Boost

Just finished putting this build together and initially had the wiring backwards for both gain and boost button. so LEDS off effect on and LEDS on effects off. Quick switch of the wiring and all good except the boost button now does nothing noticeable. when wiring was reversed could definitely hear and large boost when active, now notta. Any suggestions ?

So I've found the same problem with Boost. It doesn't work. The rest sounds great at least. Anybody knows how to fix it? It would be de puta madre!!!!
