Remember when I was telling you about PCB development? (yes, long time ago...) I finally finished one! It took me a lot of time, but now I am satisfied with my layout:
The LPB1 (Line Power Boost 1) is a boost pedal that was commercialized in 1968 by Electro Harmonix. It is the first boost pedal using a silicon transistor. Indeed, previous boosts like the Dallas Rangemaster Treble Booster were using germanium transistors. Another novelty with this pedal was that it was boosting all frequencies and not only trebles, making it the first clean boost available!
I am currently working on conceiving PCB with Eagle software. It will allow me to have some backup PCB of circuits that I make often or for specific projects. Also, PCB are really easier to work with than veroboard, and look much more professional! And what a satisfaction to have something that you made up from scratch!
Will you manage to recognize on which circuits I am working on?
I recently ordered some laser-engraved plates with the Coda Effects logo. I have ordered through HPM laser, a french company, which was affordable, and people there were really helpful and patient ! (not easy to know exactly what you need in some cases !)
Here is the result before cutting everything:
Ink was projected with the laser on a stainless steel plate. The result is really neat and with 3M double-sided tape, I can stick it to any pedal enclosure I made for a really professional looking stompbox !
Today I received a PCB from Dead Astronaut FX, the Chasm Reverb! Dead Astronaut (alias Robert Henry) is an effects builder based in the United Kingdom. He builds a lot of different effects (fuzz, distorsion, tremolo, delays...), with beautiful etched enclosures. I recently had a crush on the reverb he makes, the Chasm Reverb. It is a beautiful, deep sounding reverb that can auto-oscillate to create great sounding "waves" of sounds, ideal for post rock or prog rock. It is based on a Belton Brick, an IC allowing builders to make digital reverbs. Moreover, it has interesting options compared to other reverbs: a mix potentiometer to choose the amount of dry and wet signal, and a bypass system that let the reverb ends when you turn the effect off. It is called "trails". There is also a "damp" setting and volume. You can find demos on youtube (chasm reverb or prismatic reverb) that are really great sounding! Dead Astronaut can make the Reverb for you, or you can order a PCB to make it yourself. As being a DIYer, I ordered the PCB for a reasonable price of 11 pounds. If you want to make one, you canbuy the PCB here. Robert is very helpful and replies quickly to emails, he gave me a lot of useful informations. The PCB is of very good quality, double sided with a nice ground plane. The Chasm reverb layout is quite nice, and not too compressed:
