Harley Benton PowerPlant Tuner

The pedal works great. It's very easy to see the display, so far I connected 3 other pedals on the 100mA (a Wah, a mini TS, and a Mooer Black Secret) and it does not generate hum or added noise.
Next pedal will be a Whammy DT and I will update the review after testing it.

Major downside, and the reason I cannot give it 5 stars is that it came with a VERY noisy adaptor. The power source injected a siren like noise which made playing unbearable.
Thomann sent me a replacement, but unfortunately the replacement had the same issue. It got solved it after buying a "Truetone 1 spot" at a local shop. No more hum, but cost me 20€ more.

I have this tuner pedal in my stage rig which covers my role as a bass player in one band and guitar in another. I did have issues with it at first but have now found a set up that works.

There is noise; by the bus load. This occurs when certain distortion pedals are in the signal chain. Not a problem I have had with any other pedals so I assume that this one is to blame - So why do I still use it? Well I like the look of the display and the fact that it distributes power saving space. My bass rig (in Drop D) has always been fine and I note the comments in other reviews about not registering correctly - never had it myself. Even when using a 5 string bass with a low B it registers.

For guitar I have had to compromise but again, once I found what worked the pedal consistently performed.

So what should you make of it?
If you are willing to persist with it then you have a very well made tuner with a great display. If you want to unbox, plug in and use then perhaps you should find something else. I will be keeping mine and will continue to play about with pedals until I work out what is causing all that noise!
