The Schroeder Amplification SA9+ Amplifier Head is an evolution of the award-winning DB7/ DB9/SA9.
This high-headroom musical instrument amplifier was originally designed with Nels Cline and Wilco. Known for its clean sustain, chime, and clarity, it rewards players who have a dynamic touch. Basically what you put in is what you get out...
Sonically the SA9 and the SA9+ are very similar and share the same control layout and functionality. The differences between the SA9 and SA9+ versions are that the Schroeder Amplification SA9+ Amplifier Head has a newly designed power transformer with additional taps. Also, additional power supply components in the SA9+ are used to convert and fine-tune certain voltages used in the preamp. I have also developed a Solid State rectifier circuit developed specifically for the "+" model.
The results are immediately noticeable. Almost ZERO 60 cycle hum is generated by the amp. Notes emerge from a black or silent background, allowing for very subtle nuances and colors to be recognized while we experience a much smoother and relaxed tone. Effortless and instant power makes for a more dynamically rewarding playing experience, satisfying on all levels. Due to the new rectifier design, reliability is even greater than before.
