I agree. I have built a version of the Pultec point to point and it was a royal PITA. I am working on a layout right now (maybe we can do a group buy later if there's enough interest). In an attempt to keep this a poor man's project I have come up with an outline of one switch PCB that, by suitable component changes, can be used for both the hi and lo sections. I have excluded the pots as that gives lots of flexibility in their choice and mounting and its only a dozen wires to solder up. Here is a pic of the layout as it stands - the board is 2.1 inches wide and 1.4 inches high so it should fit in a 1U rack if required. I have tracked in two capacitors for each frequency for maximum tweakability. The two resistors, R1 and R1 are only needed for the hi boost and cut and can be wire links or zero ohm resistors for the lo boost/cut. The terminals (pads really) T1 thru' T4 are the only external connections necessary. The only other component not on the PCB right now is the 56K resistor needed for the lo boost/cut. I am going to draw a version of the schematic using this PCB as building block so you can see how it would all wire together.
