So I am building my bass player an effects box. He is tired of the guitar players having all the fun so he wants to get in on the game. It is going to be three effects in one enclosure. It will be a compressor into a Faultline into a Pork Barrel. I want to use a Road Rage to up the juice for the Faultline. I am comfortable wiring up all three without the Road Rage, I just need a little help with how to incorporate it for the Faultline only. Any help would be appreciated.
All three need power from the DC jack right? So you'd have all three attached to the power lug. Now just insert the Roadrage into the power line to the faultline! Bingo, it's done.
Jacob
Thanks that seems quite easy. So just so I am clear, the wire coming from the Faultline that I would normally send to the power lug of the DC jack is now going to go the the Road Rage pad labeled 18v? Then from which pad of the Road Rage to the power lug? Also there are two ground pads on the Road Rage, do I need to use them both? Thanks.
What I would do is connect the ground wire and the power wire from the faultline to the Roadrage board, the power to the 18V like you mentioned, and the ground to either pad marked GND. Then I would connect the +9V pad at the very lower right to the DC Jack, and the other ground to any of your jacks. I would use the last +9V in to connect to my LED (don't forget the CLR in series). I would do that, because I don't know if the faultline has a CLR on the PCB or not, but I wouldn't use it because at 18V it may not be good for the LED. Also make SURE all your parts on the Faultline are rated for at LEAST 18V, better to be 25V or higher. This includes Caps, IC's, Transistors, and such. There should be no worries about the resistors or diodes you may use.
Jacob
Perfect, Thank you very much Jacob, Marvin
I have this pedal put together now and everything seems to be working fine except the Pork Barrel. It works, however, there is drop in volume when engaged, and I don't seem to be able to get the same nice chorus sounds out of it like the Pork Barrel that I built previously. If I set the controls to just get a nice shimmery chorus sound, the effect is almost not noticeable. Anybody have any thoughts on what the issue might be? Could it be a bad chip?
pork barrel is a complicated circuit, there could be a lot of things wrong...
you'll have to trace it through, but check that the mn3101 is working correctly. Not sure what the best way to do that is without a scope, though.
Hi there ! I'm going to ask you a question about the road rage and i'm not going to open another topic for this, so i'm using this...
Ok let's go... I need 23v or 24v to power a tube pedal... If I power the road rage with 12v, will I get the 23v I need?... I suppose I won't need any regulator for this, won't I?
Thanks ;)
yes, if you use a charge pump that can handle 12V in, and will give you 23V out.
Jacob
Ok Jacob ! Thanks Man ;D... But What about the Voltage Regulator, I don't need it for this simple doubling voltage operation, do I?
???

Nice! I learn something everyday here!
No, you don't need a regulator. The Road rage will work fine without one.
Jacob
Thanks Jacob ;)
I also learn something new here everyday ;)
Sorry for bringing up this old thread.
Where can I get a regulator for the Road Rage? partnumber at Smallbear?
If I'm only going to use it to feed my 9v positive ground fuzzface, what components shoult i leave out?
Should jumper something?
You don't need a regulator to use it for -9v. I don't have the time right now to look and see what you can omit but maybe someone else can chime in.

Yeah, as long as your only feeding it 9v you should only get a yield of -9v, so no regulator would be necessary. You shouldn't have to jumper anything.
I haven't breadboarded this in forever but if I'm looking at the schematic right, the power inversion portion of the road rage only involves pins 1, 3, and 5 of the charge pump. In that case all you would really need would be D3 C3 and C5.
Could someone else please verify this?

Yes, that's correct.
Thanks, I will try to do a stripped down stripboard-version that fit inside my existing FuzzFace then.

I was gonna suggest that. It would be really easy. If you need any help just ask :)
ok, here we go, this is my first attempt to do a layout :P :-[
Will this work, or is this a "fatal destruction unit".
"In" is from normal negative center psu/battery.
I used the part numbering from the RoadRage pdfhttp://www.madbeanpedals.com/projects/RoadRage/docs/RoadRage_ver.3.pdf (http://www.madbeanpedals.com/projects/RoadRage/docs/RoadRage_ver.3.pdf)
(http://home.online.no/~tv79/gitarnorge/+-.gif)
I want to integrate it to my fuzzface. Now I have battery on/off switch where the dc-plug will be.

I didn't study it to close, I'm bad at vero layouts, but you need a 10 uF to connect between pin 2 and 4 on the IC. (+ side to pin 2) You'll also need a jumper between pins 1 and 8. Pin 8 needs 9v or you won't get -9v at pin 5 (Vout)
I think that's it... :)
Josh
You know, I remembered I took a couple of photos of the breadboard when I set that up. I just scrolled through a bunch of pics on my camera and found it. Sure enough I had 3 electrolytic caps and I jumpered pins 1 and 8. Good catch, Josh.
Just don't put the cuts between pin 1 and 8 that will eliminate a jumper. (cuts a5 and a6) I told you I'm bad following vero..lol
Josh
Thanks.
like this?
(http://home.online.no/~tv79/gitarnorge/+-2.gif)
Do i have the polarity correct on all components?
Yes the polarity of and placement is correct. The only thing is you didn't leave holes for the ground connections! You could use a jumper wire to bring it to row E and cut trace between GND and c5 + lead.
I have never done a layout before, and i suck at reading schematics :)
Can you please be more specific? :)
I think you'd just need to put a jumper (a wire/straight line/snipped component lead...perhaps blue or black in your program) from c1 to e1. This would make everything connected to the green wire on the left and the yellow one on the right "GND"
I don't think a trace cut is needed, since the schem has C5+ going to GND...
(ps: you don't need 6 cuts under that IC, just 3.)
Here:

wouldn't that feed negative ground into positive ground?
That might be right, I'm just trying to learn and understand what I'm doing.
I made the same assumption. The schem does have the them connected via ground. Does anyone know about this?
It follows Madbean's working schem and layout, I don't think it matters
see: http://www.diystompboxes.com/smfforum/index.php?topic=51529.0;wap2

QuoteThis is only confusing becase the terms negative ground and positive ground make you think that something is happening to ground. It's not. What changes is the polarity of the power supply. A positive ground power supply is the same as a negative voltage power supply, just called by a different name. A negative ground power supply is the same as a positive voltage power supply, just called by a different name. The words "positive ground" or "negative ground" just tell you which side of the battery is connected to your ground reference point.

There needs to be a ground wire from the power jack to c1.

It's easy to get confused on this, but remember that what is labeled as ground on the output of your board is actually the positive. It's just completing the circuit back to the power source.
Josh
Thanks everybody, this helps a lot.
Hi guys, yet another RR question. My first post.
I'm going to use it to power a ROG Supreaux Deux (http://www.runoffgroove.com/sd.html). It will be the front end to a Tiny Giant amp-based combo I'm building (http://musicpcb.com/pcbs/tiny-giant-amp/). The TG can supply 11V, so rather than adding an extra 18V power supply into the amp, is there a way I can
instead use the extra 11V the Tiny Giant supplies to feed the Road Rage & get 18V out? Could I for instance use this regulator? http://www.mouser.com/ProductDetail/ON-Semiconductor/MC78L18ABPG/?qs=sGAEpiMZZMug9GoBKXZ752YXO9pvfwzmPm%2fAMlkbq%2fc%3d (http://www.mouser.com/ProductDetail/ON-Semiconductor/MC78L18ABPG/?qs=sGAEpiMZZMug9GoBKXZ752YXO9pvfwzmPm%2fAMlkbq%2fc%3d)
Thanks in advance,
Bruce
Welcome!
I don't see why you couldn't. Just make sure you use a TC1044 (the MAX1044 is not rated for that much input voltage) or maybe even a LT1054 (make sure pins 1 and 8 are not connected on the PCB if you want to use the LT1054). Any 78L18 regulator should work. (I would get the smaller TO-92 size like you selected). I have had a little trouble with noise when adding charge pump chips to circuits so I don't know if you will have any noise problems or not. If you build it, please let us know how it came out. I am interested in the Supreaux pedal too.
Hey Shawnee, many thanks for the response & the answers I needed.
I'll definitely let you know how it goes - I'm excited about not only building a "budget Supro", but about the Supreaux Deux pedal itself. John Lyons at Basic Audio knocked out a pair of the PCBs for me at a nice price, so one will go in the amp & the other I'll make as a stompbox.
I hear Zeppelin in your future. ;D
Hi all, I'm struggling towards the finish with this project (free time being what it is).
I've got the RR made. I'm using an LT1054 with pins 1 & 8 clipped off. The regulator is a 78L18.
To test it, I'm feeding it 9V, as the 11V feed isn't ready yet. I am connecting DC to the +9V & G1 connections.
I'm not clear where I should take my output from, but when I measure either at ~18V or +RV, I'm getting 7.9V
1) Where will I take the output from to feed the ROG pedal?
2) Am I getting 7.9V because I'm feeding it only 9V instead of 11V?
Thanks!
Your problem is because you clipped 1 and 8. You only need to clip/modify pin 1.
Jacob
Ah, shoot. I was going by what Shawnee had said, but I should have just taken them out of the socket instead of clipping them off anyway like I did.
Man I'm sorry. That was bad wording on my part. What I was trying to say was that the Road Rage pcb alread has pins 1 & 8 connected for use with the 1044 chip and you don't want them connected together if you use a LT1054. The best way to do that is use a second socket and pull pin 1 off of it. Then put the LT1054 in that socket. So what you have is a stack like this:
1. pcb
2. socket
3. socket with no pin 1
4. LT1054 chip.
Again, I am really sorry for the confusion.
No worries at all, Shawnee - I'm learning a ton, & nothing's gone up in smoke yet.
I did finish the Supreaux Deux today FTM mounted in an enclosure until I finish the amp case. I'm using an 18V power supply for now. It's GREAT, the ROG guys captured a lot of what makes those amps special.
Awesome. I may have to build a Supreaux now. Thanks for not being mad about the chip. If I had known that you were using the 1054 for sure, I would have elaborated on the subject a little more.
Hey all,
I finally finished my little practice amp project, which proudly includes a mighty RoadRage to power the Supreaux Deux front end at 18V. The build thread is here:

Thanks to all for the help - and build yourself a Supreaux, Shawnee! :-)
Broken link is broken.

Sorry, this link should work:

Wowweee!! That's cool man. How's it sound?
Jacob
I haven't got much time in on it yet (I finished it late last night & my wife & neighbors have issues with my tendency to turn anything that sounds good up too loud), but initially ... not a tube amp, but not really like other SS amps either. The Supreaux II pedal is really dynamic, and doesn't sound like anything else IMHO. Also the elliptical speaker gives the sound a character that your normal 8" or 10" speaker wouldn't have.
It is what I had set out to make - an practice amp that reminds me more of the old Silvertone I had years ago than a newer SS or modeling amp.
Needless to say, I'm looking at old suitcases in a different way these days!! :P
