Because it definitely is not for me. I couldn't use the BYOC tremolo because it clipped with my guitar, so I'm wondering if this is a systematic problem with all BYOC pedals or if the OD2 is just supposed to be like that.

Mosfet or Silicon? Cuz one is a lot cleaner than the other.

Are we talking about the boost or the overdrive? I thought the Mosfet and Silicon were for clipping for the overdrive section. I can check again, but I didn't think it made much difference when I switched between them with just the boost on.

We're talking apples & oranges here. When Yoni refers to MOSFET and silicon here, he's talking about the transistor that you used to build the boost section, outlined in green on the diagram on page 33 of the instructions, not the diodes or MOSFET's used in the clipping section (in red on that page). Depending on which transistor you chose to use--BS170 MOSFET or MPSA18 bipolar silicon, the character of the boost is altered. The MOSFET boost has a cleaner, sparklier sound, while the bipolar silicon gives more output and a bit of distortion of its own at higher gain settings. Also, depending on which transistor you chose, some of the other components in that section should be different, as described in the instructions.

BTW, any boost, no matter how "clean" (i.e. undistorted) its output, is potentially capable of driving an amp's front end into preamp distortion, depending on how it's set up. A lot of players use boosts for exactly that purpose. What's clean coming out of the boost doesn't necessarily mean it will be clean from the speaker.

That was how I was planning on using the boost, but it gets a really nasty sound that also seems to add some compression, so I tend to avoid it. I went with the silicon for that section, but I guess I could switch it to MOSFET. It sure was a pain getting everything in that case, though...

Yeah the silicon will make cause a nastier tone. I like it. I crank the gain on the overdrive side or even boost my fuzz into an even louder beast. I use the mosfet boost when I just need the signal louder like on my vibe or when i want some more highs to come.

Oh, ok. Faith in BYOC renewed :D Thanks for the help guys.
