Montarbo Sinfhoton Highly ModifiedVerified

From the post

Well I said that I would post a layout with a bunch of modifications to the Montarbo Sinfhoton based on what I've read people have already done. So without further a due.

Notes:

• Removing the 100k resistor that's in series with D1 & D2 will increase the amount of fuzz, so you can lower it for more fuzz, raise it for less fuzz, or put it on a switch for 2 different settings. Hell, you can take and have 3 different settings using different combo of resistors.

• The "Focus" switch, by putting a cap to ground at the input increases the compression of the fuzz and can provide a subtle boost in output.

• The gain control I explained previously, but apparently putting a pot in series with the 22k or 47k resistor to ground gives a fuzz control. Johnk had used a 25k Linear pot, and raised the resistors value to 180k.

• Notice I used the "Later Version" to make the modified layout, this is because from reading a lot of people preferred the 2uF caps being raised to 10uF like the later version. BTW, you can use 2.2uF I just wrote 2uF because that was in the original schematic.

• As noted earlier, you may want to play with the 10k resistors to the transistor Collectors to set the bias right,

• As far as transistors go it seems higher gain transistors, >500hfe, people seemed to prefer, but I didn't read a lot about how lower transistors sounded. To me this looks like a really stripped down and modified Big Muff, essentially just the clipping stages, I would think some of the transistor tricks for the Big Muff may work out here, but no idea.
