Have 2 older bass heads that don't have preamp out. And it really sucks. I use them as a monitor then usually have a female to 2 male TRS splitter, but this is getting old. Is there anyway I could still a hole in the back of my head and install a preamp out? :3 thanks!
Probably, but you would have to be a lot smarter than me about that sort of thing to pull it off diy. Other thing you could do is a speaker level DI type box. Probably about the same cost as having a tech instal a line out.
