This is a library of perfboard and single-sided PCB effect layouts for guitar and bass. I'm not an electrical engineer by any stretch of the imagination, just a DIY'er who likes drawing layouts. It is meant for the hobbyist (so commercial use of any of these layout is not allowed without permission) and as a way to give back to the online DIY community.
Here's the newer version of the Angry Charlie with the 3-band EQ. Pretty much the Crunch Box with a 3-band Baxandall tone stack (similar to this) tacked onto the end. Pots are board mounted and it should squeeze nicely into a 1590B.
Just an idea, you could an a switch to select clipping, like the Andy Timmons version. 3 position switch with center off. Top position is 50w (original led clipping), center position is no clipping, and bottom position is diode (bat41?) clipping
Thanks for one more great layout, I'll probably try to build this in the future
You can actually use just about whatever value you want in place of the 22k resistors. They're forming the voltage divider. As long as they're the same value, they'll create 4.5v. People generally use values in the 10k-100k range.
there is a mistake on the first two components on the board that are the low pass filter, there is a 1k resistance missingin series with the firs 22nf cap on the input
there is a 1k resistor missing after the 22nf cap on the input, and also the 6.8k resistor on the treble pot replace it for a 10k, i also used a NE5532 instead of the lm 833 and OPA2134 instead of tl072
Hola como estan, hice este efecto pero tengo un problema con el tone stack, el pote de medios al subirlo tambien lo hace el volumen y siento que no hay un verdadero control de tonos, me pueden ayudar..
I got build the pedal, fix the problems (voltage divider with low values) amazing sound. I would like to know if is possible get more mids in the pedal (25k B) pot only get mids at maximun, Can I change the pot value?
Hi, Thanks for this. jut finish building it. Does anyone have a volume drop problem? I feel the angriness in the sound but not enough volume coming through. Any idea how to boost the volume?
Do you have a link for the schematic? Thank you very much!

ReplyDelete3 position switch with center off.

i will do that, i´ll apply de mod on the dpdt switch, it doesnt need any mod on the pcb.
DeleteGreat, I think it's as easy as replacing the LEDs with a connections to the switch.
DeleteNoooo... I just finished the version 2 :( . What's the difference between the V2 & V3? How can I mod muy version 2?...
ReplyDeleteThe difference is just the tonestack. I think it's better to build a new version then modding your current
DeleteThank you!
DeleteYeah, the tone stack is completely different and adds an extra op amp. You'd be hard pressed to modify the V2 board into the V3.
DeleteBuilt it yesterday, works great. Also added clipping options with switch and it became a tight fit, so "squeeze nicely" is correct =)
ReplyDeleteThanks buddy!
BUilt it today. Maravilloso! Gracias!Thank you!
ReplyDeleteto add the presence preset, wich resistor should i replace? 6k8 next to 5817 diode?
ReplyDeleteanyone is having issues with the volumen pot? only works the final 10% of the way
ReplyDeleteAre you using the right type of pot (A=logarhythmic)?
DeleteIs there not a missing 1K resistor at the input, after the 22nF, that creates a low pass filter with the 1nF ?
ReplyDeleteim having problems with the bass control maybe its because of that resistor missing

ReplyDeleteEs normal que el circuito meta mucho ruido?
ReplyDeleteHi friends, can you help me with a problem please.
ReplyDeleteI don't have R 22k, I just have R 24k, can I use that value?
Regards!!!
You can actually use just about whatever value you want in place of the 22k resistors. They're forming the voltage divider. As long as they're the same value, they'll create 4.5v. People generally use values in the 10k-100k range.
DeleteThank you so much!!!
Deletemore mids? less treble?
ReplyDeleteThis is verified I build one and its great, its just like roaring Tiger came out of the cage..
ReplyDeleteGood job!!!
ReplyDeleteBoa tarde. Os Leds são difusos ou auto brilho?
ReplyDeleteBom dia. Funcionou, mas ta com um apito alto.
ReplyDeleteanyone had issues with the bass control, doesnnt seem to work as it should
ReplyDeletethere is a mistake on the first two components on the board that are the low pass filter, there is a 1k resistance missingin series with the firs 22nf cap on the input
Deletebass isnt working for me neither. also seems that i dont get enough distortion
DeleteHow can i put the 1k resistor missing?
ReplyDeleteI built one on 2020/03 and works perfectly!! TY
ReplyDeleteyou have just followed it as it is?
Deletethere is a 1k resistor missing after the 22nf cap on the input, and also the 6.8k resistor on the treble pot replace it for a 10k, i also used a NE5532 instead of the lm 833 and OPA2134 instead of tl072
DeleteI made it as it was, I had no problems with the tone stack, also put a presence knob at the end as in the first version.
DeleteWhere is the out actually connected in the pcb?
ReplyDeleteCan this circuit be run at 18v? The JHS manual says it can fwiw
ReplyDeleteIt can be as long as your caps are rated high enough. Generally only an issue with electrolytic caps. I usually use 35v or 50v
DeleteAwesome, Thanks for the reply!
DeleteWhere can I find the complete list of components?
ReplyDeleteDo you have the original vector file for better print quality?
ReplyDeleteThere is a "transfer image library" page on this website - you'll find the proper files to print an etch there.
DeleteWhy is the IC 072 very hot?
ReplyDelete我用B20K代替B25K会发生什么？
ReplyDeleteB20k应该没问题
DeleteHi friend, i build one of this, and im getting a high frequency buzz when i put te gain or volume at max! Can u help me?
ReplyDeleteI also encountered the same problem. Have you solved it

ReplyDeleteMy pedal is having problem in a voltage divider, a changed the values, but in some moment, the voltage from 4,5 V decreases to 1,0V or less
ReplyDeleteHelp ! I am having problem with the tone stack (very high bass tone doesn't work )
ReplyDeleteHi,
ReplyDeleteThanks for this. jut finish building it.
Does anyone have a volume drop problem?
I feel the angriness in the sound but not enough volume coming through. Any idea how to boost the volume?
