FV500 expression Pedal

[Groundy]

I am considering getting an expression pedal for my BR800, do I need low impedance  or high..........Alex

I have read that if your pedal is first in the chain which is the recommended position then it should be
high impedance.

The expression pedal don't go in the signal-chain. It just controls the effect on the BR800. According to the manual it seems like you can use either:

Use only the specified expression pedal (Roland
EV-5, BOSS FV-500L/FV-500H; sold separately).
By connecting any other expression pedals, you risk
causing malfunction and/or damage to the unit.
