An improved device and method for the creation of acidic electrolyzed water is described. The device has an flow-through anode chamber and a static cathode chamber. The static cathode chamber contains a fixed amount of salt-containing electrolyte, which is renewed as needed. The flow rate of water through the anode is restricted to a range of about 5 to 40 ml per ampere of current passed through the electrode. Electrolyzed water flowing from the anode is diluted to obtain the desired concentration of hypochlorous acid, and is collected in a tank or other vessel. The electrolysis reaction is terminated when a preset amount of current has passed through the anode. Water circulation may be one pass or recycling. In a preferred embodiment, the membrane is anion-selective. Preferably, the membrane and the electrodes are integrated into a preassembled format that can be attached to the anode and cathode compartments via flanges or similar devices allowing quick replacement of an electrode assembly in an electrolyzer. The anion-permeable membrane can be protected by a protection membrane, in which are provided slits or other discontinuities to allow venting of gas.

For a stringed musical instrument of a type that includes guitars, electric bass guitars, and two-handed tapping instruments including the Chapman Stick ®, in departure from conventional frets inserted individually into slots or channels in a wooden fretboard/neck, a Railboard (TM) is made with frets that are precision-machined under CNC (computer numeric control) integral with the fretboard from a single block of rigid material such as aluminum. Optionally the instrument neck, whether body-attached or of through-neck construction, may also be integrated into the Railboard along with the fretted fingerboard. The fret-tips are initially machined with a sharp apex, then machine-dressed to form narrow flat fret-tip plateaus all aligned in a common plane, then selected frets are further precision machine-dressed to provide “relief” in a lower-pitched region of the fretboard for optimal “low action” playing characteristics, thus producing instruments of uniform quality in a cost-effective manner.
