If its not a typo, it doesn't make any sense... have you tried it recently? I think the result would be that you would not hear any sound at all. The signal chain is incorrect; the amp is not receiving any signal. I have three pedals. I hook them up normally. guitar in---out to pedal 2 in---out to pedal 3 in----out to amp in. Works fine. I think you must of had a unique pedal or something... it doesn't matter what the effect is... the normal signal flow is input to output. Any normal pedal that follows that will not work if you hook it up backwards.
