I am in the process of building their bee pre. Very impressed so far everything is laid out good and the instructions are phenomenal with lots of pictures. It's my second kit one I did from another manufacturer was brutal. Some parts didn't match the instructions and when you asked questions basically all he said was look at the schematic. I would definitely recommend bottle head for anyone as their first kit or who is nervous about DIY.
