Guitar Pedal – Balanced in to Low-Z unbalanced ==> HiZ to Balanced out

A client asked for a way to balance a guitar pedal so he could send and return Line Level to his guitar pedals.   He wanted a way to use his pedal collection as effect sends.  We came up with a modified Ward-Beck Systems POD-1.  The POD-1 offered op-amp gain adjustment trimmer pots so you are adjusting the gain of the balancing amplifiers.

The un-balanced output impedance is roughly 30Ω and the unbalanced Input Impedance is 47kΩ.  It’s a pretty safe assumption that mopst guitar effects can operate within these ranges.

You could also use this as a re-amp tool and a hyper-transparant Direct Inject box for keyboards and anything unbalanced.


XLR input Balanced +4dBu differential Receiver to an RCA connector to a 1/4″ TS jack that feeds the pedal then return to the opposite.
