My first Big Muff was returned to Thomann, it was not functioning properly. Thomann customer service was great, this was the first time I have had to return an item.
A replacement was sent very quickly. It's a monster! Delivers amazing Fuzz and sustain. Works nice alone, but better of drove by an OD pedal. I paired mine with a Vox Ice9.
Overall I have been left with a sour taste in my mouth, you would not expect a product thats made in the USA to be defective. Maybe I was just really unlucky. I have a EHX Big stone, and was planning on buying the EHX Pog2, thats an expensive pedal, I am now very worried about the quality of EHX products.
Without the quality issue I'd have rated 4-5 stars. And I will update this review as I have only had the new Big Muff back one day.
Once again, well done Thomann on handling my return so well, this is why Thomann is no.1 in Europe.
