New Kid on The Carvin Block

Postby Wayne Damage » Mon Sep 03, 2018 8:48 pm

Hello, I'm the proud owner of my first Carvin Bass !! It's a beauty but only the passive settings work I have cleaned all the pots, and looked over the boards with a magnifying glass there is no loose connections, the 9 volt battery does go into the board but still no active presence where do I go from here :?: By looking on Carvin websites this appears to be a LB?? made in 99-05 bass is that correct :?: any help on the active situation on this bass would be appreciated

It's not unheard of that the preamps go bad. I've heard stories of people frying the boards by putting the 9v in backwards...but I don't know if that would still leave the passive function working. :think:

The only other thing I could think of would be to make sure that the "prongs" in the battery compartment are actually making sufficient contact, as some 9V batteries are ever-so-slightly smaller than others.

I think if you've looked for failed solders, and you've tried a fresh battery, it sounds like the only other thing to do would be to beak out a multi-meter and see if there's either a failed component, or some connection that's broken that you just couldn't see with the naked dye. :think:

Thanks for the reply Spudmonkey, I do have 9 volts going to the board but beyond that I do not know where and how it should be going, I just got this bass and it really is my only bass with this much active circuitry . The passive sounds great but I would like to hear the whole deal

All it takes is removing the battery with the cable connected to the bass 1 time.
We've seen several examples of these through the years of this.
If you or someone you know are good at electronics, it can be repaired, otherwise, it has to be replaced.
The good news is that the passive voice of their basses is so good it can be the only one you really need.

Thanks' Praiser, I've only had this bass a week so somebody probably did just as you mentioned. I played it for 4 sets last weekend and didn't even pick up my other jazz bass (with joe bardens) and loved the sound of the Carvin, but if any body out there knows how to fix the active issue please let me know

Yeah, it's a replacement of the module.

"Call with credit card in hand" and you will likely get a "yes".
