Excessive noise question

[chrisg_75]

my pedal chain is

Guitar > polytune > Whammy 5 > RMC10 wah > Dunlop Univibe (older large one) > if 6 was 9 fuzz > vs xo dual drive > tubesreamer > flashback x 4 > hot rod deville amp.

All pedals powered by Pedal power 2 plus.

My issue is the excessive noise for the drive pedals. I play a strat so yes the single coil noise I get. I put the fuzz on and with no guitar volume it is noisy. I unplug guitar and go straight into the chain into the I put of the fuzz and through rest of the chain and the noise is greatly reduced.

I plug guitar into the input of the univibe and the noise returns.

Is that something normal ?... doesn’t seem like it should be and is really annoying me.

Thanks for any help.
