The Ginger is a bass guitar distortion stompbox that is adapted from the Ampeg SB-12 Portaflex. It is designed to capture the sound of the vintage tube amp and provide high gain with accurate frequency response. The circuit has been adjusted to reduce noise and improve overall frequency response, and each stage has clipping diodes to avoid hard clipping. The low-pass filter at the output has also been upgraded for better attenuation of frequencies outside the original speaker range.

Key Features:
– Adapted from the Ampeg SB-12 Portaflex for bass guitar distortion
– High gain with accurate frequency response
– Scaled down tonestack impedance to reduce noise
– Clipping diodes at each stage to avoid hard clipping
– Improved low-pass filter for better attenuation of frequencies outside the original speaker range

The Ginger is not only suitable for bass guitar, but also provides excellent overdrive for a guitar. The flexible tone controls allow for fine-tuning, making it versatile for different playing styles and preferences. The drain voltage of Q1 and Q2 can be adjusted close to 6.0V using the corresponding trimpot, and once the optimum resistor value is determined, the trimpots can be replaced with fixed resistors for better noise performance.
