If you like the EH Holy Grail but with slightly smoother tones and a way lower price tag, you will love this pedal.

Of course, this pedal is significantly cheaper than many of its competitors (Holy Grail, Digitech Hardwire, Tonebug,etc.)

I returned it to Amazon for a full refund and then bought an EHX Holy Grail Nano.

So far, the Holy Grail is flawless and the sound quality is better than the Biyang even before the machine gun noise started.

Using these settings you can go from electro harmonix holy grail to fender spring reverb

Sure it's no Holy-Grail... but come on

I had an ElectroHarmonix Holy Grail pedal for several years that I sold in order to get something different

The Holy Grail was huge (takes up a lot of space on the pedal board), requires its own power supply (can't use the OneSpot daisy chain), and there isn't much opportunity to tweak the sound

I own the holier grail.
