Bass Fuzzy Feeling

Whenever i plug it into the daisy chain my power supply switches off. Checked everything and thats fine. Can run it off a separate 9v supply and it works a treat but as soon as i daisy chain it with the rest of my pedals they all go off.

Not had this before. is it something obvious i've missed? Checked polarities, etc.

It uses PNP Ge tramsistors so requires a positive ground. So when you plug in a daisy chain power supply with negative ground it is shorted out. Needs a seperate power supply.

Thanks for the reply

Power supply still needs to be centre -ve though, yeah? Bit confused with the positive ground bit

Yes, centre negative.

The PNP transistors use a negative supply so the ground or 0V is more positive than the rail.
