Several versions has been made of this great sounding overdrive and this version is called "Boost+.The layout is based on the schematic at FSB but I took the liberty to do some changes that could be useful.
First, the J FETs remains to be unknown so I added a Bias trimpot to be able to use several types of J Fets.
Second, the internal 9v/18v switch is now panel mounted.
Third, Level+ control is now external....simply because there are too many trimpots already!
All the trimpots (except for the Bias) is on the edge of the board for the option to build an 11 knob overdribe...:-p.
