Had my combo at a gig tonight.....and the thing started to red light....or clip/lim light was going on, and the sound was fading out......

I was so pissed......cause I wasn't pushing the amp at all.....am using a passive p-bass....

Any idea what the problem might be?

A couple of thoughts...

How loud was the band? What kind of music? Did If you have any PA support? Maybe don't have enough speaker for the task? If you drive any amp hard enough, it's will sound bad.

Were you using anything in the effects loop, any pedals, compressor, etc?

With more information, maybe I can help you pinpoint the cause.

Thank you.....we had a gig at a very small venue with a Blues band....medium loud.

I use a passive 57 RI p-bass.....no effects, no pedals...no need for PA DI.

I use a high grade Phil Jones bass cable.......

In any case I just bought the unit, so it's still under warranty......I will try again next week, if it petters out again.....back it goes.

Thanks again for your replies.

if you could let me know the settings on your amp, that will help....in o'clock format.

Also, eventhough I'm not saying one of our amps can't have a problem with it, the power supply at clubs can cause problems.

Even combo's which are built to sound good, can be pushed to the point where they sound bad. Eq settings are usually the culprit. Too much low end will kill you. But, my original point was, one 12" speaker is usually not enough to stand up to a rock gig on it's own. Maybe consider adding another 12, I bet that cures all.

I agree about the 1x12 not being enough for a gig situation with a drummer and no PA....in most circumstances. It still shouldn't be cutting out though.

OP- can you give us all your settings?

I believe the settings were:

Gain : 8
Pre amp Volume : 8

Active Equalization
Low : 3:00
Mid: cut 11:00
Mid Freq : 12:00
High : cut 11:00

Signal shape
LF Boost : oN
Mid scoop : on

Master Volume
ABOUT 8 OR 9

I'm afraid I don't understand. In "o'clock" format, 8 or 9 on the preamp gain is barely on.

Looks to me like he's referring to 8 or 9 out of 10 because he uses the *:00 format elsewhere.

If that's the case Roger, any idea what the problem would be?

:D

Just kidding...I know what the problem is...you're trying to kill it! Just because the dials turn that far doesn't mean that you should turn them that far. You've got a single 12". With all due respect to Roger and Andy who make a wonderful and very loud 112 cab for the Shuttle, it's only a single 12". Not only that but you're boosting the bejabbers out of the low end, and that's a recipe for blowing a speaker at those volumes. Yes, they do design them to "take it," but you have to be reasonable about it and not expect miracles out of a small cab.

Given those settings, and an average ouptut level bass, it looks to me like there's enough "knob twistage" to easily overrdive the amp by roughly 12dB if playing reasonably hard. That's quite a bit, and looking like not enough speaker for the task to begin with, but maybe needing more amp and speaker.

I would first suggest trying a 410 cabionet out, that would help with the low eq that's being boosted. Then I would look at maybe 2 x 410's at 8 ohms and that should get plenty thumpy, freeing up amp power (by backing off on low eq) for even more volume. Another possibility is to try another 112 (either the Shuttle extension or better yet the NeoX-112) which would extend your low end and increase your total output power into 4 ohms by almost double.

Where's the tone controls on your bass... active tone controls w/ bass all the way up by chance?

Master volume at 8-9 with the low boost and mid scoop both on?
You'd do well to learn how to properly set your amp and you'll have more luck avoiding problems.

I'm using a Shuttle 6.0/12 with a 12 extension and am thrilled with it. We play a bit too loud on stage (60's and 70's rock) and I don't have any problem. I've never found a small amp so capable of doing my gigs, but if I set it like the settings listed above, I'd fully expect it to blow up.

This reminds me of a funny story...

I was in GC one day last year, and this guy and I got to talking. Seems he'd bought a small powerful 112 combo that shall remain nameless. He was upset because it distorted. I asked him to show me how he sets it. He turns the bass up almost all the way, scoops the mids halfway down, turns the treble up to 3:00, puts gain at 2:00 and master at 4:00, hits one note and says, "You hear all that distortion?"

:eyebrow:

I spent a couple minutes trying to explain to him about how you can't do that, and he says, "Well if the knobs let me turn them up that far, then it shouldn't distort ever." I tried another copule minutes without any noticeable sign of him understanding a word I said, so I told him he needs to look into an 810 and made some excuse and got the hell out of there. Learned a lot about buying floor models that day ;)

OK, well I thought it was funny. Guess you had to be there.

That might be an issue with the power in that club. Or, it could just be that your drummer hits harder than you think. :smug:

I've gigged with both the 6.0/12 on its own and also with the extension 1x12, and I am thoroughly impressed with that rig. :bassist: :bassist: :cool:

Tom.
