Tools, Tones and Toys for Guitarists
I’m not liking the asymmetry of the layout 🙁 However, i believe it won’t look that bad once it’s populated on to the board. Original unit has 2SC1015 transistor, but i made this layout to accomodate more common pinouts. That transistor is so close to the specs of 2N3906 that i don’t think that’ll make … Read more
Big Daddy and Grace circuits have this at the end of their document page: The two circuits are very similar and it may be possible to use a switching system to alternate between the buffer and the gain stage versions. (ROG) Now did i really have a choice? 🙂 Instead of using some monstrous 4PDT switch, … Read more
Continuing Grace Overdrive article at ROG: During the testing of this circuit design (meaning the Grace Overdrive), the thought occurred to try a Jfet gain stage before the 386, instead of the buffer. The impedance would still be high and the 386 would see more signal and clip harder. The result is a pleasing grind and … Read more
Info from circuit designer J. Nagy: The Supa Nova is a very low to pretty high gain, tube-ish, distortion pedal that relies on a MOSFET (BS170) to overdrive two JFETs (J201). The tone controls are designed to provide adjustment to the middle and upper frequencies. Voltage at the drains of Q2 and Q3 should be about 5.4 and 4.7, … Read more
Lethal, rough-edged industrial distortion at its most extreme-the sound of a small amp overdriven way past the limits. Our heaviest, most intense, and just plain loudest distortion pedal.
If i recall correctly, someone requested this a while ago. I think that’s enough for today 🙂 Runoffgroove’s current take on emulating the classic Marshall 100W Super Lead. Read the complete description and history of the circuit from ROG.
When i first looked at the schematic, i thought that there isn’t much point in drawing this – as it is very mildly modded Dist+/OD250 derivative. But then it occurred to me.. There is some psychological thing stopping me from modding a Dist+ or 250. Somehow those seem to be untouchables. So i drew this … Read more
I can’t exactly remember how i ran into this schematic. It is pretty old design and once again i’m having trouble finding more information about it. Anyway. I drew it up and built it. Made some slight changes to the original, such as adding the gain knob and one more 1n cap to tame its … Read more
While the circuit offers nothing completely new, i still think this is pretty nice distortion pedal. Should fit in B-box without any worries. It has a bypass buffer in it, so you’ll need just a 2PDT stomp switch to get LED indication – If you don’t want the LED, then omit the LED resistor from … Read more
Note that in the layout, the 33pf cap was only marked as 33 and so not completely identified. Someone suggested a 33n, someone else thought the 33p was more appropriate, so I suggest socketing that cap and seeing which works best. Info about the original: Introducing the Gain Stage Black™. Stripped clean and pure. The … Read more
