someone has managed to steal / remove accidentally a knob off my svt-4-pro!!! i only ever have the case front off when it's being played - by me! and i sure as **** wouldn't put the case front back on if there was a knob missing! my question - and i'd hope this doesn't contravene the 'no sale ads' thing - is does anyone got a 'spare' plastic svt pro knob they'd be willing to sell me? thanks! edit: fliptops do not have the pro series knobs.
