Mic pre in pedal form?

[A.David.MacKinnon]

I've started performing live drone and loop based ambient music. I'm playing guitar through a bunch of pedals and loopers (including a uher report L running tape loops) and want to add the option using my voice in the same chain.
I'm trying to track down a mic pre in a pedal format that will run off of my pedal board power. Super basic is fine. Not having a ton of gain is fine. I just need to get the mic up to passive guitar pickup levels.
Does anyone know if this kind of thing exists or am I going to have to roll my own?

My old Digitech JamMan looper has a mic input, but it fails to run on pedal power it uses it's own AC wart.

I think Electro Harmonix made something like that. Maybe called 12ay7. Joel Hamilton was into it for a while I think. You might be able to search and find it.

The jamman is decent, so is the EH 12AY7 if you can get it not to hum.

Last year I did a variation on the Hampton jfet, I can't find any completed pics on my phone buy here's a couple of in progress

I have a pigtronix key master that I’ve used for this. 18v power

If you don’t mind the size, you can probably find an older Line 6 floor board with a mic input for cheap, get a bunch of fx as a bonus

Get a passive lo-z to hi-z connector. If that's not enough gain, run it into a clean preamp pedal and then on from there. No need for a real mic pre, IMO. I will say that Scodiddly's Hamptone-based project from a couple years back could probably be set up to work on 9V--with 24V and a step-up transformer on the input, I get ca. 40dB of gain, so I would expect you could get decent levels with that circuit.

JHS Colourbox V2 is essentially a Neve with EQ that also has a mic input. Although powering a condenser may not be exactly possible without something inline?

[Nick Sevilla]

You could get an impedance matcher for a dynamic mic like a SM58, and run that into a guitar BOOSTER pedal, which should give you enough gain to run the signal down your pedalboard, and not need phantom power.

That should do the trick.

[The Scum]

The Pigtronix and Eventide are both very solid versions of this idea. So is the Radial Voco Loco (also 15VDC).

For a little, no frills mic pre, look at the Rolls MP13 - claims to work from 9V, tip negative!

TC Mic Mechanic has one as well -- https://www.sweetwater.com/store/detail ... mechanic-2

12AY7 is correct. It's in the same enclosure as the other tube guitar / bass pedals, but it has its own power supply and is a real mic preamp. I still have mine. Haven't used it in a while, but I love it. I've thought quite a few times about racking it.

Thanks all!
I had briefly debated trying to rig something with an altec 1588 octal mic preamp can. It seems like a lot of work though.

I am running a jam man at the end of my chain. Thanks for reminding me that it has mic in! I would like to have access to all the pedals before it with a mic though. And maybe not worry about switching between mic and 1/4" inputs and gain settings. I'll keep that idea in my back pocket though. It might be handy.

I have a xlr-1/4" hi-z/ low-z adapter and an mxr micro amp. I'll start with that and see if it does what I need.

The Boss RC-20 has a 1/4” mic input. Probably overkill unless you want to loop your vocals pre-fx (in which case a 2nd Jam Man would probably serve the same purpose).
