Phaser Guitar Pedal: A phaser guitar pedal is a guitar effect that splits a signal, send one path through the circuit cleanly and shifts the phase of the second. The two signals are then mixed back together and when out of phase, cancel each other out. This creates a s…
Stumbled across the schematic for this compressor and couldn't find a layout for it. So I drew it up. This follows the original red box version, not the black box reissue. It's an optical compressor and apparently fairly subtle. I couldn't find any info on the vactrol used in the original–sockets are your friend. Should be an easy fit in a 1590B.
PT2399 is a chip built in echo effect circuit, built some parts, basic guitar effects. DIY experimenters also a good choice.
Here's a simple one that should fit nicely in a 1590a. EQD's take on the Electra Distortion circuit. Instead of having a pot coming off the end of the circuit, the volume is controlled by a pot coming off the emitter of the 2N3904. It's really more of a gain control than volume and if you wanted to, you could add a master volume control coming off the output. Who doesn't love more knobs, right?
The way to create the "Reverb" effect can be divided into two types: mechanical and electronic, depending on the operation principle. The first and at the same
I've seen a few designs out there that starve a tube filament to maintain a low voltage and still provide nice results. The Matsumin Valvecaster is one of them. For those afraid to work with tubes due to high voltage (cue Electric Six, "Danger! High Voltage!"), this keeps the power at safer levels. It also allows a 9v battery to be used (or 12V) but will consume them fairly quickly... so an AC adapter is recommended. The design is nice and simple, and for beginning builders it's not too hard to follow the circuit visually. There are a couple of variations floating around, so if you're looking at multiple schematics or diagrams, be aware that they aren't all the same. Other builders have created their own unique pedals based on this design, but the values of the parts are different, so again, be aware ;) Matsumin Valvecaster schematic from hgamps My favorite diagram/illustration was from David Smith. The input and output jacks are included as well as the 3PDT switch to bypass the circuit. David's illustration is intended for a turret board, but if you prefer point to point it's still easy to follow. Be sure to note the orientation of the 3PDT switch, it won't work if it's oriented differently (i.e. twisted 90 degrees). David Smith's diagram offers an easy-to-follow layout Here's another diagram from Stompboxed, it's a little harder to follow but still helpful. Another diagram for reference. You'll probably want to use one of the larger Hammond 1590BB (or Hammond-style) chassis as I don't think trying to shoehorn this into a 1590B would be terribly easy. The 1590BB is available from the usual suspects, Mouser, Digikey, etc. in a variety of powdercoated colors. You can also go to Mammoth Electronics and get some much cooler paintjobs for a few more bucks, or go crazy with some waterslide decals... the sky is the limit. For this project I went with a purple Hammond 1590BB ... you can almost taste the grape looking at it. These are cast aluminum, so you need to treat them a little more gently than something that's extruded (e.g. try to do more drilling on the drill press rather than punching holes). Punching out the holes with a tool can sometimes take away more metal than you anticipated. I used larger Alpha pots in this build as I had them in the work-bin. CTS, Bourns and PEC also make good pots, and if you want to check out surplus, Clarostat and Allen Bradley are also great choices. The ceramic 9 pin tube socket is set against the chassis with a rubber "o" ring which can help quash microphonics. It's overkill for this build, but I had it in the bin. Beltons are cheaper and work great as well. There is a corresponding PCB to be used with CNC tube socket as the solder tabs are quite small to solder accurately. These can be found on Ebay by searching for "9 pin PCB", and Partsconnexion also carries them. The Russian PIO caps are a little on the large side and have metal shells, so they need to be carefully placed so they don't short any leads. They can also be covered with heatshrink. PTFE (teflon) tubing is placed on bare leads to ensure they don't short either. Also space needs to be given to the open-frame Switchcraft 11 1/4" jacks so they don't bump into any parts or wires when being inserted. Using different colored wire during the wiring process can help you visually follow the circuit if it doesn't work upon plugging in for the first time. Having a rat's nest of the same colored wire makes things much more difficult. Valvecaster wired up point to point On top of the chassis a tube shield will be installed to protect the tube from an errant foot. You can find these in a number of anodized colors from Angela.com. I thought the gold looked nice contrasting against the purple. Top of the Valvecaster with Tube Shield off... ...and tube shield on Hope you enjoyed the build process of the Matsumin Valvecaster Effects Pedal. You can see it's pretty easy to build a great effects pedal without a PCB and just a few parts. Remember to use good quality parts like Switchcraft 1/4" jacks, Alpha or CTS potentiometers, etc. to ensure your new pedal lasts a good long while.

Got a request to make a layout for this schematic, and it turns out it's the BYOC Reverb 2. You can use 9mm pots and board mount them from the component side if you like. There are a few jumpers, though one of them (the one by the lower IC) can be eliminated if you just stretch out that 22k resistor. Also, the electrolytic caps are folded down on their side so things will fit with board mounted 9mm pots. The Belton BTDR-2H can also be board mounted from the solder side. Don't feel like making the board yourself? You can buy a PCB or a complete kit from BYOC.

There are a lot of great pedals out there manufactured by some of the big manufacturers. Unfortunately most of them are relatively expensive and will easily cost over £100. However there is a big market of guitar pedal clones out there. They essentially make the clone sound like the original by using similar components and circuit designs.
For those of you who didn't want 1590A week to end last month, here's another mini layout for you. It's an early iteration of the Rebote Delay that features a simple JFET stage at the input, followed by the PT2399 delay stage. Simple, yet effective. Note: mind the 3 electrolytic caps on their sides in the middle of the board. Here's the schematic for reference.
In this project, we are going to build the perfect Fuzz with all the knowledge and experience that we have nowadays while keeping the tweaks and old character that make this vintage pedal to sound warm, round, and harmonically pleasant.

The earliest version of the MXR+ used an LM741CN integrated circuit, as Pedal Area states there is only a small difference between this IC and the UA741CP (which I already had in my parts stash) but since these are fairly cheap and I'm going for vintage accuracy as much as possible I decided to buy some LM741CN. It also uses 1N270 germanium diodes (which I had never ever heard of before) so I had to track some of those down, which was easy enough on ebay.
Haven't done a tremolo in a while, so let's remedy that with the original 4-transistor Colorsound Tremolo (the re-issue is the 3-transistor version). Originals used 2SC945 transistors (BCE pinout), but I've laid this out for more common NPN transistors with CBE pinout. You might want to use a C100k pot for the Speed control. Here's the schematic for reference.
