Dr. Wattson

X Series Available!

The Dr. Wattson is based on the preamp of the legendary early 70s version Hiwatt Dr103. The Dr. Wattson uses a pair of NOS Soviet 6N21B submini tubes in place of the 12AX7, allowing it to fit in a nice small box while keeping the killer tone you would expect from anything associated with Hiwatt.

The Dr. Wattson takes a standard 9V input, and can accept center negative or center positive inputs. It uses internal regulators to supply 6.3V to the tube heaters and 200V to the plates, giving it the richness you expect from a full high-voltage preamp.

Controls: Gain, Master, Bass, Mids, Treble

Like all Sushi Box FX pedals the Dr. Wattson is true bypass, hand-wired, and built with pride in Chicagoland, U.S.A.

Starting at $175

CURRENT DRAW NOTE: The Dr. Wattson uses vacuum tubes, which means it has current requirements higher than most pedals. During warm up it will try to pull around 1900mA on a 9V input, and when it has finished warming up it will pull about 770mA on a 9V input. You can probably get by with a 1000mA supply, but it will take longer to warm up. I recommend a 1500mA (or more) supply.
