Boss SD-1W Waza Craft — Premium Analog Overdrive Pedal

The Boss SD-1W Waza Craft Super Overdrive re-engineers the classic SD-1 circuit with a redesigned discrete amplifier topology. Made in Japan, it preserves the iconic mid-hump character while lowering the noise floor. A Standard/Custom toggle adds a fatter voicing for lead work. The Boss SD-1W Waza Craft is the right choice for guitarists who want one pedal to cover both rhythm crunch and solo boost duties.

Two Voicings in One Pedal — Standard and Custom

What separates this pedal from the standard SD-1 is the Custom mode, which adds a healthy bass boost and extra gain. Both modes share the same Level, Tone, and Drive knobs and remain highly responsive to picking dynamics. The discrete all-analog circuit uses hand-selected components chosen by the BOSS team in Japan.

Signal Flow and Power Specifications

The Boss SD-1W runs on 9 V and draws 15 mA, making it friendly to multi-pedal boards powered from a single PSA-series adaptor or a 9 V battery.

• Nominal Level: -20 dBu — matches standard guitar pickup outputs.
• Input Impedance: 1 M ohm — preserves high-frequency detail from passive pickups.
• Output Impedance: 1 k ohm — drives long cable runs without signal loss.
• Current Draw: 15 mA at 9 V — low enough to share a daisy-chain supply.
• Battery life reaches Approx. 42 hours on a single alkaline cell.

Controls, Connectors, and Physical Layout

The control surface keeps the original SD-1 layout and adds a Mode switch for instant voicing changes.

• Controls: Level, Tone, Drive, Standard/Custom — three-knob tone shaping plus a two-position voicing toggle.
• Inputs/Outputs: Mono 1/4-inch (6.35 mm) — single-cable integration into standard pedalboards.
• The chassis measures 73 mm W × 129 mm D × 59 mm H — standard BOSS compact footprint.
• Weight: 430 g — light enough for a fly rig.
