    Hi, only to say THANKS for your layout, I have used it for my own TS pedal and it sound gorgeus, again… Thanks.

    Hi, I did an alternative layout with groundstar and no wire links as well as mounting holes, will you e-mail me so I know what address to forward the files to…

    Many thanks

    HI again. I just finished the Tubescreamer from your layout and Schematic. Plugged it in on bypass and heard the guitar…but when I switched the FX on no sound came out. What could be wrong??. I did solder together a tracing probe with a .1uF cap to tip of guitar cord and the shield to the ground tab on the plug socket. I plugged the cord to the amp and the ground to fx ground and put the amp on low volume but cannot hear a thing??. Am I using the tracer the wrong way??. Should I plug the guitar into the fx first??.
    Thanks a million you have a really good website and I hope you have found a home to settle into. Right now I have my daughter, son-inlaw and 3 kids and 3 cats to boot….they sold and are inbetween homes :). It could be worst!! I lost my hobby room to them but I do love them alot.
    God bless.

    hey hey!

    good idea to put together an audio probe. let’s debug it off-line and post the results. i’ll send you an email.

    I’m thinking of building my own clone tube screamer, I’m interested to buy the pcb.
    Do you provide it?
    If not where can I get it?

    First of all thank you for share your designs so unselfishly.

    A while ago I modified your eagle layout of the Tube Screamer in order to put some mods there. And I’d like to publish it on my new diy blog. So I’m asking for your permission to do it.

    Also i’m working in a Dr Boogey and I’ll make some mods too, like two footswitchable channels, modify the tone stack and maybe more. So I’m goiing to modifiy your eagle layout and I’d like to publish it to.

    My e-mail is

    Thank you and thanks again for sharing all your knowledge

    Dear Seba,

    Thank you for asking! You are welcome to publish your modified versions. Actually, that is exactly what I am hoping people will do with the material on this site so I am pleased to hear about your work.

    When you post your stuff, please post links on the appropriate pages. And if you are using WordPress, a trackback would be nice, too.

    Cheers, Paul/GM

    Hi Markov,
    It’s not clear for me the difference between a pot type A or B.
    In Italy A is a log potentiometer, and B is linear. But in USA is the opposite.

    Can you help me in tubescreamer scheme and specify the potetiometer?

    Hi there,
    I’ve built the tube screamer based on your schematic, but something is not right. The output volume is way lower than the input one(should not be this way since there is an Op Amp). I used on some resistors close values to those specified by you, but something is not right. If you can help me, at least with some ideas, please send me an email.

    Hey there!

    First of all, congratulations on this wonderful blog. If I had the time I would try out all of the projects posted here, since you’re that kind to design layouts and give out Eagle project files.

    I gave this project a shot but I’m stuck. I used your layout and your component list, but made some changes:
    1) Replaced D3 with a jumper.
    2) Replaced the 2N3904 transistors with 2SC1815 transistors.

    Also I had to make a few more changes due to component unavailability, which I think don’t affect anything:
    1) Used an RC4558P IC instead of the JRC4558D.
    2) Used 1N4148 diodes instead of 1N914.
    3) Used an 1N4007 diode instead of the 1N4004.

    According to what I know, these changes would only affect the sound slightly and not the functionality of the pedal.

    I finished soldering everything, and when I tried the thing on bypass it sounded clean, when I turned it on no sound came out at all.

    I don’t think the problem lies in the changes I made, but somewhere in the process of making the pedal. I don’t know what I could have done wrong though!

    I would really appreciate it if you helped me debug my pedal. You have my email.

    It’s funny how the human mind works best at night, after 2AM. 😛

    The 2SC1815 and the 2N3904 transistors have different pinout. I will try fixing that tomorrow.

    This is a fatal error, but I hope it’s the only one!

    Used this schematic to rig up this circuit with a 3pdt switch and an LED indication light. I did not use asymmetrical clipping on my first build but I have three other boards already made so I will be venturing to try it out. Sounds fantastic right from the get go! Great to have the amazing sound of the ts-808 in a DIY box!

    Hello. I’ve made this project today, works great, but i’ve got a little humming issue. It happens when i touch the guitar strings, and goes away as soon as i release the strings. I’ve got active Pup’s on my guitar and dont have any grounding problem with it, what should i do?

    hello gaussmarkov, i’m writing an article for an italian webzine on some popular TS mod. Can I use your schematics (giving you all the credits) and alter it to show what components affect the ts sound?

    Tnaks for publishing this. I’ve been busy on this build, and love it! I followed your guide, and experimented a bit. I enhanced the artwork to get thicker traces, and latest experiment was 2n3904’s with 1n34 germanium diodes.

    Thanks for your layout in Eagle, Eagles a great program for little circuits. I only have 2 questions: Why 3 diodes? Why a 500K pot for gain? Looking at the gain on the scope, there is very little change. Other than that good job.
