From the vendor
Loads of pedals run great at 18v, it gives you more headroom – but building in a chargepump after you’ve already built your board is a pain in the….
Our handy 3PDT daughterboard with 18V onboard chargepump solves that problem. It fits in a 1590B and up size case, takes standard 9V input and then converts that to 18v to feed your board, all whilst sorting out your standard 3PDT footswitch wiring…handy eh!
Note: make sure the caps on your board are 25V before you smash 18V into a 16V rated cap and it goes poooof.
