Location: Portugal | Hello everybody
I just got a beautiful used Ovation 2771AX Standard Balladeer which sounds great but there seems to be a problem with the OP Pro Pre-amp. The battery is new, the tuner works fine but I just can't here the guitar when hooked up to the amplification system. If I apply pressure on the OP then loud popping and crackling noise comes out of my PA system. It's as if the contacts are faulty.
I pulled out the can and checked the 2 jacks and they are hooked up correctly. The weird thing is the crackling sound when I press on the pre amp, as if there was a bad contact. I do not know if the problem is with the preamp or the circuit board in the can. I attached a photo of a similar preamp
Has anyone had this issue before or is there any troubleshooting steps I can take?
Thanks in advance!

Location: GATLINBURG TENNESSEE :) | Hey! I’m having almost the same issue with my VIP. Good idea Al... I forgot that contacts can sometimes become corroded. If not, I’m tempted to tear into mine and look for a week solder joint. |

Location: Portugal | I tried spraying the contacts and no luck. I friend of mine swiped a capacitor which looked bad, but the problem still remained. It seems that many people are complaining about this preamp becoming faulty, so I hope that Ovation has fixed this in the newer ones. |
