    Jfet biasing issue- Lemon Rockerverb preamp

    Its suppose to be 100k. I guess I could have gotten it mixed up with the 1Meg trimpot for the gain. I will take it out and test it to see.

    Jfet biasing issue- Lemon Rockerverb preamp

    I am almost finished with this build. I am currently working on biasing the jfets. I am able to get all of them set to right at 4.5v except the first one. Using the trimpot, I am only able to get around 8.3v- 9.8v throughout the whole turn. Would this indicate an issue with the Jfet itself or...

    Charge Pump Board wiring

    Mostly the 18v pad at the bottom. Would I run a wire from the DC jack to that and the + on the top right?

    Charge Pump Board wiring

    I am probably over thinking this, but I want to confirm that I am connecting the Charge Pump board correctly. First, I see 2 ins and outs and neither appear to be for ground. It also has 2 +/- holes on the top. I am not planning on using a switch to change voltage, just wiring it for 18v. Any...

    2n5457 replacement?

    I would like to avoid buying more parts if I can, but I also would like to use whatever will work best as a substitute. Thanks!

    2n5457 replacement?

    I forgot to order a single 2N5457 for the guitarpcbmania Sea Lion Compressor that I am building. I do have PN4393, N-channel JFETs, and PN2222A - would any of these work instead or am I better off ordering the correct part? Here is a link to the build doc here: Sea Lion Compressor

    Radium Springs, dual footswitch

    Has anyone tried to wire up the radium springs with a second footswitch so that one controls reverb and one controls tremolo? Is this even possible?

    MAX1044CPA alternative

    Hi, I am currently building a Tracksuit/DRV from Effects Layouts. I was wondering if anyone knows what could work as a substitution? Tayda is out of the MAX1044CPA's right now. Thanks!

    Pandora's Box Bass Toggle

    Actually I found the info! Looks like a toggle to add in an additional 100n cap at c1 is the way. Ive never done that before.. Can someone tell me how to wire the toggle with the caps and board?

    Pandora's Box Bass Toggle

    Hello, I am going to build one of these sometime soon. I have seen the mod of adding a bass contour control, but I was wondering if anyone has done the bass switch like the JHS Kilt v2? If so, please let me know!

    Harmonic Percolator- Tagboard.. switch wiring?

    Alright, so tried tracing the short and decided to rewrite the whole thing. Took me a couple hours but it's working consistently now. I jammed on it for a few hours and it's showing no issues!! I can only wonder how much time was wasted on a shorted wire. This was one of the hardest and...

    Harmonic Percolator- Tagboard.. switch wiring?

    Its not possible to short out the transistor is it? I maybe need to check my 220k resistor. I poked around a little when it was plugged in and when I touched it, it buzzed
