Plate reverb is an artificial effect that utilizes a sheet of metal that vibrates sympathetically with a soundwave that hits it. The basic architecture of a plate reverb unit has a large, thin sheet of metal (nearly 6.5’x3’ in the case of the legendary EMT140) that has a transducer at one corner driving the sheet in much the same way as a speaker would, on the other end a pickup to capture the vibrations of the metal sheet, and a mechanical dampener that reduces the plate vibration. The reverb sonically stays out of the way of the dry path due to the minimal initial reflections and a full warm reverb that tapers smoothly fades out into a tail. In the studio, plate reverbs were routinely employed due to the way they added a natural ambience without interfering with the original program material… That and the fact that even though they were nearly 7 feet long and 4 feet tall, plate reverb units were a heck of a lot smaller than a giant room or hall when ambience was needed on recordings.
Plate reverb units were used on just about every instrument including vocals. Though they sound particularly great with electric guitar due to the minimal early reflections which keeps plate reverbs from sounding too “effecty” and obvious. The warm quality of the full-bodied reverb naturally tapering off compliments perfectly the voice and range of the guitar. The problem has been until now, the giant size made plate reverb units prohibitive to use on the road. We are proud to brag that the Talisman is 479.99% smaller than the leading plate reverb!
Catalinbread always felt something was amiss with so-called “plate reverb” settings on many products in the marketplace. They often simply sounded thin, metallic and crappy. It was almost as if the programmers said while tapping on a cookiesheet, “yeah I know what a metal sheet sounds like, I’ll program it to sound that way!” Their goal was to capture all the goodness of classic studio plate reverb by actually experiencing a maintained EMT140 at Jackpot Studios with recording engineer Larry Crane.
Because plate reverb was born in the studio, on the Talisman Catalinbread have included studio style sidechain effects that are routinely paired with plates. These controls are PRE DELAY, which delays the reverb by about 100mS. And HIGH PASS, which rolls off the low frequencies of the reverb. Both of these controls allow you to tune the reverb, in order to keep it from interfering with the dry signal.
