    Quick Mojito BA482 question

    You can without a doubt, whether you'd like the slight difference in sound (if any) is a matter of taste, could sound better, could sound worse. If you can get your hands on some, please let me know what you think of both ! I'll keep you posted on when I'll measure mine and put them in the...

    Quick Mojito BA482 question

    Sorry for the essay, I'll make it smaller: - Clipping quality is subjective, I may like what you don't, in the end we are trying to reduce the quality of the signal by adding distortion. - Curve shows a specific threshold at a specific current - the signal current, the small current...

    Quick Mojito BA482 question

    What I can tell you is that a diode allows some of the signal (here in V) to pass though (to ground for example in some design like the DS1) depending on the current (here in mA). Meaning the lower the threshold, the more signal goes to ground, this creates this saturation/compression. There is...

    Quick Mojito BA482 question

    Oh I read it the other way around... I will get back to you when I added it to the graph. you can compare to the curve in the datasheet of the BA482 in the meantime (just the first line of curve 2, 0 to 10mA):

    Quick Mojito BA482 question

    I think you can fairly say that you can sub a 1SS133 for an 1N4148, you can play around with that graph here and see, double click on 1SS33 to isolate it. I will add the BA482 soon,

    SOLVED Need some ears to help me with a client’s concern about some ‘fizzle’

    Sounds like he is a bit too close to his amp no? Honestly, this is sooooo faint, if anything at all. Not sure you'd even be able to reproduce this in a different configuration

    What strings do you guys use?

    I started using these nylon tape wound strings from Galli Strings about a decade ago and cannot switch back. I replace the G string with a plain one though.

    Measured odd and common diodes IV curves

    I finally put it there as well, I will update anytime I make a modification/addition: Link to the latest plot

    Has anyone tried silicon carbide diodes as clippers?

    Which ones? Google says 1$ for SCS302AH

    Has anyone tried silicon carbide diodes as clippers?

    Hi Darwin, I measured a couple SiC in this thread You can filter for "Silicon Carbide" in the filter upper left corner in this plot The BIRBM... and SIR2424 in this plot are also IR LEDs, have a look By the way, if you end up measuring any diodes I dont have, I ll be happy to take the data...

    "Close Enough" Sub For Germanium Diodes

    Yup, way to go, nope this is a different plot by @finebyfine, I added his data to mine as well. The link to the HTML, you need to download the file and then opened it with your web browser on a computer, works fine with Chrome or Edge. Otherwise you have a non interactive one in PDF: EDIT: I...

    "Close Enough" Sub For Germanium Diodes

    It really is up to you, if they're sold at that price it means people buy them. Is it worth it? I guess at some point I thought so since I have a bunch of them (was a bit cheaper back then around 2008). Do I still believe it was? Meh, definitely not, I'd never spend more than 10 cents on a diode...

    CA3260

    I used the LMC6482IN for drop in replacement of the CA3260E in Ibanez mostortion, I also used the quad version of it LMC6484IN (which is half the price of the dual version for some reason) with satisfying results in other builds, I probably wouldn't hear the difference with any other drop in...

    Getting a PCB made from a gerber

    it looks odd to me but how does it compare to your original file? maybe their viewer is not working properly, happened to me before. sometimes they mix up layers as well

    Getting a PCB made from a gerber

    Was reading thru the thread and intrigued by the JLCJLCJLCJLC thingy, what is that about? 😅😅 I always chose to put manually their serial number in a crowded place where you can't really see it but that's it.

    Measured odd and common diodes IV curves

    if anyone has got any data to add to the plot, I'd hapilly take em :) I will start next month to measure the leakage for each as well

    Bass response of your opamp gain stage and why is the timmy awesome

    Taking two examples, some tend to describe the tube screamer as too "tight", and the very opposite for the mostortion which is often decribed as too "messy", the bass control of the Timmy allows to adjust the low end being clipped, adjusting that "tightness", add this to any opamp gain stage...

    Turn your input buffer (OPAMP) into a (frequency adjustable) boost for 3$

    Watch out, the board is only to add to an existing buffer (connecting IC pin 1 and 2 as well as the ground). you'd need to add the whole buffer circuit (4 capacitors, 8 resistors, 1 potentiometer, 1 dpdt switch and 1 8dip IC) into your guitar, including the power supply (+9v for VA and a...

    Turn your input buffer (OPAMP) into a (frequency adjustable) boost for 3$

    I have been adding this additional control for IC input buffers builds; Deviations of the Ibanez ST9 stage called mid boost, you get a nice frequency adjustable boost to get clipped into further stages, quite nice. Here is the AC Sweep right after the stage (measured between C3 and R4): you can...
