Don’t get me wrong, IRs have drastically improved the sound of piezo pickups live, but for me it’s just not there yet. Also, as the piezo loses some frequencies, sometimes you have to apply some harmonic distortion to bring them back in a more natural way, if you did that with just eq it wouldn’t sound as good.

With IR’s there’s always one note that sounds horrible because that frequency has been hyped to match the eq curve. In some ways it’s the same as an amp, depending on the intensity of the notes it drives more the soundboard and changes the timbre. And that’s not the way a guitar changes frequencies and dynamics, it’s much more variable and nuanced. I’ve used them before, but in the end, an impulse response is more like a static image of the whole sound and it applies it evenly to everything you feed into it. Thanks Chalky but the problem is not which IR to choose, but the limits of that technology. Is this possible? Is there a reason why it shouldn’t work? The user would just choose on the quad cortex menu the pickup he’s using and instantly it would sound like a studio recording. In fact it could be done with different brands of pickups and instruments (not just guitar, but also violin, cello…) creating a lot of flexibility. I don’t know if it’s possible, but if it was, then it could change the live sound possibilites for acoustic instruments. This way, it could apply the harmonic distorsion, eq and compression to match the real sound fo the guitar. Then run the capture process, but instead of comparing the clean vs amp signals, it would compare the piezo version versus the one recorded with the microphones.

Then install a vibration speaker, on the soundboard, those that make their sound by vibrating a surface.

The method would be setting up an acoustic guitar in a studio room, recorded both with the piezo and well placed quality microphones. The basic idea would be to capture “acoustic guitar profiles” so instead of sounding like a quacky piezo they would sound like the original instrument. I’ve been thinking about it for a long time and I think I’ve come up with a method to do this and it could be a great way to improve the sound of piezo pickups, but I don’t know if it’s possible.
