    Rockman X100 Rev. 10 Schematic Release

    I just read that the delay time is determined by the clock frequency used to drive the MN3007. I am trying to figure this out so I can try to use something other than the 4013/555. Like maybe just a 4046.

    Rockman X100 Rev. 10 Schematic Release

    X100. From what I have read the delay is 20-24ms, and the modulation is between 17-23ms. I looked at the data sheet for MN3007 and the delay time is adjustable between 5.12-51.2ms and represented by tD. But I do not see on the data sheet how to adjust this time?

    Rockman X100 Rev. 10 Schematic Release

    What sets the delay time in this circuit? I want to create a separate chorus pedal based on the LFO circuit for the modulation. But, as I am trying to learn chorus circuits I cannot find info on the delay portion. Electro smash does a great job explaining the circuit portions of the CE1, but I...

    Rockman X100 Rev. 10 Schematic Release

    Thanks for the replay! I ordered a PCB for a EHX small clone and still waiting for it to arrive. Anyway I can get your final schematic for the what you did on the chorus? That was my intent to use the Small clone and try to convert it, but the clock is using a 4047 instead of the 555. I do...

    Rockman X100 Rev. 10 Schematic Release

    Cybercow Hello, and congratulations on all your work and thanks!! I am only interested in the Rockman Chorus and Echo portions. I have tried re-creating the Chorus schematic on more than one occasion with no success. I really want to get the circuit working but I am almost done trying. I do...

    Ocelot question

    Thank you for that information! I found a vero board layout (see attached). Anyone know if I use this layout with a 4027 (not modified) if I will get the low pass filter dupicate? Rob, do you have any rev 1 ocelot boards still to sell?

    Ocelot question

    Hello Per the instructions on page 2 it mentions that if we install CD4027 with no modifications to the IC that octave 2 will work as a low pass filtered duplicate of octave 1. Does anyone know what part of the circuit does the low pass filter? Can we swap any devices to a pot to make the low...

    Six band eq low output

    Hello I used the six band pot board to create a Mesa Boogie 5 band eq and it works. But when engaged the volume drops a lot. I took out the two 10k resistors on the input and output stages and installed 250k pots and got more volume, but now distortion. Is there a way to increase the gain to...

    Equalizer Q value

    Is there a window to try and get the Q value into?

    Equalizer Q value

    Hello I am building a 5 band EQ with same controls as a Mesa Mark amp. I am using the board I got from PedalPCB, and changing values using AMZ FX gyrator calculator. My question is, for the Q value, does this need to be a small or large number? Or does it really not matter? Thanks Rob

    DriveGPT PCB - Arriving Soon!

    I made this pedal and love the clipping from it, but it sounds thin. Kind of restricted. Is there a way to let more frequency through?

    using NPN instead of PNP in fuzz

    Can you use 2N3906 in place of the (3) GE's called out in the BOM?

    New project stuff maybe?

    Are you planning on trying to make the Uber board?

    New project stuff maybe?

    I once had a Victory Kraken, and the one thing i liked about it was the switching. So i made a pedal that allows me to switch in another preamp pedal that allows me to have basically a (3) channel with my Marshal DSL40C based off the Victory switching scheme.
