Kinda a confusing question.....

Corvetti · #1 01-06-2011, 04:30 PM

So I bought a GK MB500 head and an Ampeg 810 cabinet, and I noticed on the low B when I play really hard on it it it kinda has a little bit of a farting noise but I don't know how to describe it really... its easier heard on high volumes, but I can also replicate it on each string, but its easier on the B string. I just have to pluck the other strings harder to make the noise, could the problem be that the strings are too close to my pickups? Or is it the 810 can't handle the low end of the B? I know the low end isn't supposed to be great on the 810... but I figured it'd at least handle it. What do you guys think the problem is?

Input distortion, bass setup, overdriving the preamp of your bass, etc. Lots of options.

Yup, could be any of what rp mentioned. My guess, input gain too hot.

What can I do to test to see if its specific things? I'm sorta a noob at this stuff. :P

I turned the gain way down to make sure it wasn't that and it still does it... but just at high volumes now.

Could it be the Countour knob on the head? I just tried turning that all the way down... I'ma see what that does.

Any other ideas? I can't seem to fix it..

You need to try to isolate it.
Bass-Set your bass flat, make sure the battery is good. Turn the volume down a little. Try a second bass.
Amp- Try the pad switch, only use the clean channel (master), set the amps EQ flat, keep the gain below noon. Your your cab with a different amp.

If that's not it, it might be the amp...is this stuff all new?

I am going to guess battery but it could be many other things.

Its all new stuff yes, and my bass doesn't use batteries. I'll expirement with that though tomorrow, too late to do it today.

What bass are you running through the setup?

Try use a compressor/limiter

It's possible that your speakers are farting out because they are reaching their excursion limit. This problem, if it occurs at all, is always most severe at low frequencies and gets worse at high volume. You will need to set the EQ for less low end, play at lower volume or lower gain, or replace the 8x10 speaker cab with for something better. Which Ampeg 8x10 is it? Ampeg 810E cabs are popular but they are from best handling low B at high volume. Try some other cabs.

A compressor / limiter will tame some peaks, but that may not help the problem as much as you need. It certainly could help.
