My fingers are crossed. I have done a post at my facebook and had many repplies saying that sometimes it takes 50 days to arrive... by the way there is a girl who says that works at the post office who will try to help.

I want the pedal too much! sad.gif


It's similar in Brazil, it feels like playing the lottery when you post something.

Here's the latest on my analog multi-fx cabinet, for anyone who cares... I got in my daughterboard PCBs and they work really great! I have a few tweaks to make so it's going to be another few weeks turnaround. When I get time, this is good start to designing the cabinet and power supply.

Looks impressive and very professional.

Would you say the BYOC community is the best place to start with this sort of thing Youcopin?

I have Electronics For Guitarists by Denton Dailey which is very informative.

I will start modifying my Blackheart Lil Giant and fixing my original Marshall Guvnor pedal, baby steps!

Thanks Posterboy! I sent off the new PCB design with a couple fixes/chanes this morning (below).

As for starting out, here's the steps I took and why. The Guvnor is probably an easy fix too, maybe a jack or switch swap, let me know how it's going, I'd love to help. These are some useful links:

AllAboutCircuits Textbook
Sparkfun LEarn

1) PCB kit - BYOC seems great, I got this Tubescreamer clone from General Guitar Gadgets

This is a great first step, you don't have to worry about parts selection (which is simple but not always straightforward) and you can ensure that you can successfully assemble, debug and wire up a working pedal.

2) PCB & Parts - Lots of PCBs out there to choose from, but you are still following a planned circuit. You can attempt to select the correct parts & materials from a supplier on your own. Debugging and assembly practice again. I found it took me 3-4 before my internal wiring started to really tidy up.

3) Repeat 2 a few times

4) Design your own, PCB etching or stripboard layouts - These are designs that can be found on the Internet and you can implement on your own. They aren't complicated but a few of the lessons learned prior will make sure you're finding success without headaches. For debugging, you probably ok to start with just a multimeter, but if you plan to make more than a few of these I'd recommend building a Testing Rig early. It's really useful.

My bad on confusing the tigersharc with the sharc. sad.gif Mea Culpa! smile.gif I think you are spot on, losing the tigersharc eventually just sounds sorta off putting. It's really not that big a deal.

QUOTE (Rammikin @ Jun 14 2016, 08:24 AM) *
The sharc chip in your ultra was in production before you were married and is still in production. Nothing has changed. You and Todd have the sharc confused with the tigersharc.

Anyway, let's all hope Gabe's pedal shows up.



I can't wait to see your multi fx unit smile.gif Is there any plan to make one that is modular so that units could be swapped out or is that just too much of a pain to build? I"ve always had this idea that a rack with modular fx would be spiff smile.gif That way you could mix analogue and digital bits depending on taste, and all of the switching could be done with a floor controller. You could even have one block or two, be an Amplifier. So that the rack was an entire rig. smile.gif Just thinking out loud really. I"m guessing this is all a bit much to actually build or somebody would have done it. Maybe they have done it and I"ve just not seen it. RAMMIKIN have you seen something like that? You seem to be an authority on this stuff based on your responses in this thread.

Yes, that is exactly what it is Todd. The red board on the left is just an off-the-shelf Arduino with a Midi Shield, total cost about $20+shipping. One of these is required for controlling up to 120 "pedal" devices, which could really be anything. I chose to have this single master unit, so each pedal's daughterboard wouldn't have to handle the MIDI (increasing the cost and complexity significantly).

The purple board is the daughterboard and has two communication wires (and one ground wire), which can be daisy-chained to the master. I'm going to be using telephone jack connectors/wire for those because it's ubiquitous and cheap. Each board has a manual toggle switch, indicator LED, and stored MIDI CC# and descriptive name, which can be changed over USB when connecting a PC to the master.

The beige board with all the pots and mono jacks is the pedal effect board, or whatever you want, to be toggled. Toggling can be done with the PC via USB, the manual pushbutton switch on each unit, or via MIDI with a foot controller or anything else.

As of now, everything I've described is done! I'm getting the prototype daughterboard v2 made now before I get 50+ made cheaply by a Chinese PCB manufacturer. I have to build a rack and power supply, and I'm planning the individual units to fit in this rack. I'm also going to get a bunch of cheaply made blank faceplates from here.

I'd be happy to make some demo videos for ya when you get it all put together smile.gif I"ll ship the unit back of course once I'm done shooting. I'm sure you have plans for these smile.gif

You haven't seen MIDI because it isn't a part of the original spec.


Well, yes and no. CV is the intended control mechanism for 500 series modules, so, no, it wouldn't make sense to have a digital protocol like midi included in the spec. But there are midi to cv converters available, so yes, I have seen midi in a lunchbox. But your Arduino board gives you a lot of flexibility.

Hey everybody!!! I'm totally happy to say that I've received a notification today and it seems to be about the pedal!!! I have to go to the customs tax office the next week and see what's waiting for me...

Fingers crossed!!!! smile.gif

YAY!!!! Sometimes customs hold on to things for a uncomfortable amount of time leaving you not knowing what is happening and where you package is

I have to do some custom online stuff tomorrow and based on it, I hope to be able to pick it up on Thursday or Wednesday. Can't wait to have it in my hands!!

Here's the latest in my pedal cabinet switcher-thingy. I am almost finished with the studio rack to mount everything. Starting to look pretty real.

Hello guys! I'm here just to say that yesterday I used this pedal live with my band for the first time. The results are totally killer! I didn't have enough time to experiment since the soundchecks are usually short but I'm really happy with what I've god with both overdrives.

I'll be back with some sound test, but just wanted to give a first opinion of it, and it's that the pedal is totally killer! It's the cooler overdrive I've ever had in my pedalboard. smile.gif

That is so AWESOME!!! I love thinking about something I made, actually being used on stage somewhere smile.gif Those are such nice compliments to make about the pedal too smile.gif I can't wait to hear your full "review" of it. I definitely want to see a pic of it on your stage pedal board one day.
