Most of the pedals out there are not the same inside. They might have 95% of the same circuitry as the original, well known, famous, pedal. But some of the components will be different as well. The pedal will do what is expected of it, but the sound will be a little different too. Now, you all remember my BYOC Classic Overdrive pedal that I built, right? I talked the guys at BYOC and they assured me, absolutely guaranteed me, that the Classic Overdrive is virtually identical the famous Ibanez Tube Screamer, with exactly the same components - even the same IC chip, JRC4558D!! The only thing is, YOU have to solder it all together, piece by piece, using all the capacitors, resistors, diodes, etc... and pray you don't mess it up! Do I own an Ibanez Tube Screamer? Uh... Well... Technically, yes and no. I have the authentic components of one, all custom built by me, but just housed in a generic, rectangle stomp box enclosure. AND IT WORKS GREAT!! Put my BYOC Classic Overdrive up against a real Ibanez Tube Screamer from a music store, and they are virtually identical tone wise.
