content: Hey, uh, this is to continue the side discussion, on a TOY REVERB mechanism, in original form of a big microphone.Today, I bought a stand-alone pickup, having controls for the VOLUME, and TONE. It uses the magnetic fluctuations of the set of 6 strings, usually, although I'm (attempting) to configure it, for the sensing of a single source, that being a metal spring, that carries audio fluctuations that happen along its length. This is, also, how Fender Music has their reverb effect added to the original, 'dry' instrument sounds.

content: Not to claim any sort of huge originality here, as there have been maybe more serious REVERB microphones, way back in 1970's audio gear. Which is how I grabbed the ideas so easily. The main special effects reverbs work by sending, or casting audio into one (spring) end, and meanwhile extracting or receiving the effects sounds, at the far end.A little thought and you can also realize this same mechanical principal also explains the classic REVERBERATION PLATE, (I.E.or 'Plate Reverb'). That variation is a recording studio device, likely weighing a lot. Many Plate Reverbs use a huge metal plate, 6 ft. by 8 ft. and some 1 " inch thick! (That's approx 2 by 3 meters size).Pro studios apply various audio tone compensation, to get the overall sound that they want / need. Of course nearly all can be done by DSP means, in today's very fast and cheap digital devices.The producers likely know about Plate Reverb characteristics, like much faster speed of sound (inside metal plate) thus reducing reverb 'dwell' perceptions. A good, tough HAMMER blow might be used in Hollywood Sci-fi sound effects, IDK (don't know).-Rick

content: Yes, some videos will proceed to play, while others go to the 'APP UPDATE' required screen. Part of the frustration is having to repeat the situation, to numerous people...as if I have to be some White Knight, defending 'justice' and having to describe the conditions, as if any lack of access is my own fault / responsibility.I obtained that response dialog from another member, here, who 'declined' to be part of that, partial gaslighting. It's a real problem, that some don't see. Google never really does any 'reach-out' type of information sharing, (or we could be clear, what's up with latest feature added to the existing features, searching).Ask Google tech support, because you waste your time just simply 'declaring' you don't see it (some videos do play, without mandating an APP update. Traditionally, the entity making changes, to policies or whatever is the GO TO agency to get informed.What's changed ? Why do I (we) absolutely have to upgrade our APP, and by way of obtaining AN ACCOUNT?THATS what I mean, by expecting that entity to give some meaningful explanation. Perhaps things would run fine, without forcing updates, in lack of any of explanation. I've never even heard of a Google 'Technical Advisory' being published,....have you ?

I mean, the latest photos are showing up as 1000 mb' size.(Almost more of an interesting point, than my original material, here, lol).So I've posted so the mechanical aspects of the acoustic guitar MODs are clear, at the guitar neck's String NUT, where my half-assed spacing job appears a little sloppy. No problem; got my Dremel tool and a bright light and sharp eye.Corrections needed:Mechanical dimensions, of the thicker string slots need some expansion, for more normal (looking) settling of the FIVE string set, into the five 'nut' slots. That's obvious and first to do.But then also, with a proper careful project attitude, I could observe at least two places, where I've not cut the seating slot exactly, as measured (by my NEW calipers, yippee!), and very very carefully doing some tiny delicate slot expansion, for a tiny bit of horizontal adjustment, of string vs. the whole set of five positions.This kind of zero-in focus is part of the enjoyment, working with mechanical aspects, of technology. As far as ultimate performance, that's not so clear, as I've been attempting to use a fairly thick weed trimming line, for musical sound, (but the thickest string is a bit dull sounding.)

content: Quote from: RJSV on August 15, 2025, 03:02:03 amI used to build guitars...Yes, that spacing is very wonky. Easiest way to get it right:- get a cheap dividers.- mark the lower and upper strings where they belong- adjust the dividers so they can walk the distance perfectly...and then just mark the pointsUnless you're into equal spacingbetweenthe strings....which makes absolutely no sense to anyone but people selling fancy rulers that do such things. Certainly makes no sense to the player.When you have that layed out, you might give just a HAIR more room between the lower strings for vibrato and bending. But just a hair. No more than that.

content: Gawd, yet another complication ! I'm not aware that guitar players use anything but equally spaced strings, but I suppose that could make some sense,...to space the thick strings with more room.It was fun, to contemplate the spacing, by re-use of the two most outer slots, and creating a new center slot. The standard 6-string configuration I dumped, in favor of less congested play action, (and besides the std. does not have a 'center' string.Played mostly like a BASS, at a one fifth interval down, some 3 finger chords work good, (as in the cool sounds we've all heard, from listening to Beatles' Come Together.). Playing fifths and similar rock - blues low end.I could have tried 6 strings, on the modified Ovation model guitar, but five feels really. nice and plenty of tone personality (except for that dead-beat thick line, at 0.098 inches).

As a player, I can't imagine why you would ever want that. It would be like playing on a piano where the bass keys are huge, and they get smaller and smaller as you get to the higher registers.

content: Wonky, yes, as you can observe, that high end string has more space, than the other four. Modification will be to 'continue' the slot cutting on one wall, thus creating a deeper but horizontally shifted 'trench'.I can always supplement, in that trouble spot, by the placing of an additional string guide (post), to move or reinforce that one string over, as needed. If things get really dicey, on that one placement, I can always 'Go Standard's by taking guitar to get a shop-fitted new NUT customized.

content: looking at your acoustic guitarfor a basic acoustic guitar pickup use a piezo transducer at the guitar bridge end of the instrument.for a DIY electronics project you may like to make a piezo transducer preamplifier circuit that will work with any audio amplifier that you have.lots of video of homemade acoustic guitar piezo pickup electronics projects on youtube. if your only playing with a cheap toy musical instrument.My opinion- I started a automatic guitar project back in 2015based on the metal spring reverberation concept. or mechanical reverb tankmy concept was to use input driver transducers that are low impedance hand wound coils & use high impedance guitar pickups for the outputs.but in a re-design as an automatic guitar is not played by human hands, the wire (electric guitar strings) spacing can be increased.so individual spaced pickups with hand wound low impedance coils can be used .amplification for the driver transducers is just a 4watt audio amplifier. one per channl 6 in all and the 6 pickups.if low impedance coils are used , tape head preamplifier circuit will do.with a plug board for all the ins & outs as used in old school analog modular synthesizers.to play the musical instrument the guitar strings need to be modulated by an audio input . pulse or tones.guitar fretboard jack screw assemblys needed more work. with the automatic guitar unit looking like a Japanese Koto.fretboard has movable bridges (kotoji) set on jack screw assemblys moved by 6x 24 volt DC motors at the end of unit.originally my 2015 concept was to have 10 strings 6 for lead & 4 for bass on a wide solid timber block.but used a timber door threshold as the base so was limited to only 6 strings.arduino coding the software was taking a lot of time. this way more complicated than expected.my automatic guitar reverberation project was mothballed in 2020.

content: So @jonovid: was your "automatic guitar" going to be fretted by moveable "bridges" (you mentioned koto bridges) moved by linear actuators along the length of the string, and depressed to fret that note?Pretty ambitious. And that would be alotof motion, especially for fast playing passages. Interesting, though.I guess the alternative would be to have lots (dozens) of solenoids depressing individual stops against the string at each fret position. I wonder if that would be doable? Would eliminate all that linear motion.

And then I also feel like there's fun and value in doing things that are kind of whacky and stupid, for no other reason than it's fun, and whatever. I have my own stupid things I do for fun...not engineering kind of work, but other stuff.Most forumites (myself included) do well not to take stuff so personally, and some should maybe do better at softening their approach. This is supposed to be fun.If you were my kids, I'd make you two go hug each other right now. I'll bet if you guys met up for beers, you'd have a good conversation.

A pickup generally has magnets, for putting a static field around the guitar strings, along with a sensing coil.That pickup, in my case here, will hopefully work also, to sense the spring vibrating.As described previously, this stuff will be mounted inside my acoustic guitar, and will sense the nylon / plastic 'strings' .I've got fingers crossed but still need time to hook things up, life and neighbors taking my time, on regular compound duties: Shopping for residents, taking care of cats, etc.

Here, the method of sensing will be acoustic, directed into the spring that works in the toy reverb microphone.Next, assuming testing works, I'll be placing the toy microphone into the body of my acoustic with the weed trimmer strings. Result is intended to be a full-sounding baritone guitar, tuned approx. a musical 'fifth' lower than standard guitars use.

I'm just getting into that quality question, on the pickups, and one of the videos the narrator was very negative, and the pickup with preamplifier that he reviewed did not produce any audible effects, even through a loud amp. To check on that, all I have to do, is drag out my (wheeled) amp with 10 inch sub-woofer, drag out the Orange amp, and start attempting noises.However, (domestic bliss and all), and I mention the following only because it's so silly:Dog comes over to my chair every 37 seconds, to poke wet nose into my business, interrupting the puppy, who wants play 'bitey' and wants to clean my eye socket (continuous). Course that interrupts my relative, asking if I want 'crumpets', every 29 seconds. (You know the drill).CHAIR rocks horribly (best chair in house), while 'some birds (Hawaiian Doves) regularly come inside the kitchen, dive-bombing anybody's face, that gets in their way.
