Sounds quite interesting with my soprano uke fed through in the piezo settings then adding Drambo to shift the signal down an octave. Mix the two via wet and dry and add some saturation for taste. This is never going to sound exactly like a real acoustic guitar because the notes are much shorter and have a much different timbre but it still provides interesting instrument sounds.

When used with Acoustic Guitar, the purpose of this plugin is to make the piezo pickup or built in mic sound more natural.

I was thinking that when you plug your uke in, your purpose was to make the piezo pickup on the uke sound like the natural acoustic uke. Is that not what you are going for? Or are you saying you want the plugin to make your uke sound like an acoustic guitar?

I'm just exploring what it sounds like and what it can add to my methods. It does give a more natural sound to the uke when I don't do any further prrocessing, although it tends to "boom" a bit in the mid-range when I don't change the EQ. But further to that I was curious whether it could provide a passable imitation of an acoustic guitar when pitch shifted etc.. It can but the pitch, tone and volume envelopes are different to an acoustic guitar, as you know, so it sounds quite different to a guitar at the same time as occupying a similar space.

Ok I see. Thank you. I will work on making an input preset appropriate for making the piezo sound like an acoustic uke.

Cool. One thing to note is that this recording was my soprano uke. I tried recording the tenor with a stick on piezo but ran into noise problems. I can try again later if you think it might be useful?

What is the stick for?

Edit: I see now. Stick-on piezo is worth trying if you can get it to stop making noise for the recording. My first guitar had a stick on piezo. It sounded quite bad. But it would be interesting to see if we can improve it.

Yes, sorry, I meant stick-on piezo. Have used it before upstairs with a different recorder so will check whether I can record it later.

The Uke preset is in the latest test version.

Thanks @Blue_Mangoo i will check it out later.

@Blue_Mangoo , would this potentially work being fed with an unprocessed feed from GeoShred? I.e. no effect chain, no amp from GS?

I added two new presets for GeoShred acoustic instruments in the latest update. Here is a video demo:

Will give it a try with my ukulele later

Hm... I didn't test it with a uke. If it doesn't work for you, I would really like to have a recording of you strumming open chords recorded dry straight from the piezo pickup so we can make a custom profile for that.

I have a peculiar case too. A CGB guitar with a single coil pickup. The only profile that seems to work is the “electric piezo” one. ¿Should I send a recording?.
I love vintage clean so I’m excited about this.

With the cgb it seems like every preset makes it sound darker and more muffled. Granted the cgb is not bright to start with. I’m curious if this is a general approach to make the acoustic simulation… since an electric is brighter or has more high end than an acoustic, a general approach might be to reduce high end… Which doesn’t work well with a cgb (tuned low GDG) which is not bright sounding.

What is a cgb guitar? (CiGar Box?)

You are right in how you understand what the input type selection part of the plugin is doing: it’s just compensating the EQ, boosting where the input is weak and cutting where it is too strong. It’s not complicated, but we spent days tweaking each of the profiles to make them sound as good as they can. If your guitar sounds too dark when you use this plugin, it’s because your guitar is darker than the ones we have here. Please send us a recording of you strumming open chords like a beginner-style guitarist; no effects, just clean and straight into the iPad. We will try to come up with a better profile for your guitar.

Yes it’s a cigar guitar box!.
Where do we send the audio files?. I thought it’d be through TestFlight program but it only seems to allow screenshots, not audio files.
Cheers!

Your Cigar box input profile is in the latest version of the app. You can test it on testflight now. I recommend you enable the hiss suppressor when you run it.

Here is a demo video:

Thanks for sending us that recording.

Sweet!! 🙌👏👏👏
That hiss reducer is gonna be really useful!.

Thanks @Blue_Mangoo for the GeoShred presets. Don’t have a real guitar to compare against but sound good to me. Also controls all now saving correctly across AUM sessions. Many thanks.

Thanks for the suggestion. That was a great idea to use it with Geo.

When we do presets for guitars we can only get close and hope that our customers have a guitar with similar pickups, but with GeoShred, every one of us is working with exactly the same sounds, so an app like this one can guarantee that you hear exactly what we heard when we were designing it; it's really a perfect use case for this kind of app.

@Blue_Mangoo One of my piezo'd instruments is prone to mains hum (50hz in UK, is it 60 in the US?)

I can add in extra EQ to cancel the hum but I wondered whether users might find it valuable to have a kill switch for these frequencies?

@Blue_Mangoo It’s a good start on the piezo patches but too aggressive in the reduction in the mids IMHO. It sounds like there’s a blanket on the tone. Video here:

This uses an LR Baggs anthem pickup in my beloved Seagull spruce top acoustic. Just the piezo pickup.

@lukesleepwalker I used the recording in your video to make a new acoustic piezo input profile, called acoustic piezo 4 in the latest version of the app on testflight.

Hey thanks! I’m away from that guitar for a few days but will check it out when I’m back.

50 / 60 hz hum isn’t just a sine wave at 50 or 60 hz. It has an entire harmonic series, so you get 50,100,150,200,…etc. It can be filtered out if it’s not too loud but it requires a special filter that I haven’t got in my filter toolbox yet. It’s a good thing to have so I will make a note to work on designing one for later. Maybe we will release a separate plugin for it.

For now, you might try using an app called brusfri: https://apps.apple.com/us/app/brusfri/id1289165912

Looking forward to hearing it with my real guitars but I’ll buy it just for this!
