You are trying to do something that isn't supported at any level. If you blow up the front end of the R40 by plugging R100 EFFECTS SEND to the R40 instrument INPUT, I'm betting Fender would be able to detect that and deny any warranty you might be trying to claim. If you are trying to feed the R40 through AUX IN, you probably won't blow anything up, but I wouldn't expect much. Everything I've said here can be deduced by looking at the block diagram. If you can't make sense out of the block diagram, I STRONGLY suggest you restrict your usage of the amplifiers to what OWNER'S MANUAL says. Unless you just want to experiment and have enough money to buy more equipment after you ruin yours.

Appreciate the info, I thought effects loop was an instrument level signal. It was just an experiment - nothing was damaged, but I won't try it again.

RedVee - I think the other experiment was Effects Send from one amp to Effects Return on the other amp, not effects send to Input.

Cheers,

After I posted I took a look a the manual and there is a significant difference between effects loop and input. "Input" is MOhms, while Effects loop is kOhms, so effects send is a somewhat "hotter" signal (more current/amps).

With the R40, I had been putting my (few) pedals between the instrument and amp input, but with the R100, I will try running them through the effects loop to see how that works.

Though I now feel like a dumb butt, I did learn something today!

Cheers,

I'm all for experimentation, but [pre-amp out] to [pre-amp in] is one which has a higher-than-average chance of going up in smoke. Certainly, amplifier design (and effects pedals) have been advanced by abusing equipment or simulating the abuse. But it is not without risk.

In the OWNER'S MANUAL, below the block diagram, is a table with all the various input and output impedances and signal levels. I would study that carefully before I started randomly cramming plugs into holes.

Here's an idea: why not use an instrument cable to connect a single amp's EFFECTS SEND to that same amp's own INPUT! Start twirling the GAIN and MASTER knobs and see what kind of noise and smoke comes out.

I'll buy a beer for anyone who does that and makes a YouTube video of it!

@JakobT had a defective overdrive in his Rumble 100. Perhaps @TheBluePhoenix also has defective unit.

How would I know if the OD is defective in my 500 v3? I think mine is a bit too powerful. I have to set it at about 1 - 2 to get a nice tube like sound. I have to run the Level at about the same setting as Volume to keep the clean and the OD at the same volume level.
You know I like it, Linnin, but that is the only issue I have.
Using a Passive P select or a Squier CV P, same results.
I have no active basses other than my Mike Kelly and I haven't played it through the 500, just the 25.

Rumblers, what is the biggest gig you've played your Rumbles with no FOH support? (Also include which Rumble rig). Thanks.
Click to expand...
A semi outdoor (roof over, stage, enclosed, full wall one side, partial wall other side, open on the end, rated for an occupancy of 800, actual attendance about 200). No FOH for instruments. Two guitars and drummer. Fender P Select through 500 v3. Halfway through the first set I was asked to turn down.

I used a Fender Rumble v3 200W for this entire EP. Erase You and Nothing Is The Same feature its overdrive circuit, while Headstrong and Are You Lethal use a big muff pi/clean signal mix. Wanted to share because the amp absolutely MADE this record! It was a breeze in the studio thanks to its lightweight and its removable grill, which allowed us to mic nicely, as well as the XLR out and the excellent overdrive. Hope to one day upgrade to a head/cab unit, and was also wondering if anyone here knew anything about the circuitry for the overdrive. I'm trying to learn as much as I can about it, in the interest of understanding it and finding more overdrives like it. Thanks! Bo.

Hi, neighbor. I practice with one band in Arlington. Wow, that sounds great. Love what you get from your overdrive. Can you share your settings for that?

That sounds about right. Just crack the controls open slowly until you get the amount you want. Since there are no numbers we need to refer to 'o'clock' reference points. I take your 1-2 is really about 8 o'clock and just barely open. I use: 9; 9, 9 as a starting point - Gain; Drive, Level.

Right, I knew that. I really meant like 8 or 9. I just need to experiment more.
I guess Fender didn't put numbers on the dials to save money so they can sell them at a reasonable price. ;)

Hi Bo, if you'd like to join the club just let me know. Search this thread for Rumble Talk, and you will find a ton of informative inside intel. :thumbsup:

Nice! What band? Settings are as follows. Gain at noon. Drive all the way, Level at 1 o'clock. Bass at 5 o'clock, Low and High Mids at 2 o'clock, Treble at 4 o'clock.

Just curious as to why Fender didn't put at least one speakon connector on the back of their newer Rumble series amps. Speakon's are pretty much standard across the board now and it seems kinda counter productive to not include this feature in the redisigned Rumble bass heads.
