I have a Carvin BX1200 that I would like to have repaired and to have a few custom modifications done to it. It's currently not working properly and I have already had it repaired about a year ago - I prefer to have some non-Carvin parts put into it. I am looking for someone local in the Chicago area that might be able to help me. If there is someone else you recommend, please let me know. Any help is appreciated. I prefer someone who is familiar with Carvin bass heads or at least really good with solid state heads. Thanks.
