Seek Wah

Well, this was a nightmare build. And it didn't turn out great in the end. I had no problems in getting it to work following the info i found here. The problem is that no matter how much i tried, i couldn't get it to not produce an annoying clicking sound. After having build the first PCB, i decided to just build the digital part of the circuit, the part that sequences the leds. I built it on the breadboard and connected it's ground to a small amp i use for testing, and there was the same clicking. After a process of elimination i found two types of clicking. One was on the lfo circuit that generates clock pulses for the counter ic. And the other clicks were due to the leds coming on and off, if all were fully lit, there was no clicking.
After some browsing into different types of lfos, that were supposed to solve this issue by having a trapezoid shaped wave instead of a square wave, and even using a 555 timer chip instead of the lfo, nothing was solving it. The 555 timer worsened the situation a lot. Finally, a simple resistor eliminated the lfo clicking, but i couldn't do anything to solve the led clicking, but it's much more subtle as it was when i started. Not happy at all with this build. I hope it's owner isn't as picky as me.

Octave Fuzz and Tremolo

My build of a Tycobrahe Octavia and a Heartthrob Tremolo.

I'm not into Fuzzes so, i'm yet to figure out if it sounds good or not... But i do think i'll spend some more time on it.
The tremolo has a few problems. I'm going to try and make another pcb with buffers and pull down resistors, because it loses volume depending on where it is on the chain or what pedals are on with it, and it pops loudly sometimes when it's turned on or off. Other than that it sounds great, simple and effective.

5150 Pedal

I was asked by a friend if i could make a distortion pedal that would sound like a Peavey 5150. So i thought, if someone had done it for the Mesa Boogie Dual Rectifier with the Dr. Boogey, maybe i could do the same for this one. I found some schematics on the web, and got to work. This was the breadboard i tested it on. Surprisingly (considering my lack of experience with the breadboard) it worked right away. And sounded pretty good. So once the customer gave the OK, i got to ordering all that was needed to make it.


I decided to make one for myself as well. The one with 8 knobs is mine. The other one was made for Marco of the band Omission . His was simpler as he only wanted to switch between two volume settings and of course, turn the effect on and off. Mine had independent gain as well.





This is a quite different type of distortion from what i had so far, much brighter. But i like it. Always nice to have more options.
