Looking to install a JJB 430-C, 4 transducer pickup system in a classical.
Steel string installation with bridge pin holes to locate transducers is not an issue, but what about when there are no bridge pins?

Catgut is an abbreviation of the word cattle gut. Gut strings are made from sheep or goat intestines, in the past even from horse, mule or donkey intestines.

Otherwise it could be from the word kitgut or kitstring. Kit meant fiddle, not kitten.

Does the classical have fan bracing? You might be able to use that for left to right placement. Measure the distance from the edge of the soundhole to the saddle, cut a scrap of wood to that length and (gently) clamp (or tape) it inside the guitar to locate the saddle position. Working blind through the soundhole is always fun!

Using mirrors place a piece of tape, masking tape that you can feel on the center brace the distance back from the sound hole that you want your transducers.

Wipe the bottom of the top on both sides of your tape with accelerator on a paper towel getting it on the underside of the top.

With one drop of superglue, medium on a single transducer reach inside and find your tape. Stick the thing next to that tape, hold for a count of ten and then look with the mirror to be sure it's acceptable. Exact placement is not the goal here but approximate placement is fine.

If your dot of medium CA was small enough you will get your finger back too....... ;)

I like to loop the cable once onto itself too to take up some slack on say a KK. I've never installed one of these that you have.

Next with each subsequent transducer repeat the steps except for wiping with accelerator just move quickly so the initial wiping is usable for all three or four transducers. I can always either feel the tape or the previous transducer and use that placement as a guide to stick the next transducer next to it.

Or, conversely use an LR Baggs Lyric classical and only have one small mic to stick between the fan braces with placement being not at all critical in my experience.

Hope this helps Buddy and Merry Christmas to ya too! :)

Thanks Trevor. Bit of serendipity here.
The "sheep pen" sort of idea came to me last night as I was dropping off.
I've already used something similar to position a Braggs Anthem internal mic on a steel string with narrow bridge plate. Located it with dowels up though the bridge pin holes.
