Fender Rumble Club

[USAJO]

I guess I thought this forum was for Rumble owners.

Here’s my question.

We have a new Fender Rumble 100 in our practice studio. I play a Fender American Jazz.

I’ve never had or played through a bass amp that I pegged the treble and still don’t hear enough high end. I’ve never actually played any amp with the treble full on.

Is this just how Rumbles are voiced or do you think something is wrong with this new amp.

Other bands use this amp and when I come in for rehearsal they have treble set full on so I guess it’s not just me?

do you find you need to max treble? I’ve never had to do that on any other amp. Usually I cut treble.

Would it be possible to adjust/shift the frequency of the tone controls so 12 o'clock is the actual measured flat EQ instead of having to set the tone controls to 10-2-2-10? It would be nice to be able to adjust +/- the full db range of each knob.

I don't know a way to adjust the frequencies but, perhaps you can adjust the orientation of the knobs! Or replace the knobs with adjustable orientations.

REORIENTATION: Set the existing knobs to 10-2-2-10 and remove them without turning them. Then replace the knobs, but oriented at 12 o'clock. Presto! Abracadabra!! 12 o'clock is now actual flat! (But their minimums & maximums are now different. Min = 9-5-5-9 instead of 7-7-7-7, and Max = 7-3-3-7 instead of 5-5-5-5)

Many of us play bass, not treble IMHO.

Agreed. That was my solution as well a few posts back. If one does not like the EQ of Rumbles, they could always buy an EQ pedal of their choice and run it through the FX Return. Of course, that by-passes the Rumble tone stack and begs the question of why you bought a Rumble in the first place.

I am happy with the Fender tone and using my ears rather than a clock ...

Not sure off the top on my head but I think the stock knobs have matching "D" shaped receptacles to match the posts. There are replacement knobs available that have a screw to tighten in, I guess, whatever position you want them.

Looking at the graphs published here by guys who put their Rumbles on the Dyno, treble is already boosted above the mean. Additional treble is "theoretically" available with the EQ AND Bright button. But seems to me that it would be somewhat moot since you'd be boosting frequencies above the bass spectrum. That is if I understand correctly that the bass harmonics extend to ~4khz.

I’ve never been accused of playing guitar on the bass. That’s why this is so surprising to me that others using
the amp also must be having trouble with the EQ and are maxing out the treble.

I don’t like a lot of treble but I can’t back the treble off at all because it just isn’t there.

I’m shocked by this.

67 TR4a. I figured when my gigging days were over I’d sell all my musical stuff and do a partial restoration of the TR4a.

I’m shocked to be still playing at my age. Tribute bands and making the most money I’ve ever made and plying to large crowds. Go figure. To quote Joe Walsh “I’m just lucky that way”. I’m very mediocre but can sing….kinda sorta.

Love my Triumph though. Got my first one in 1969.

I have a lot of noise from my Rumble 100 when I turn on the bright button.

Obviously, the more I raise the gain and master the more noise there is. But with the bright button ON it's really too much. I'd say unusable. Not I that like or need that extra brightness, but it bothers me that there is so much noise as a result.

I doubt it's a defect because everything else seems ''normal''. It seems like a design issue.

Do you guys have the same problem?

Not necess-celery, JO. Sure, most of us own 'em. But we also try to help others get the best out of 'em.​

So, the Rumble 100 belongs to the practice studio and its use is included in the rental? Did the studio spokesperson tell you it was "new"?

Have you tried turning the Treble knob back and forth thru its full range to make sure the pot isn't just stuck? Does turning it produce any crackling or static? Does engaging the Bright button help anything?
​

... ... ... Here’s my question. Is this just how Rumbles are voiced or do you think something is wrong with this new amp.. do you find you need to max treble? I’ve never had to do that on any other amp. Usually I cut treble.

No, my Rumbles can easily get plenty more Treble than I care for. Assuming you, and the other bassist(s) using it, are not hardcore metal players, you shouldn't have to peg the treble to get enough. It does seem like something is wrong, but could be just a dirty knob potentiometer or a PC board problem.

Ask the studio if it is still in the 2-year warranty and could get a free repair/replacement at an Authorized Fender Service Center? Or is it actually a "bargain" used item they got for window dressing? In that case, will they have it checked by a reputable tech? Otherwise they should reduce the rent for the unsuitable decoration.

The rehearsal studio is owned by one of the members in two bands I’m in. He also works with a couple other band. (Crazy)

So he bought the Rumble for the bands that rehearse there. Brand new. No not metal just rock.

Always loved the looks of the TR6 and the Austin Healey...

So, if your car has a flat tire, and everything else works, does that seem like a design defect? ​

My Rumbles don't have that problem. Seek [This invalid link has been removed] if available. Otherwise, see a reputable tech, preferably an Authorized Fender Service Center.

Yep. Me too. Back in the '70s I owned a '66 Sunbeam Alpine. That's the closest I ever got. GOD, it was fun to drive...when it ran. Selling it was one of the best days of my life. Those Stombergs used as much oil as gas. And couldn't keep them in sync to save my life. But did I mention how much fun it was to drive..?

Please let us know what he says about getting it repaired/replaced, if turning it doesn't help.

It sucks having to send it back. I bought it new on the internet a couple of weeks ago and haven't used all its features that much. I just like to use the vintage. I'm gonna try to find another just to compare before sending it back.

Yep, fun to drive when you can. Carbs, electrical problems, cost of repairs...all reasons why I never owned one. Great looking, though!

You have to accept you will always be fiddling with them to keep them on the road. You have to enjoy that part of it too. (Unless you’re very wealthy and have someone do it for you.)
