Harley Benton Rockplug Metal

I purchased both the Metal and the Classic Rock version of the HB Rockplug, and they compliment each other very well.

This metal version has a good variety of tones. With the gain knob, you can range from crunchy overdrive/fuzz all the way through filthy metal shredding distortion. There are virtually no cleans, but that's not why you buy this! The tone knob does a good job coloring the sound, and the volume keeps you from blowing your ears off.

The aux input makes it easy to connect to your phone/laptop in case you want to play along with a track in the same set of headphones (be aware though, the 1/8" male-to-male cable they provide is laughably short and not usable). The Rockplug comes with a USB cable for charging, which is much easier than always replacing batteries in some other brands' models.

The casing itself is plastic and not super sturdy. The on-off switch on mine is a bit funky and doesn't quite click into place, but for £11 I don't expect it to be perfect.

Absolutely worth the price! Great stuff HB!

I am using it when I'd like to practice after 11pm with high quality Bayerdynamics headphones.
With low gain setting I get quite nice tone so Idon't feel any frustration any harsh sounds

Pros:
* cost nothing
* sounds good
* good battery life
* line in (but... see cons)

Cons:
* I don't like the way when line in input is NOT parallel with headphones output. So no matter how you position the unit one cable is always sticking out somehow
* line in sounds strange. I have almost feeling like line in is before CAB sim so output music or beats sounds strange. I also have problem to align volume

Verdict: if you are not planning to use line in often this may be great unit for you

This is a great starting point for amplugs - it has a good high-gain sound, and the USB charging makes it practical.

Unfortunately the USB charging port has become dislodged on mine and I've not gotten it open to fix it. I mainly used it on a desk plugged into a pedal for recording, so it wasn't from particular manhandling or anything either.

As I say, if your expectations are set according to price and don't expect it to last forever, it's a good starting point for trying out a high-gain amp sound before investing in something more solid (and more expensive).
