From the post
I haven't done a layout for a while and as this is a nice simple one I (as I like them) I thought I'd add this to the collection. After doing it I noticed that HamishR has added a layout to the forum and that one is verified. But I thought I'd still add this to the main blog. I did it with the components on the switches though to keep the board more simple though so you can just choose the one you prefer.
You can see HamishR's layout here:

Info about the original:
The Friedman Golden Pearl is a transparent, lower gain overdrive pedal designed to push already overdriven amps into seductive saturation. This versatile pedal can also be used into a clean amp to achieve that elusive semi-broken up tone.
Designed to please the ultimate tone connoisseur, the responsive controls, along with the three position high-frequency cut switch, let you custom tailor the pedal to your amp.
Even greater refinement is available via the tri-mode clipping mode switch, which provides LED, diode, or no clipping voice options. Built in the USA, and designed to withstand decades of abuse, the Golden Pearl is a must have pedal for any guitar player.
