What Pendulum Audio makes
The company's documented products are rack-style and module-format units rather than stompboxes:
| Product | Type | Notes |
|---|---|---|
| Quartet Tube Recording Channel | Tube recording channel | Made in USA4 |
| Quartet II Mercenary Edition | Tube recording channel | Made in USA3 |
| PL-2 Peak Limiter | Peak limiter | Made in USA2 |
| HZ-10SE Preamp System | Preamp system | Rack unit1 |
| SmartCord Preamp Module | Preamp module | Module format |
The Quartet II is one of the company's preamp products, and it is a unit many players arriving at this page will be comparing against other preamp pedals.
Warranty and repairs
Pendulum Audio warrants its units to the first purchaser to be free of manufacturing defects in materials and workmanship for one year from the date of purchase, and its obligation under the warranty is to provide parts and labor to remedy defects without charge132. The Quartet II manual adds that vacuum tubes and meter lights carry no warranty3.
The repair procedure is the same across the manuals:
- Contact Pendulum Audio, Inc. before shipping anything in. Return authorization must be obtained prior to shipment1324.
- Ship the unit, insured. The owner pays two-way shipping, and the manuals recommend UPS1.
- Pendulum Audio covers parts and labor for defects within the one-year period1.
The owner pays shipping both ways on a warranty repair, and return authorization is required before shipment. Contact the company at (908) 665-9333 or info@pendulumaudio.com first2.
For comparison, one year is a common warranty term among pedal makers: Saturnworks covers its pedals for one year against manufacturing defects5, while Wampler offers five years to the original purchaser with a dated sales receipt6.
