hairball audio, lola pre amp issues

[cengle333]

Hi I have been building a lola mic pre amp and have gotten to the end of the main pcb installation. In the guide it says to test it out so that's exactly what I did. The led lights came on when I pushed the buttons but when I tried to connect a condensor, a 57 and a guitar, none of them worked or showed any signal. I went over all the steps and everything seems to be in place correctly but I did take note of a few things that I saw when I was putting the pcb together. One on the resistors brown and purple seem to be mixed up because when I use the website to calculate the colors purple can never be the last color but if I make it Brown then it adds up perfectly. That is a problem since it is clearly purple but after eliminating all the  other resistors I must assume they either sent the wrong ones or used the wrong paint. Then I also noticed some of the colors that were suppose to have a .01 tolerance, have a 1 % tolerance according to the color code. Lastly I noticed they said to ignore the slots at the top of the board labeled opt c and opt r if you're using jh 990's but mine came with je 990s so I am unsure if that means anything. Any advice helps, appreciate it!
