The Wonderbar tremolo, also known as the Shift 2001, is a distinctive vibrato system introduced in the 1980s. Developed by the Japanese company Argus, it was later marketed by Washburn Guitars under the name “Wonderbar.” This innovative design allowed guitarists to install a tremolo, or whammy bar, without the need for extensive modifications to their instruments.
Design and Features
Unlike traditional tremolo systems that require body routing and utilize springs, the Wonderbar employs a torsion bar mechanism. This design enables a top-mounted installation, eliminating the need for rear cavity routing. The unit offers adjustable intonation, string height, and arm angle, providing versatility for various playing styles. Its all-metal roller bearings ensure smooth operation and help maintain tuning stability during use.
The Wonderbar’s unique design was patented to protect its innovative features. The patent details the torsion bar mechanism and the top-mount installation method, highlighting its advantages over traditional spring-based systems.
Popular Models
The Wonderbar was available in several configurations to accommodate different guitar types:
- Standard Model: Designed for most electric guitars, offering a straightforward installation process.
- Locking Version: Included a locking nut to enhance tuning stability during aggressive use.
- Fine-Tuning Model: Featured fine-tuners for precise pitch adjustments.
