Ampeg SVT-3 Pro issue.

Yeah I tried all that.

What specifically do you think it could be?

[bass12]

Have you tried using both the Speakon and 1/4" outputs (separately of course). Could be one of them is not working.

[B-string]

First place I would look is solder joints on the input jack. From there it would be tracing the signal through the stages till the point of failure is found.

[gravyhighway]

Yeah I tried the input jacks. Since I got sound thru the effects return I figured that wasn't the issue. I'll look more closely at the input jack on my lunch break.

[B-string]

If the nut on the input jack is not snug, chances are good the solder joints could fail. Non-lead solder is more brittle, but required to be used in new production.

Do you own a Tech21 Bass Driver or VTBass? You could put one of those through the effects return and bypass the preamp section if you're in a pinch. Heck, you might even like it better.

I have the mxr bass di+ which I was thinking I could use if I had no other choice

Yes, that would work too. As long as its simply a preamp issue. The MXR is a good idea and can function as your preamp until you get it worked out.
