Backline 115 bass amp

[jeffyaeger]

My Gallien krueger backline 115 bass amp was working great and then one day I tried to turn it on and it was like no power was going to the amp. No lights came on, I checked the outlets, I checked the connections, but just nothing. Does anyone know what might be the problem?

Check the fuse in the back. If the fuse has blown, replace it with the exact value fuse. If the new fuse blows immediately, you have a bigger problem. If the amp stays on, you're probably ok.

How about the mute for tuning switch on the left side of the front?

Can't be that. He said "no lights coame on". Tuning mute has a big red LED.

Okay. But, site manual info doesn't show any fuse, or refer to one. I know my GK MB150 doesn't have any. Has a thermal breaker inside.

 

Here's a thought: My MB was "abused" by someone. When I got it, it made no sound. Turned out to be the FX loop jacks, which are supposed to short to internal loop with plugs removed. All it took was a tweak on the jack finger. Previous owner claimed it just quit.

 

 

Edit:

Still should be a power light, huh?
