I have an Akai Deep Impact, but have not used it much. The band I'm playing with will be doing some tunes that would allow me to use this effect. In the past, I've notice a couple of problems with this device. Please note that I power it up with the original power supply and use very good cables. 1. The effect completely cut off any signal to my amp. I checked and double checked all the connections. Once I physically bypassed it by physically disconnecting it from my board, my sound came right back. That happened once, then it started working again two weeks later when I went to check it out again. 2. Just prior to sound check, I click on each pedal individually, check the sound, then click each pedal off and go to the next pedal. About a month ago, I turned on the DI, checked a couple of my presets, but then I couldn't get the Deep Impact to turn off. I had to bipass it again by physically removing the DI from my pedal board. I've read some posts about some original cold soldering joints that are "touchy" needing resoldering at a local electronics expert. For those of you who have had this effect repaired: 1. What do I tell the serviceman? 2. Did the servicing of this device fix the reliability issues? 3. Do you still like your Deep Impact or like it more now that it has been serviced? This effect is now completely off my pedal board, but I'd like to get it going if it can be made to be reliable. I don't need surprises just minutes before a gig. Thanks in advance for your replies.
