Weeell, I ended up going the route of stainless steel. I kept it at the full 4x10 sheet size, figuring it couldn't hurt. I was really hoping to find full hard steel, but ended up only being able to find tempered, so it's a little more malleable. I also couldn't find 28ga and went with 26ga. I don't ...

Yeah. I was noticing that at high amplitudes, the signal seemed to peak, except it was audible acoustically through the plate. I'm thinking I shouldn't have had a washer directly against the plate and should use rubber washers. Well, I have the rubber washers, but in the process of trying to remove ...

Yeah, I was going to do that when I remembered a problem I was encountering. I think one of the screws is vibrating against the plate (the one that attaches the driver), and I botched up unscrewing it. In short, does anyone have any bright ideas for removing a screw that's in a smooth, threaded cyli...

Now that I'm back for a week, someone wanna tell me how to make an IR and I'll post that up here for examination? I know it has something to do with sending a Dirac delta signal and... Burst of pink noise, right? How long, volume, etc? I'll try to take a picture of it as well, but the space is kinda...

I'm unfortunately going to be gone for most of the summer, so I won't have much time to experiment. I'd love to learn how, but in the current noisy state I'm not sure how good an impulse response I'd be able to get. It's really frustrating, because it sounds so good coming off of the plate in the op...

http://web.mit.edu/mrmiller/Public/Plate-reverb.aif Dry, mix, then wet. I figured out some more weird stuff going on. It turns out the preamp is picking up a lot of the radio signals--not quite sure why, and only when it's on the vacuum tube setting. Equally odd, with the standard mic plugged in, it...

Mine is heavily tensioned, though it's hard to say exactly how much. It's got triangles of steel welded onto all 4 corners, on both sides, then the holes are drilled through that. It's tensioned using threaded-bolt things, so you have a screw that goes through the hole in the plate and the hole in t...

haha, the ghetto plate sounds pretty awesome. And I may look into those turntable pickups... sound really interesting. I actually figured out my problem which was really stupid on my account, and now have only one major source of noise to abolish. I was running phantom power through the mic because ...

I was doing a single take recording using microphone-speaker feedback for an electronic music class and caught a bit of cell phone interference, unfortunately... though once it goes through the echo unit it's a little more pleasant. Start at 3:58 and listen for about 30 seconds... not going to subje...

The woman who runs it was very helpful and discussed the benefits of the various varities with me. She's very nice.

I'm basically dealing with an identical setup to yours. I'm using the Ghost as well, and originally had a home-made pickup that I put together from a piezo I ripped out of a Radioshack buzzer. I found it didn't really do the plate justice--that is, the plate in the open air sounded significantly bet...

Yes and no. I decided that the contact mic I was using was to blame for shoddy sound quality, so I'm waiting on one not made by me to come in the mail. It's unfortunately been a rather busy semester at school for me and I haven't had much time to fiddle around in the studio. But I'm itching to play ...

Not tonight, but I'll be in the studio tomorrow so I'll grab the tracks then hopefully. I'm swamped with schoolwork currently, but I'll try to have it up tomorrow night for comparison.

Put everything together. Haven't really tightened any bolts accurately or anything, and my contact mic has a lot of noise, and I don't have a power amp. But other than that, I think it sounds pretty good. The trail's also rather long, so I should probably figure out some way to cut the reverb time. ...

Well, things are starting into motion at last--I'm getting all the steel on Tuesday and will hopefully get it all welded at the MIT Machine Shop soon thereafter. Then the tensioning, and sometime in there making the contact mics. I'll have more to update after all that, I guess.
