Harley Benton TrueTone T-20

I needed something to connect my soprano ukulele to the computer (for recording), and I realized this might be the cheapest way to do it, if I didn't want to use any external microphones.

The pickup is very easy to place (using the accompanying sticky blue-tac-like paste), and does the job as you'd expect. For the ukulele, I realize the optimal placement is NOT under the bridge, as acoustic guitar users suggest, but right below the sound hole.

Two IMPORTANT things to consider:
1) You'll need some sort of preamp. I plugged it to my Zoom G1X, and it works flawlessly (plus, I got some cool effects).
2) Be VERY careful with feedback. I stupidly turned my guitar amp toward myself while trying to play. The pickup... picks up sound, which above a certain volume can cause some massive feedback. Turn the speaker the other way around, lower the volume, or use headphones.

Other than that, not much to add. It's not professional-grade, but it definitely does the job.

I bought this this thing to capture the acoustic sound of a semi hollow bass guitar. It requires a preamp to get a decent signal.

The build feels solid: the cable is thick, the jack socket seems sturdy and holds the guitar cable very well, no fears of the cable unplugging.
The sound is very thin and detailed which is to be expected from a piezo pickup, especially on bass. The only downside is that it's difficult to set up correctly and requires some experimentation to get a nice tone. This may be due to my specific use, but you'll get a lot of unwanted noise and clicks when touching the wooden casing or the cable even slightly. I'd still like to try this thing out on a drum shell.

Either way, for the price and build quality, I recommend this item. It does its job, but requires a little bit of experimenting and patience to get a decent result.

I wouldnt use it on a full scale guitar, but for smaller guitalele style guitars, this gives a very round and full sound. Personally I am still fan of undersaddle piezos but this thing gives you much more full tone and it is loud. You dont need a preamp but you should boost trebles with EQ on your amp. I imagine on a full scale guitar this can get too loud, and boomy and can start feedback, but for "not so loud" guitars this is very good.
