I'm Austin and I run Guitarsav.com, I am here to tell you what I think.
First off, the website looks great! It is such a simple design which makes it more professional!
Secondly, I think you would get more business and it would suit you better if you changed your domain.
Yeah Guitarpedals.eu is great, but I fill like Warlordpedals.com would look even better since it has your company name in it.
Another thing I would Recommend is find a format where on the side you can choose the currency. I feel that guitar is a huge scene and it would be better if it would fit all countries/currencies.
Lastly for the layout look, if you look at the menu/navigation bar it says stuff like Guitar pedals Series. I would say to make it look better to capitalize all three of the words so it say "Guitar Pedals Series"
On another note, the pedals look great and I will be writing up a little blog post about your new company so I could post on my website!
