Hey, did you ever figure out more about this? I checked out your instagram and you’ve got some really cool videos on there!
I’ve got some pcbs of the conrad papers circuits coming, and I’m trying to wrap my head around what’s all possible with them. I’d love to be able to put a jack in the preamp and/or anti-preamp to get my guitar (or other sources) in there
I just tried to draw a schematic of the preamp circuit. I don’t know if it’s 100%, I’m really new to all this stuff. It’s here:
EDIT: attempted to model the circuit in a simulator. At this point I’ve gone over the connections a bunch so I’m fairly sure that everything is set up right in here and it can be used as a schemativ, but the simulation doesn’t seem to be amplifying the signal at all.
If anyone spots any issues, please let me know, I’ve spent way too much time on this hah http://tinyurl.com/yc96olcc
Do you or anyone happen to know where would be a good place to tap the guitar (ts input) into. I was thinking maybe a DPDT 2-way toggle switch to switch between piezo and guitar, but based on your instagram, you’re getting some really cool interactions between the two.
Really looking for any info (from anyone) that points me in the right direction of understanding this stuff more!
