  • Another fail!

    Another fail!

    Here is a UBE Screamer with blend knob. I left a resistor out of the mixer and mixed up the Blend and Gain labels, double fail! As long as I’m going to screw things up I like to go all the way! This enclosure looks good! I like the logo outline and the pot labels…

  • UBE Screamer v2

    UBE Screamer v2

    I made an update to the RunOffGroove UBE Screamer from a suggestion in their notes. This version adds a mix control the blends some of the original signal with the distorted signal. The original uses Rx to set a fixed mix amount. The notes suggest a value of 100K to 470K for this resistor with…

  • Weston Audio AD110

    Weston Audio AD110

    I built this as a DIY project. They offer it assembled also. It’s a Eurorack adaptation of the drum sounds from the Boss DR-110. All the sounds are analog, not samples. The project comes as three PCBs and a front panel. It’s all through hole parts. The parts are fairly easy to get. I few…

    PCBs with pots and LED

    I just built a PCB project without the LED taken care of on the board, what a headache! In the old days everything was like that but we have evolved since then! in my most recent projects I have been following the layout used by PedalPCB. I feel like they have hit on an arrangement…

  • 1981 Inventions DRV clone.

    1981 Inventions DRV clone.

    Here’s a PedalPCB Informant. This is mostly the Rat circuit with a few changes. The biggest change is the addition of a charge pump. The charge pump provides a +9 and -9 volts power for the circuit to run off. Effectively this doubles the voltage. I have some reservations about the power supply. The clipping…

  • Serge Resonant EQ

    Serge Resonant EQ

    This is the last piece of musical gear for the year. It’s a fixed filter bank with 10 filters. 8 of the filters are bandpass filters. The highest and lowest bands are high pass and low pass filters. It’s like a 10 band equalizer with synth filters. The filters are tuned to major sevenths and…

    UBE Screamer 1.1.1 build

    Built and tested the new version of the UBE Screamer PCB. Everything is working! Sounds great. This is a good alternative to the standard TS-808 and other overdrives if you’re looking for something a little different. Does great low gain sounds. I built this in a 1590B enclosure from Tayda. I got most of the…

    UBE Screamer 1.1.1

    This is an update of the UBE Screamer board. Same circuit just revised. I had these boards fabricated at PCBWay.com. The quality is very great! The UBE Screamer is a very interesting take on the Ibanez Tube Screamer by RunOffGroove.com. It’s the general circuit topology of the TS-808 but uses CMOS inverters in place of…

    RunOffGroove 22/7

    I updated my 22/7 PCB. I had these boards made at PCBWay.com. These boards are great quality. Very cost effective. I’m a fan of OSH Park.com. They are good when you want only three boards, are in the US and need quick shipping. The PCBWay boards are very clean, they offer a range of colors,…

    DS-125b

    A few months back I rehoused a few pedals into some Boss DS-1 enclosures. This left me with some left over Boss DS-1 PCBs. I rehoused three new effects into DS-1 enclosures. That left me with three leftover DS-1 PCBs. Here is a more detailed look at putting the DS-1 into a 125B enclosure. Here…

    Wata’s Electro Sound Big Muff

    I heard this new song by Boris and it got me interested in the band again. This is apparently an add for a new EarthQuaker Devices pedal. If you haven’t heard Boris you should take a listen. They are on BancCamp here. Reading an interview with the guitar player Wata. It mentions the Hizumitas, her…

  • Build a Muff

    This is a PCB for the Big Muff. I design this in Eagle. I used the Part numbering from The Big Muff Page here. With this board you should be able to build any version of the standard Big Muff. Just choose a schematic and match the part numbers to this board. You can order…
