Rothwell Audio Products Stompjuice


Rothwell Audio Products

The Stompjuice is a professional quality 9 volt power supply for guitar effects pedals. It will supply up to 600mA (enough to power several digital pedals - notorious for flattening batteries in no time) and can be operated from 115V or 230V mains by selecting the appropriate position of the internal switch. The 9 volt output is fully regulated and is transformer isolated for the best performance. It's true that switch mode power supplies, as often used to power computer and other equipment, can be very small and light whilst still delivering high current, but the problems associated with the high frequency noise that they can radiate make them less than ideal for use with guitar effects on stage. What professional guitarists really need is a good linear regulated power supply built to be robust and reliable enough to use on stage, with no noise on the DC output, and that can be securely mounted to a pedal board. The Stompjuice comes complete with detachable IEC mains cable and six detachable DC output leads and is fully regulated for hum-free performance. Construction is very heavy duty so as to withstand the rigors of life on stage under a musician's feet and a spare fuse is housed within the unit for emergencies.
