit since 1996 and it has functioned perfectly. For home projects and scratch tracks where getting the idea down is more important than subtlety this machine does the job very well. Also delivers solid live effects.
