SA9+ 40 Watt Head
SA9+ 40 Watt Head
The SA9+ is an evolution of the award winning DB7/ DB9/SA9.
This high-headroom amp 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:
-The SA9+ has a newly designed power transformer with additional taps.
-Additional power supply components in the SA9+ are used to convert and fine tune certain voltages used in the preamp.
- A Solid State rectifier circuit developed specifically for the "+" model.
Why this matters...
-Almost ZERO 60 cycle hum is generated by the amp.
-Notes emerge from a black (silent) background allowing for very subtle nuances and colors to be recognized.
-Much smoother and relaxed tone.
-Effortless and instant power makes for more dynamic playing. Rewards the right hand (and sometimes the left).
-Due to the new rectifier design, reliability is even greater than before.
Musicians who own these us them for...
-Both clean and heavily affected electric guitar
-Moderate volume, electric and upright bass
-Amplifying classical nylon string guitars
-Amplifying steel string acoustic guitars
Specs and features of note:
-Chassis is made of 1/8" (!) folded and welded aluminum then powder coated and screened.
-A 10 turn pot with locking dial is located just to the left of the tubes. This combined with the tip jacks (1 for each power tube) located on the back, make user bias and tube changes safe, fast and easy.
-All internal wiring connections made using a Litz coated, oxygen free copper wire of extreme purity. Unlike generic "cloth covered" wire, it will not absorb airborne moisture, oxidize and/or degrade the signal over time. Using this wire requires special tools and means that EVERY wire needs to be cut to length and tinned with a 900 degree solder pot. A laborious and time consuming process but the resulting improvement to the sound is stunning!
-The custom power, output and choke transformers have all been developed over our decades long relationship with Mercury Magnetics. They feature custom winds and lots of iron for reduced "sag", a tight and transparent low end and silky highs.
-Specific components are cryogenically treated to aid in their transparency.
