The Signal Sleuth brings with it a whole new world of FM-stereo enjoyment. Whether it be Bach, rock, or current affairs, the Sleuth will expand your world of FM-stereo entertainment, bringing you more FM stations, with better clarity. You will experience more of the depth and realism that is being broadcast from stations with 'fine arts' quality, program signals. Put simply, the Signal Sleuth amplifies weak FM signals cleanly; attenuates strong, harsh signals without coloration; stabilizes FM antenna (and FM cable) signals;  separates interfering adjacent-station signals and reduces multipath problems. Along with establishing a clearer, crisper sound, a most important attribute of the Sleuth is its ability to establish and maintain a useable FM program signal level. In most cases, this will eliminate the annoying 'flip-flop' stereo-to-mono-to-stereo switching usually experienced with many FM tuners having non-variable, automatic 'blend' circuits. The Sleuth FM signal amplifier has already awakened many FM enthusiasts to the sweetness and depth available with a stronger FM signal.
