I still gig with my original '65 DLR and have been mic'ing it to the house mains. Open mics can cause their own problems so I'm hoping someone can offer a recommendation on how to tap into the speaker output and take a signal that could be padded down to feed a mixer without damaging the amp or degrading the quality/volume of the amp's internal speaker.
Is that possible? Or should I just be resolved to stay with mic'ing the amp?
Thanks!

If you plan to use still have the speaker connected while creating a line out level then parallel the speaker with two resistors........a 100 ohm resistor connected to the hot/tip in series with a 10 ohm resistor to ground/sleeve. Take the "line out" connection from the junction of the 100R and 10R resistors.
If you plan to not use the speaker then you will have to disconnect the speaker and rig up a wire to connect a properly rated 8R resistor. Repeat the above steps with resistor.

Thank you very much! Just so I'm clear I've attached a very crude sketch of what I believe you are recommending along with the DLR amplifier schematic. Have I understood your directions? Also, what wattage rating should the resistors be?
Thanks again.
Thanks again.

Your drawing looks to be correct. I would use 5 watt resistors for the value resistors I provided in my previous post (100R/10R). If you are using a DI between amp and soundboard then you can use higher value voltage dividing resistors like 1k/100 at a 1 watt rating.

Its worth noting that the internal speaker adds its own colouration to the sound: it is part of the instrument. There's no guarantee you'll like what goes out to the desk.
What sort of problems are you having with micing?
I've never had an issue, though I suppose if you're running the amp quietly with the desk gain cranked, that could get problematic.

I would use a Shure SM or Beta57 on a short stand, directly in front of the loudspeaker to preserve the Fender sound.
All DI connections must be isolated from the source and balanced, to avoid earth loop hum.

Thank you for your feedback and suggestions. I appreciate that the speaker adds it's own "color" to the final sound. I am using an AKG condenser that I'm happy with. I was looking for an optional alternate method to the desk. I have a couple of isolation transformers (and commercial DI's) that I'll try. If I end up with ground loop or RF hum I'll stick with the mic.
Thanks again.
Thanks again.
Many commercial DI boxes have 2 settings for the input level: "Line" which expects a Preamp Out (around 1 V RMS) and "Speaker" , which accepts around 20V RMS
All have balanced XLR out to feed the house mixer.
Best include a Speaker Simulator so sound is natural instead of buzzy ... which happens if you just tap speaker out without filtering it with the natural speaker/mic response.
This is a VERY good one, the Classic by which all others are rated:
Red Box | Hughes & Kettner

Thanks. My DI's have pads for input level but this RED BOX looks like the way to go. It appears you just put the Redbox between the amp speaker level and the speaker, pad it down by 25db, chose your "speaker" settings and connect to the desk. Very kool.
You put it between amp and speaker, the speaker always gets full power, because the In and the Out/Through jacks are simply in parallel; the 25dB pad applies only to the line out signal.
You will still need to use your mixer pad, because Red Box line out signal is Line level.
Many complain it's too Hot, but that's because they plug it in an XLR Mic input.
Any Pro mixer will handle that anyway, most simple all in one powered Box mixers will not.

As a thought, if you're set on DIing into the desk, you could bring your own insert box for that channel, which would have a fixed EQ of your choosing, to get the sound of the speaker back.
Its not gonna be exact, but it'll be closer than nothing at all, and much more flexible than the EQs on most desks. Even digital ones.
