Chances are you'll saw a standard-sized 45 mm x 45 mm piece (shown) in half.ĩ. A piece of perf board (perforated circuit board) at least 15 holes in width and seven in height. (Substitute a B10K if you can't find a C10K.) Schematics can look intimidating, but it doesn't take long to learn the basic symbols. Two 16 mm potentiometers ("pots"): A100K and C10K. (Not all will appear in the final pedal.)Ħ. (You'll only use one in the final pedal.)ĥ. (You'll only use two of these in the final pedal.)ģ. Get small-format caps rated between 50 and 100 volts, not the large-format caps used in amps and other AC-powered devices. These can be polyester film, "box style," or ceramic-they all sound the same in this circuit. (In the U.S., a complete set of parts should cost around $50.)ġ. The extra parts are quite inexpensive, so I recommend getting them all-you'll learn a lot. Part of the project involves auditioning multiple components to choose your favorites, so not everything in the list will appear in the final pedal. Here's your "bill of materials" (BOM)-the engineer's term for a parts list. Others you must order from a stompbox parts specialist. You can get some parts from any electronics supplier.
… plus an electric guitar, an amp, and two audio cables. Optional: a syringe-style de-soldering pump. Optional: a "helping hand" vise to hold components steady while soldering.ġ5. A small saw and vise for cutting perf board to size.ġ4. But even budget models should have the functions needed for this project: a voltmeter, an ohmmeter, and a continuity function (a beeper that sounds when you touch the test terminals to any two points that are linked electronically).ġ2. These have many functions, and the high-end ones can be quite complicated. "Auto-ranging" meters are the easiest to work with. (Long-handled luthiers wrenches are nice if you can afford them-plus you can use them for guitar repairs.)ġ1. Even in this simple circuit, small modifications can dramatically alter the effect's sound and responseġ0. (Most strippers have cutters, but you'll probably want a separate flush-edged tool for tight, close cuts) It's never too early to modify projects to better meet your musical needs and personal style. (You can make your own, but the prefab ones have metal tips that don't fray from repeated use.)ħ. (They make large-format ones, but most stompbox circuits are simple enough for a small board.)ĥ. A damp sponge to clean the soldering iron's tip.Ĥ. (Less toxic than the leaded kind, but still nasty.)ģ. Use a fine, narrow soldering iron tip-the best choice for small-format electronic work.)Ģ. A "soldering station" with a temperature control is a big plus. (Preferably 30 watts or more, but not a large gun-type iron. Ones marked "optional" are nice to have too.ġ. You'll need these tools to complete the project. The tools you need-plus a few that are nice to have.
