Output impedance of sound hole Mags?

[Mbroady]

OK, Mentioned this before but I'm switching gears.

I'm looking to put together a bit of a Frankenstein 3 source set up (Just because we can) and the preamp I'm using has a 1 ohm input impedance for each channel.
The Mag, (rather then a UST) will cover the low end and will be combined with a mic and SBT.
So, to high of an output impedance from the pickup/mag, and I loose some low end.

Hence my question.

Any thoughts and/or suggestions (other then it's over kill, which I already know )

I don’t know for certain, but I recall looking for these details before and settling on the 1 ohm setting in my HX Stomp fwiw to use with my Black Angel mag. Not 100% how I came to that but I know I played around with it some.

I have a K&K also but it requires a lot more eq attention than the mag (and other various preferences between one and the other).

I like to combine the Black Angel with dpa mic as is possible though, I haven’t found an IR solution to use with the K&K that I like nearly as much as the internal mic + pickup combo.

One Ohm input? Is that a mis-type?

1M ohm

More of an omission then a typo . Thanks for pointing it out

[Mbroady]

Decided to go with a k&K Double helix. The preamp is a K&K so it makes sense that they would be compatible

Will post sample when all is said and done

Output impedance of a passive pickup varies depending on frequency. Generally, magnetic pickups have a lower output impedance range than piezo pickups (i.e., USTs and most SBTs).

Yes. Magnetic pickup output impedance is at least 1000 times lower than piezoelectric pickup output impedance (both UST's and SBT's). This is one reason why you don't just simply combine them on an output jack. You need active electronics in a dual (or more) source device.

I use a Baggs MixPro preamp to combine a magnetic pickup and an SBT on my archtop.
