The WORST I have ever dealt with were the more recent (KMSR/KFCD) 990 studios. Oringinally, the control room consisted of an out of date, Studer board with a cracked screen, and the only place to get replacment parts was the other broken Studer that was ruined when an overzelous board op dumped grape soda on it. 900 then moved up in the world and bought a brand new, 25 channel Mackie production board (which started bleeding the channels after day one.) In the studio, only one of the CD players worked half the time, the other just make lovely flashing lights. We decorated it a christmas. That studio went through 3 live CD burners, 2 mini disc players, overheard light bulbs that would never be replaced, a wobbly confence table for the talent to sit at, and the studio went through 4 chairs in one month due to a rather robust board op who liked grape soda.
While these shortcommings can be blamed on the original KMSR engineer, the ownership gets the brunt of the blame for never spending money on the acutal studios. Come to think of it, they never spent money on payroll either.
