check out this vid of Megan Lovell playing the Beard Road-a-phonic.
It gives you three examples of three great pu’s. It might help you decide on one type or the other, or even combine them as Paul Beard does on this guitar

The Fishman Nashville pickup is still the  state of the art, and most of us run it through either the Jerry Douglas Aura pedal or the Fishman Aura Spectrum DI. I think the consensus is that the Douglas pedal has superior microphone images compared to the Spectrum. There are other units aside from the Aura pedals to use in conjunction with the Nashville pickup. ToneDexter by Audio Sprockets is one, and a newer option is the L.R. Baggs Voiceprint - Rob Ickes has been using this one in the past year or more. 

Without using the various pedals to enhance the sound of the pickup, one will hear the dreaded piezo pickup "quack." 

But the whole setup gets expensive. Ideally the spider should be replaced with the Beard Adjustable spider or the Schoonover Modular spider. These do the best job of good contact for sound transfer between the pickup inserts and the spider, very important. Though there have been successful installation of the Nashville into regular #14 spiders and other brands as well. 

Back to the expense - you have to ask yourself if it's worth it to go through all of this for an F-60. The whole setup could cost as much as that Dobro is worth. 

A simpler and much less expensive solution is the Krivo Resophonic pickup. They go for a bout $250 these days. A surface mounted humbucker that is placed on the guitar top under the strings and is attached with putty, so it's easily removed. The cable sort of hangs off the side of the dobro. 

The Krivo sounds a little "lap steelish" because it is after all a magnetic pickup, but it's the closest I've heard to the real thing after the Fishman setup.  And most of the audience probably wouldn't notice the difference. Google the Krivo website, there are sound samples on there of the reso pickup. As an aside, the Krivo doesn't really sound any better when run through something like the Aura pedal, but it can sound closer to a true dobro sound with the ToneDexter but again, the costs start adding up.

And speaking of Fishman, you definitely want to avoid the "Classic pickup" or what  we refer to as the "donut" pickup that attaches to the tension screw underneath the cone inside of the guitar. It's terrible - I fought with one of years.

Check out the Search function here with the magnifying glass icon on the left side of your screen. The hangout is now over 17 years old. Type in "pickups" and you'll find enough reading  to last you an  afternoon. 

There are also a variety of mini microphones with brackets that attach to the guitar, check those out as well. Pluses and minuses depending on the unit. 

No idea if running any of this stuff into a Quilter Tone Block is a good idea, but being a solid state amp as are most acoustic guitar amps maybe it works fine. I think you can also run the Tone Block direct to the board and not even use a speaker.

 

Along with watching the Megan Lovell video as suggested earlier by Brooks, check out this excellent demo of Mike Witcher running  the Nashville pickup through the Douglas pedal. He's playing a Schoonover guitar (excellent!) and it has the Schoonover Modular spider which I have in my "A" game reso, a Clinesmith.

The answer to me would depend on how much of a “purist” you are in terms of preserving as much Dobro tone character as possible while amplified.

If you are primarily a steel player, you may be completely satisfied with popping a Krivo on your Dobro and running it through the same rig as your steel. As a magnetic pickup, it will be feedback resistant.

I tried the Krivo and indeed it was too lap steel-ish for me. Too much sustain, not enough dynamics, etc. Others use the same setup and love it.

If you’re more of a purist, the Fishman N’ville / JD Aura combo as Mark described is sort of the standard. (I tried a Spectrum instead of a JD Aura, and I couldn’t coax anything as good as the JD Aura. YMMV).

If you’re really a purist, look at a clip on mic like the AT Pro 35 (budget), ATM 350 (better but slightly more expensive), or DPA 4099 (premium). Be aware you need to take precautions against feedback for any condenser mic, and even then, it likely will not work for particularly loud stage environments (drummers, loud monitors…).

Personally I blend a Fishman Nashville/JD Aura with an ATM 350 and it has worked like a champ. That’s likely overkill for your use case.

Mark is right, cost / benefit is a major consideration for you. As would be convenience if you are switching back and forth with steel guitar on stage.

Krivo might be your best option if the sound samples are deemed “good enough” for your ears. Good luck!

All great suggestions....I know Beard Road O Phonic guitar sounds great, pricey, still doable.

I like the clips of the Nashville PU thru the Aura pedal...

I'm not big on lap steel sound so I guess I'll keep on the look out for a higher end, used guitar with on board's or search for a someone fairly local to that can do the setup on my current bro.

On my '29 National tricone I use a Meyers pickup, which is a little microphone on a gooseneck with a suction cup, because I don't want to drill holes in the guitar. On my '32 National Style O, I use a K&K mini on the biscuit and put it through a Tonedexter and it sounds very much like the acoustic instrument through a mic. The new Tonedexter is pretty pricy though. However, I use the Tonedexter with all my guitars, so the cost is spread around, but it still comes out of your pocket.

One thing that often gets left out of threads when players are asking for advice on pickups is the typical playing scenario. Maybe 90% of the time.

Solo? Small acoustic only group? Small venue or a larger building? Mixed acoustic/electric band that can get loud, often including a drummer?

The latter is what I ran into quite a bit when I decided to go for a Fishman Nashville pickup run through the Jerry Douglas Aura pedal  a number of years ago in my main guitar, a Clinesmith.  I had been fighting a losing battle with a setup combining the Fishman "donut" pickup with a microphone. Feedback before getting sufficient volume, sound "bleeding," etc. 

I've never owned for example a Myers, and though they seem to provide good sound, over the years on this forum some players have complained that in loud situations they were having a difficult time with feedback so they gave up on the unit in those situations. 

As always, your mileage may vary.

Good News....I just commissioned Mr. Dan Brooks to add a Fishman Nashville pup, Quarterman Cone and Setup my current F60 Dobro (Gibson).
I had a great visit with Dan and was privileged to view 2 of his B&B Resonator builds. Folks his Reso's are cannons....
Now to order my Jerry Douglas Aura pedal to compliment my newly, overhauled F60.
Thanks to all who contributed to my post!
