Rumble 500-- fix line out?

[agedhorse]

I'm right there with you-- the sound engineers I work with don't like it when you change the level of the signal you're giving them with no warning. This may be different when you're making gobs of money and melting faces worldwide, but I like to keep things as predictable as possible for the people I work with.

It depends on your needs and your abilities setting up your rig. Sound engineers don't like it when you make changes that make no sense, come out of the blue but generally don't have problems when the changes are associated with the intended levels when changing channels, when switching in and out overdrives, or when micing a bass rig (which is also post master volume. The bigger issue is if the voicing you have on stage is close to what's needed in the mix.

It's all about appropriateness, every situation is different. FOH engineers don't care to chase a player's level all night when it's inappropriate and not part of the intended tone.

I've done it both ways, as long as the player is reasonable and intentional, it's no big deal.

Don't forget that first "Master volume" knob - the one on the bass? It affects everything downstream, but I guess no one touches that knob during a performance?...

I've got a passive bass. I never touch a volume knob, except to 'mute' the bass on breaks. Otherwise, full volume, 100% of the time.

Yea, I was kind of kidding and thinking more of those with a passive Jazz that might want to favor Bridge or Neck for different tones....

Any bass player needs a direct box. Here are 2 cheap ones. I have the Whirlwind and it is OK and does the job.

The standard and one of the best ones is the Radial JDI. I have one and it sounds a bit fuller than the Whirlwind but the difference is not night and day by any stretch of the imagination.

The Behringer is a copy of the Whirlwind. Probably uses a different transformer, though. I gave one to the pianist I was giging with because the DI on her stage amp sucked and the piano had to go into the monitors anyway. Get the Whirlwind or a passive Radial (I have two Pro DIs) and be done with it.

In my experience, sound engineers prefer the DI box feed over the DI out from an amp.

So I will just +1 the DI recommendation. My Broughton Messenger DI out has never failed me or gotten any complaints from a sound guy.

Yes, they look almost the same and probably perform the same. It has been my experience with Behringer that it works just fine until it doesn't.

This very much depends on the amp and the DI routing.

Looks the same is to make customers THINK it performs the same. That’s the purpose of knocking off the cosmetics of any product.

Oooof.

I'm gonna have to disagree with an amp that doesn't isolate its on-board DI output from the master volume.

Just putting that out there.

I'll show myself out.

I'm going to guess that designing it that way allows you to slave another amp to it and after setting the levels once between the two, any change in volume done on the Rumble 500 (master amp) would carry through to the slave amp instead of needing to re-adjust the level of the slave amp.

On a bunch of the Eden WT amps, you can use the headphone jack as a line driver (was designed for that) and again, once set up to the desired balance of levels between the amps, any change you make to the level of the master amp will carry through to the slave amp. However, unlike the Rumble 500, when using those same amps, if you run the line out of the effects-send/out to the effects-in/return of the slave amp, you will have to readjust the slave amp level any time you make a change in the level of the master amp.

The Eden class D amps do not have that ability but many of the Eden WT amps do. I found that quite convenient when I was slaving a GK amp and cab to my Eden amp as a matter of course back in about 2008. No idea why else they would design it like that.

LOL...good point. I never think about using it because my bass is a passive Jazz and I actually need to run both volumes maxed out to get the sound I use. That is a decent option on my active 5-string though.

Slaving Rumbles does not need to use the DI at all. Just patch the effects send on amp #1 to the effects return on amp #2. The knobs on amp #1 now control both amps. The effects send is after the master and the four band EQ. The XLR DI output is after the effects return. So the DI is definitely not there for slaving.

Hey, all. I've been playing a Rumble 500 for about a year now-- love the light weight, sounds pretty good, reasonably flexible, and did I mention the weight?

But! It has a huge problem! The Line Out is post-master. If I need to adjust my stage volume for monitoring, then the FOH engineer will need to fix my levels in the mains. On very quiet stages, eg with acoustic groups, my level is too low to send the board a decent signal.

So, has anyone modded a Rumble 500 (or other Rumble; presumably they have similar preamps) to have a pre-master line out?

If the FOH is an “engineer” they should have several DI’s onsite with them IMO.

I have a Rumble 500 and was having the same issue with the DI being post-preamp. I bought a Sansamp Bass DI to solve the problem. i can dial in a bit of EQ before the FOH gets it, and use the unprocessed out from the Bass DI ("parallel out") to feed the amp. The bonus is now I have a great preamp/DI if I need to go sans-amp.
