I just got an Analogman Sundial and they recommend the use of the cheap non alkaline batteries you would find in a $1 store as they are supposed work better with these pedals . My concern is using cheap batteries and possable leakage that might cause damage to the circuit board and components . Has anyone found that the use of these cheap batteries makes much of a difference in how the Sundial/sunface performs ? Not doubting your reasons for this Mike , just wondering why cheapo "time bomb" batteries in a nice electronic device . My other question is...if you are using a power supply do you still leave a battery in the pedal . Any reason that you do ? I'm using a power supply so I would rather remove the battery to eliminate the chance of an acid leak....and yes I have seen the top brand batteries leak too .
