New Rumble arrived today...dissapointed.

Its a passive jazz bass with two P bass pickups...should have lots of tons of low end.

If he's tried 3 different amps with the same results, the potential problems in order of likelihood would be.

#1. Operator error. Volume knobs on instrument turned wrong way, tone knob turned down, gain on amp turned too far down, etc...
#2. Defect in instrument.
#3. Defect in cable.
#4. Defect in some mid piece, tuner, effects pedal etc... between instrument and amp.
#5. Defect in operators hearing.
#6. Series of defective amps. Maybe the GC he is going to is dumping off defective returns through this location. Not likely, but a possibility.

Lack of lows, and lack of volume is without a doubt far outside of the norm for these amps. Something is very, very wrong, and needs to be looked at...
 
Bring back to GC, try compare with another unit side by side.
I am 100% disagree rumbe 500 lack of low. Maybe u are bad luck to get the defective one.

i will go to GC to get myself v3 100 combo this sunday, will try the v3 500/210 combo.

I think Dave is right. What are the odds of him trying 3 different amps, including this one that so many people claim to have plenty of lows and have the same result?
By simply going to the store and ask them to use another cable, bass and amp he would check all of the 6 above points and find out what the matter is.
 
Still no..............



Raising it up a little does not take

away your low end. All it does is raise your mids/highs up closer to your ears, so it just sounds like
less low end.

But it also depends on what type of surface you amp is on. Old wooden floor with an empty room below, or a hollow stage. Yes, this might be perceived low end, but it is low end none the less and when you raise your amp from these surfaces, the boominess or perceived low end will be tamed.
 
I don't own a 500 v3 but I've put easily 5 or 6 hours into one over the past month or so at my local GC. It is easily my top combo choice right now. I place my vote on that you've got some issue elsewhere than the amp. Try comparing it to another at a GC or something? The rumble 500 I tried had the most full, round and warm sound out of all the larger combos that GC had.
 
Your result with the Rumble 500 combo (lack of bass) is totally out of character. That combo actually has an abundance (over-abundance?) of lows. And it's quite a bit louder than the 200. Sounds like you mat have a defective amp. Check it with another bass. Also, hook an iPod up and see how it sounds - there should be plenty of bass and lots of volume.

Totally agree. If anything Fender's are sometimes criticized for having scooped mids. What your saying is the exact opposite.
 
That's what I thought through the 210 cab. The 112 made a HUGE, drastic difference. I absolutely would not consider the 210. I would consider the 112.

And FWIW, I was actively A/Bing the Rumble 500/112 with a Phil Jones Suitcase Compact/C4 (nearly all my gear is Phil Jones...), a GK combo (the 500W 210) and an Ampeg BA210 with a student of mine. Same room, same bass, same player (me). The Fender held it's own surprisingly well - as long as we used the 112. The Fender 210 cab didn't fair well.

I would be very interested in hearing more about the differences in the 112 vs the 210 Rumble v3 cabinets. I'm in the process of deciding between the two configurations and if you could add some detail to what you heard I would greatly appreciate it.
Thanks very much!

I have no dog in the fight, but I plugged into a Rumble 500 (not the latest model) at a local blues jam and it sounded pretty damn good, I didn't mess with the controls since it wasn't my amp but it sounded good on stage and out in the (smallish) club when the other bassist was playing. Something is amiss, either the amp or something up the chain.
 
NOT true..............

Raising your amp 12" off the floor will NOT kill your low end.

Wel, maybe not the AMP itself of course :) but but I tried raising cabinets and combos above the ground:
Ampeg SVT-410HLF, SVT-410HE, SVT-115E, PF-210E, PF-115E, Ashdown VS-112, AB610, GK Backline115 cab and combos Ampeg BA115, B-200R, GK Backline112, Ashdown EB-180 and the result was always the same - quite massive loss of low end.

I even remember reading some Markbass combo manual, which basically said, that for best low end response the combo should be placed on the floor.

Well then, I guess the engineers that actually design the cabs are wrong then. :banghead:
 
The blacktop Jazz has two PBass pikcups right? Try something with actual Jazz pickups - they give a more defined fundamental (read: BASS) - it has been said, and it (makes perfect electronic sense) bears repeating that one of the things the PBass pickup was designed precisely to eliminate some of the strong fundamentals that single coils produce that amps of the time (low power, open back) just couldn't handle. It produces instead a more mid-emphasized sound.
The other thing to do is turn up the amp (somewhere you can) and get AWAY from it by about 20 feet. With a cabinet that size the bass frequencies kindof "appear" a distance in front of the amp because of the difference in length of the wave versus the size of the cab - that's why traditionally loud bass cabs where large). You may find you have plenty of bass and just aren't hearing it when playing it up close.

The Fender Blacktop jazz sound nothing like a precision. And its certainly not middy, it has a lovely scoop with both pickups maxed.
 
I've encountered two dead Rumbles on the sales floor of GC and Sam Ash. One sounded like a cheap guitar amp with really terrible distortion. One was muffled and cut in and out and then went silent.

I did play through a 200 combo, and then a 500 head into a Aguilar DB410. They sounded pretty good.

In short I'd swap it out at your local GC. If its still a dud get a GK in the same or similar price range.

Good luck!
