Title: Multiple circuits on one Road Rage?
Post by: jkokura on November 12, 2010, 08:10:13 PM
Hey,

Does anyone know if I can run multiple circuits off one Road Rage board? For instance, can I run a positive ground tonebender mk 2 (-9V road rage output) and a negative ground Big Muff (+9V output) together on one board?

Another option I know if is building the Tonebender Mk2 to run on Negative ground also, but I'm not sure if that's wise or not.

As a secondary question - I'm going to be building a road rage into a rangemaster to supply the rangemaster with positive ground from a negative ground supply. Is there any reason I shouldn't do this?

This should work fine in either case. Many pedals use positive and negative supply lines while using a common ground. You can always test your pos. ground circuits out with the neg. before loading in any expensive transistors. Just hook everything up, confirm you are getting the correct pos/neg voltages with your DMM. Then you can safely load your super duper $8 glass packed OC44 in :)
