Cheers for the reply, i
Unfortunately i'm finding it to be loads quieter with solo octave, and even solo dry signal is far quieter than the pedal turned off. It is an ACA one, but I've tried it with 12v power supply, 9v power supply (with other pedals) and with a battery, none of which seems to make a difference. Luckily the seller is being really reasonable about it and has offered to refund. Thanks anyway man
