Pedala are un switch numit Headroom care dubleaza voltajul, inca nu am primit-o si nu am manualul, dar asta scrie pe site.
Deja numai inteleg, pe alt site am gasit asta:
Another important feature is the HEADROOM SWITCH. Set to the "HI" position, an internal electronic voltage doubler is activated – the Diablo runs on 18 Volts from a regular 9 V battery or power supply. The higher voltage gives more dynamic range, more headroom and tighter bass – just try it!
Precizez ca sunt nul la electronica deci habar nu am ce inseamna !
