Its a passive jazz bass with two P bass pickups...should have lots of tons of low end.
NOT true..............
Raising your amp 12" off the floor will NOT kill your low end.
Not all of it. But you will lose some.
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...
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.
try everything in GC and don't leave until the janitor punches in!
.....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.
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.

Wel, maybe not the AMP itself of coursebut 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.

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.
Try switching from line out to speaker out. It might get louder too.Yeah, I dont have the combo just the head into a gk 212neo, but I have to run the low knob around 9 o'clock with my jazz and completely down with my p/j's. Something is definitely not right.
