hi all been lurking here for a while getting more and more interested in home building, the limits of my stompbox mods so far is modifying my dunlop cry baby  until it no longer works( will sort soon hehe).  :icon_redface:my stupid question is, i have an old storm line booster(pre amp) that only runs of 9v battery. could i hook up a power supply direct to the battery leads as long as +ve and-ve are the right way, and how would i go about fitting an led to it??any answers would be greatly appreciated, cheers chris

LED would connect the same way as always, and yes, although you'll probably want some decoupling.
