WAISTBAND OR FANNYPACK: These tend to put out a lot of sound for their size, especially directly in front of the speaker. They are compact and fairly light weight (typically about 1 lb. to 11⁄4 lb) and can be very convenient for those who are comfortable wearing a belt. (If you wear an over blouse, sweater or shirt, the amplifier can be worn under it. The sound should come through with no trouble as long as the cloth is not extremely thick or dense). These amplifiers can be worn to the side or back if preferred - and also can be unbuckled and set on a table, hung on a chair back, etc., which might be needed to avoid feedback when sitting at a table if the chair has a back and arms. It is important to consider the size, weight and positioning and hand/arm capabilities of the wearer compared to the exact shape of the amplifier and the position and design of off/on switches and controls. This type of amplifier may vary a little in length and depth, may have knobs that stick up, may be difficult to position comfortably for larger people. Users must have reasonable dexterity to unbuckle and place it on a table or hang it over a chair. If hung, the speaker will point toward the floor. It will probably have the volume control and off/on switch in one knob or dial, so that turning it on will require adjusting the volume - you will not be able to leave it set at a preadjusted level that you know you prefer - but you can mark the unit with a bit of nail polish or felt tip pen so you can quickly turn to your most common setting.
