laughingstock -> preamp into preamp (Oct. 7 2017 8:37:01)

So I'm having an LR Baggs Dual Source put into one of my guitars. Should be pretty straight forward. I have another guitar that I'd like to electrify and use for gigs. It has a cut-away and is good for Gypsy King like jams that I've been sitting in on with a group that only does THAT. Not my thing but it can be fun. Anyhow, it comes with a "hexagonic" pickup. I bought a Barcus Beeze IV pre-amp since it seemed to have everything I want (on-board, tuner and it accepts 2 sources). I'm currently looking for a good internal mic as a second source. Some mics have preamps. I heard that plugging a preamp into a preamp can cause preoblems. Anybody have experience with this and does anybody have a good recommendation for an internal mic?

Hi
I figure ultimately once your pickup is going into an amp or mixer it's being feed via another preamp
I've been using a fishman presys system (onboard) on my classical guitar- blended into an irig stage - into a Boss AD-2 (preamp) - guess that's a chain of three preamps before hitting the mixer ( getting the gain structures to work together is key to getting it to work )
If anything I noticed the sound is more 'compressed' - nothing else of concern
Which seems to help in some ways
I actually kind of like it but very 'electric' or treated sound - good for the Latin/Samba/Tango groups I work in from time to time
Maybe someone here is more technically minded but sound wise, to my ear, no real problems just a more 'compressed' tone
Phasing options on your system can also help

Good internal mic systems I've used
1 mini flex dual mic ( top pick )
2 bartlett mic pro
3 if you can locate an early b band clamp mic ( think they superseded these with transducers )

The irig stage is also good but kind of cheaply made so not sure how long mine will last

Hope that helps

Interesting. Thank you for your response. What do you mean by "getting the gain structures to work together is key to getting it to work"? Also if all three components (on-board preamp, USP and mic) use batteries, and different ones at that, does that mean I'll have to use 3 different batteries or can the other systems feed off the battery on the pre-amp?

Yes you can plug a guitar with an onboard preamp/pickup into another preamp, and indeed as many as you like before you plug into your PA/amp (what Alval describes).

But if you want to fit an internal mic wired directly into your Barcus Breeze dual source onboard preamp (which is what I think you mean) then you will have to consult your manual to see what is compatible in terms of things like impedance and whether the mic you want to fit requires phantom power, whether your preamp supplies this. ... and yes I suspect you would hit problems if the mic itself has some kind of preamp built in.

Good miniature internal condenser mics for guitar: Baggs, K&K, Barlett.
