The "Manhattan style" is a very old method of circuit construction. It's especially popular among radio amateurs for high frequency circuits because it has a solid ground plane that helps to reduce interference and noise.
It's also a fun way to build simple discrete circuits. :)
To build Manhattan style you need a copperclad board. It only needs to be a one-sided copper layer. The first step is to make small cutouts in the copper for the component pads and cut the board to a good size (to fit the enclosure that you want to use). I use a bench drill with a circular drillbit to make small "islands" in the copper. Just be careful so you don't drill all the way through. It's a good idea to use a multimeter to check that all the pads are not conducting to the rest of the board (which will be connected to ground). Another common method that doesn't require a drill is to cut out small pieces of copperboard (from another piece of board) and glue them onto the main copperboard to serve as component mounting platforms.
I'm using a "diamond hole drill bit" like this one (the 8mm one).
SCHEMATIC TO LAYOUT
Before preparing the board, it's a good idea to make a sketch of the board layout. Converting a schematic to a Manhattan style layout is generally very easy since the layout will closely reflect the schematic in most cases. Here's to the right is an example of a circuit, the LPB1 booster - a very simple transistor amplifier.
The first thing you need to do is to identify and count all the common nodes (or "nets" as they are typically called in PCB software). This is how many pads we need to drill on the board. Don't count the ground connection, as it will be connected to the rest of the copperboard as the groundplane.
Parasit Studio originals
The Omfug is a gated and glitchy square wave one-knob fuzz. It's basically the preamp section of the Darkadiator (a discrete guitar synth) - a single gainstage followed by a schmitt trigger. I thought that the Omfug was a fitting name. A homage to the classic punk club CBGB's that was located in Manhattan... :)
I used very hot humbuckers. That's why the attack sounds so compressed.
Another one-knob fuzz. This is more of a ordinary fuzz loosely based on a fuzzface topology. It cleans up really well when turning your guitar volume down. I wanted to find a use for all those russian transistors that I have laying around so the signal path uses two germanium transistors. The rest of the circuit is a discrete voltage inverter, designed specifically for the manhattan style in mind so I could keep everything on the same board. You can play around with the values for the input and output capacitors for different bass response and thickness. The name is a homage to the band The Germs (because it's a germ-anium fuzz hehe...).
The discrete voltage inverter is not something I would recommend using for any other build style that can accomodate IC chips since an IC based voltage inverter will be far superiour in every way.
