Title: Boneyard power supply section
Post by: brianhujung on August 11, 2011, 11:38:33 PM
Hello,

Is there any different approach on bipolar power supply in boneyard power supply section?
Can I use positive & negative voltage regulator (7809 & 7909) on this circuit without affecting the sounds of this pedal?
or maybe using 555?
It's difficult to find the charge pump IC on my place..  :-[


Thank you.

ya, if you wanna go through the trouble of putting together that circuit. just make sure you connect to the correct pins.

you also need a transformer to get J1 and J3 connection, so there's more to this circuit than what's on the diagram.

I think the stock Boneyard sounds really really good running at +9v/-9v. Has anyone tried it at +12/-12v? Is there any difference? I think this circuit will be permanent on my pedalboard so if running it at higher voltage is even slightly better, I would go ahead and build a small pcb to get the voltage up.
