Hello, Effects Fans!
This has been "on the way" for some time, and we're happy to finally announce the availability of our new Sweeper flanger module.
The Sweeper compares to the A/DA Flanger. The original A/DA Flanger was released in the 1970's. It has gone through several revisions and sometimes been out of production, but is again in production today. The circuit remained largely unchanged, although availability of different BBD analog delay chips forced minor changes to accommodate the different chips. Originally, Reticon chips were used, then various Panasonic BBDs, as can be found in the current models. Regardless of the model or BBD, the A/DA Flanger has retained its character and high quality through the years. Every version released has been excellent.
Despite its long history and high quality, the A/DA Flanger is probably not the best-known flanger, probably because it costs more than other popular flangers. But those that have spent the extra cash will find a unique wide sweep range and a rich set of controls that provide a wide variety of flanger and chorus-like tones. It also has another feature that sets it apart from the others - little to no "flanger noise". You know that extra swooshing sound most flangers (and phasers) produce which can be very noticeable in quiet passages and during rests. This circuit is engineered to remove nearly all of that without hacking out chunks of your signal along with it. There are other good flangers, but once you find a quiet flanger it can be difficult to go back...
The Sweeper stays pretty close to the original design. Of course, our power and switching are very different, but those don't have any audible impact on the sound. We use the MN3007 BBD, as was used in some versions of the pedal. The circuit has a number of controls, some of which were internal trimmers or external controls in different versions. We've made most of those external controls. There are still some internal trimmers, but those aren't meant to be adjusted after their initial calibration. We also offer an option to use an expression pedal. The pedal takes over the function of the Manual control and lets you control the sweep. We don't (yet) offer an expression pedal, but third party expression pedals will work. The Manual control is a "B10K" pot, or a "10K linear" pot. An expression pedal with a 10K linear pot makes a great direct replacement. Expression pedals with other values may only sound good in a portion of their range.
