Did John at Solton check your seriel number? This is very important because if you have a lower seriel number, you have to add a small jumper cable. I have installed over 30 vocalizer boards and have not experienced any faulty ones. It's so easy to do as you have seen once you take out all those damn screws!The pedal board issue I have once noticed before and all I had to do is open up the bottom and I saw that the contact on one of the pedal switches was not making contact and all I had to do was re-align the switch.
