Garbage Disposal Air Switch Kit Dual Outlet Sink Top Waste Disposal Long Stainless Steel Brush Nickel On/Off Air Button Food and Waste Disposals Part by Etoolcity

Upgrade Version: We redefined the air switch, made of real stainless steel, never worry fade away and fall off, more elasticity and flexiable.
Two Power Module Installation Methods: You can use screws to fix the power module part, or use strong nano-markless hook sticker to attach directly to the wall. Both ways are very strong.
Unique Dual Outlet Design: The 'B' outlet using for the garbage disposal is controlled by the air button.
The 'A' outlet using for other devices like hot water dispenser or dishwasher is directly powered.
Easy To Installe Air Button: Just drill a not less then 1-1/4 diameter hole in the sink, counter-top or front of the sink cabinet, place the rubber gasket between the push button and the top of the sink counter. Tighten the plastic nut under the sink counter to ensure a watertight seal.

Audio-Technica Instrument Condenser Microphone (ATM350U)

you want it – the gooseneck won’t flop around no matter how aggressively you move the instrument as you play. The microphone’s cardioid polar pattern isolates the instrument by reducing side and rear pickup, and the switchable 80 Hz high-pass filter on the in-line power module helps control undesired low-frequency noise. The system also includes an AT8468 violin mount with hook-and-loop fastener and a protective carrying case. Features: Low-profile mic design for minimum visibility Crisp, clear, well-balanced microphone response, even at high SPLs Cardioid polar pattern reduces pickup of sounds from the sides and rear, improving isolation of desired sound source Unmount universal clip-on mount attaches securely to instrument bell and provides excellent shock resistance for the microphone Rugged Unmount 5" gooseneck rigidly holds its shape, keeping microphone accurately positioned even during aggressive play In-line power module is equipped with a switchable 80 Hz high-pass filter to control undesired ambient noise Interchangeable elements available for hyper cardioid and omnidirectional polar patterns Included violin mount with hook-and-loop fastener provides an additional mounting option Specifications: Element: Fixed-charge back plate, p....
