Scumvibe lures / Whats that noise?

[spork]

I recently scored 5 Scumvibe blade style lures from evilbay. $23 for 5, delivered, I thought that was a pretty reasonable price and I was keen to give them a try.
Now I know they wouldn't usually be considered a trolling lure, but I'll troll pretty much anything I have tied on between spots, and I had one of these tied on the other day as I though a strong vibration might get a hit in the muddy water I was fishing. (It didn't)

Anyhow, I'm pedaling along in my own little world enjoying the scenery and serenity - and wondering what the bloody "humming / buzzing" sound is. It's intermittent, sometimes louder, sometimes softer, sometimes absent. The wind? No, sound level not corresponding to wind strength at all. Must be some sort of farm machinery off in the distance. But it doesn't sound far away. If I had an electric pump on my 'yak I'd think it was running on and off and perhaps had a bearing / bush on the way out. Only electronics I have are the sounder and the battery powered white light, which is turned off. Sounder is functioning normally.

This must have gone on for over an hour before the penny dropped. The scumvibe was sending it's high frequency pulse alont the braid to the rod, which was making the buzzing sound when it was in the ram-tube holder! Obviously when I was holding the rod it was quiet, also when in the "milkcrate bullhorn" it was silent. My speed through the water affected the frequency and volume.

So - I didn't catch any fish on it (yet), but these cheap lures sure have an awesome action and I'm sure they will catch fish, both in the salt and the fresh.

I bought some on their "Deep Diving Blades"...absolute rubbish They don't vibrate and they helicopter when dropped to the bottom. I have a bloke on Cheapo'bay that I buy some small blades off from time to time, also fluorocarbon line (so bloody cheap), that does some "quality" cheap ones. I think I threw the Scumvibe ones across the river when I was last there.

I bought some Kamikazi blades too, they work well but the only thing I can manage to catch on them is bloody catfish

I bought a pack of five scumvibes vibes last year. Changed out the woeful hooks and trebles for a single 1/O lure hook. I mostly troll them but do occasionally cast and retrieve. I have caught a heap of fish on them, very strong vibration (as the initial post suggests). I have even caught fish deadsticking. Blades are pretty simple lures (when done correctly). At 20 for five, add a few more dollars for rings and singles and I think that they are a pretty good lure. They work for me.

I have wondered if the amplification of lure vibration transmitted through your rod and hull produces an attractant or deterrent effect. It might not be quite low enough in frequency to have the same effect as a witchdoctor or similar teaser, but you'd think if the vibration of a lure attracts predators, it would only bring them in from further away.
