well it's got to be cheaper than using thermite on large phantom powered condenser
just be careful and not do anything like this at home:

it may void your warranty

This is really goddamn good, what exactly did you use to get that sound? Just the contact mic and pedals?

edit: disregard this, I am a complete idiot and just found you listed all your gear on the page. Sorry. :wall:

Ok, i take it back, cell phones... they're not so bad. My ultra critical shitty inner voice says all this crap when I'm in public and 9/10 people have their cell phones out and texting or whatever, about half while they're walking. (not saying that I'm never this ignorant prick, most definitely I am) And then moments like this captured which is better than Cloverfield. [(sorry for posting so much, i think my caffeine buzz is making me talk, I'm really silent, but i feel lonlinees and I'm procrastinating finalizing some trackes and I like this little community online because i don't really know anyone but i get a good feeling)]
If I ever stop posting for more than a year or so, then I died and I really liked you all. Until then, ignore this.

Made this for the drummer, 90% dollar store parts. Piezo is from a little window alarm, box from the craft section, spring for a door stop. The jack probably costs more than the rest of it. He wants to use it with a bunch of delay and reverb stuff.
I think trying to quantify music is one of the biggest wastes of time in the world, like discussing your favourite colour or deity or pizza topping. People should realise that and get on with their life.

Thinking of buying a pair of Korg CM-300 to avoid maintenance issues and improve reliability during performances. Also the clip seems useful for field recording situations.
how is the sounds of those things? is it's actually richer than that of the microphones I make myself using standard parts?

Not used those but used similar clip-on cheap plastic mics, they are OK. they have smaller mic elements than most DIY ones, but i've not noticed a lot of different between different sizes for noise purposes anyway

Most contact mics sound the same unless you get into proper expensive ones for amplifying classical instruments etc. This one is marketed as being a clip on tuner mix so it might actually not even be that amazing since its main use is just to get a guitar signal into a tuner, not an audio signal into a mixer/amp, so they might not have designed it to have a particular great frequency range. Probably fine tho and should last longer than £2 ebay chinese ones

A piezo preamp and a good object to actually amplify, and the contact mic well attached to it in the right position, is more important than the mic really

Yeah this is exactly what I was worried for. Since contact mics are so cheap to make maintenance issues could be resolved with making more mics. I was looking for access to richer sound, so I can record some more interesting field recordings with my zoom h2n. I wondered if korg were using higher grade materials or something. But you are right, finding something with a preamp would be better.
Still I first saw the korgs in this Otomo live https://www.youtube.com/watch?v=wNgPvVPGyf0 I saw. I found some more experimental live shows of underground artists that were using the cm-300, but I can't perceive if there's any actual difference in the effect. Still - I have some bad experience with ripping mics apart during shows and I wanted some more reliability. and the cm also looks portable compared to most string instrument mics I've found. Not that they are that big, but the cm looks so much slicker. Idk I think it's my lack of experience that is making me so indecisive. thanks for the help tho - it helped me make my mind a little

Field recordings with a contact mic?

If you are recording from air, a moderate priced condenser might work for you.

If you are actually in contact mic land, you might want to play with a piezo strip, rather than a piezo disk, and see if it works better for your needs.

I was thinking of using a contact mic as a auxiliary microphone for my zoom. Recording tremors from traffic, machinery, glass, doors, trash bins and so on. I haven't thought of using different crystal forms - that's actually a pretty great tip. The shipping from this site is insane, but I'll browse around the shops I get piezo disk from for cables, strips or other. thanks!

If you plan on using a contact mic with your zoom, I'm pretty sure you will need an external preamp. I have an H5 and it doesn't even support guitars if you don't plug them into an effect first (at least that's what their undetailed manual told me).

edit: if you don't want to build one, there is the Boss AD2 pedal that you can power with battery and the impedance adapter from Tritonaudio that functions with phantom power:

Strange. My H2n worked with all the diy mics i've build until now. The sound is okayish. That said, I've already thought about getting a preamp so I can up my onkyo game a little. I also thought that a preamp could replace a sound card in some ways. It can't increase the sampling rate, but it can clear up the signal and give me some control over tonal accents. At least this is how I understand it. I'm not a big gear guy actually.
Sadly, due to economic and teritorial reasons, online marketplaces are usually too expensive for me. On the other hand I browse non-stop local markets. Sorry they are not in english, but here are some of the options I've got in my watchlist
https://www.olx.bg/ad/bb-preamp-custom- ... 7yryf.html
https://www.olx.bg/ad/lampov-predusilva ... 7GIuG.html
https://www.olx.bg/ad/preamp-barcus-ber ... 7Behm.html

I think I like the last the most, because of the tremble and bass controls. I think I can really flesh out the sound of a sheet of metal with this.
I'm feel like I'm being too careful with all of this.

By the way, do you want a sample of the h2n?

those preamps might help / sound good somewhat but they are line or instrument level preamps so they still won't correctly correct the impedance of a contact mic as far as I know. aside from building one the cheapest option for a true piezo preamp is to get one of these ones for building into an acoustic guitar, and hack it into some kind of box. I used one and it worked well tho I since built a smaller DIY preamp. Advantage with these tho is that they have built in EQ -

https://www.gear4music.com/Guitar-and-B ... preamp/AV8

https://www.amazon.co.uk/dp/B00CGY2P0G/

- these are just quick google finds to give you an idea of the kind of thing, i'm not recommending these particular models or sellers

oh just found one on your local site :) no idea what kind of a price that is. you'd need to chop the wire and solder a socket on there for your own contact mic. you could save the weird thin one that comes with it, solder a jack onto that and use it as an optional contact mic too :)
https://www.olx.bg/ad/fishman-elektroni ... 3ad5d7362f

the input on these is a weird micro-jack for the thin under-bridge pickup they come with, you can very easily solder a 1/4" socket in place of that, or get/make an adaptor.

:D could be micing up a bridge or a wire fence in the wind or something? else yeah that's going to be a minimalist recording to say the least

or dispense with the mic entirely

And here I was thinking that it's actually better to get dedicated outerior preamps. Thanks! I already saw the one that you linked, but I thought that it' actually worse than those I linked you up to. This is around 30$, which isn't that much money here. I will search for some alternatives, but you are right - if I built it into a box and make the cable a bit longer it will be really nice to use. Thanks for all the tips! Even more this one has a extended eq options compared to the others I linked, which is exactly what I'm looking for. The fact that it uses a 9V battery will help me make it portable as well.
thanks for that - I'll check it soon!
