dying 9 volt battery simulator voltage sag

Custom built in Minneapolis, MN using new parts and circuit components to simulate a dying 9 volt battery. Enclosed in a cast aluminum 2 inch by 2 inch Hammond 1590 LB enclosure. Made in small batches and hand labeled in a style reminiscent of my favorite punk records as a teenager. Simply connect your power supply to this (Boss-style "barrel" connector) and connect another power cable (included!) to your analog effects pedal of choice (note: these do not 'play well' with digital effects). Adjust the knob to deliver a range of 9 volts to about 6 or 7 volts of power to your pedal. DOES NOT DAMAGE YOUR PEDAL! Custom enclosure color and knobs available for an additional charge upon request. Price includes free domestic USPS shipping! Choose your enclosure finish and knob at checkout. Includes box, instruction manual, standard 2.1mm power cable with right angle barrel connectors and Alchemy Audio 'mystery' goodies!
