Vision Octavia by Roger Mayer

The Vision Octavia by Roger Mayer is a guitar effects pedal designed with specific features and technical specifications. The pedal is an evolution of the original Octavia effect used by Jimi Hendrix and is now part of the Vision Series enclosure design. The pedal's front panel controls include:

1. DRIVE: Sets the gain of the stages before the equalizer section, adds sustain, and affects the feedforward action and gating threshold.
2. TONE: Adds a tone circuit between the drive and octave stages to control signal harmonics.
3. OUTPUT: Controls the final output level.

The Vision Octavia features multi-mode outputs with hard wire bypass or two buffered outputs. It has three outputs: a true hard wire output and two buffered outputs that can drive long cable lengths with no high frequency loss. The pedal also includes an LED to show the effect's status and a rapid battery change feature for easy battery replacement. It has exceptionally low current consumption, ensuring a battery life of more than 150 hours with alkaline type batteries. An external AC adapter can be used, and the pedal's ergonomic design makes it pedal board-friendly.

The pedal's dimensions are as follows:
- Width: 170mm
- Depth: 112mm
- Height: 57mm
- Weight: 618g with battery
