Effects halp requested...Mike and Aen, PLOX!

Markn951 · Post by **Markn951** » Thu Oct 08, 2009 10:23 pm

I'm building a pedal for a client that consists of a ToneBender and a Maestro Fuzztone in a double-pedal. He wants each to have the standard fuzz and volume controls but he also wants a blend knob for both of them and a switch to switch the order of which comes first. He also wants to be able to run this thing on his Onespot, daisy-chained to all his other effects.

So, I'm pretty much gonna have to wire those two with NPN transistors then. Is the circuit changed or do I just get an NPN, match up the EBC, pop it in there, and poof it works (sounds too easy)?
Secondly, how should i wire the blend knob and the switch?
Thirdly, would the bypass switching just be a regular TB 3PDT switch, with the bypassed output going to the proper input pin of the next switch?

you have clients?

i build pedals to order, usually for much cheaper then anywhere else.

nevermind, i really just wanna get help with this.

The mix is easy. Just get a dual pot, like 2 100k or whatever pots stacked on top of eachother. run the output of the effects into the pots like volume pots, but one of them opposite so as one gets louder the other gets quiter. The tie the middle lugs, output that is, together with 100k (or whatever value the pots are) resistors. Linear mixing like this is much cleaner and easier than blend circuits. i wish i had realized this before i put out Hair of the Dog with a slightly wonky blend in it.

But anyway, I dont know about adapting these

fucked up old pedals

to modern transistors and power, because I pretty much only deal in modern circuits and components (Exception: obsolete telephone chip in HAX)

And I might be able to figure out a switch scheme to flip the before/after of the fuzzes, but I havent got a solution in my head right now. Anyway, It's mikes turn to talk.

aen, that blend is fucking genius. makes me wonder why didn't I think of that?

thanks man!

You need a 4PDT switch for the order switcher:

I dunno if those pedals are positive ground. Maybe they'll work fine daisy-chained. Mike makes lots of things like this, he'll know.

The whole build sounds a bit of a nightmare, hope you're charging this guy enough to cover your time.

Post by **Mike** » Fri Oct 09, 2009 8:10 am

Tim, you only need a 4PDT if you want an LED aswell, which is overkill in my experience.

Mark - Give me some schematics please.

I don't mean to be an arse, but isn't this R&D stuff the kind of stuff he's paying you for? Like... do I get a consulting fee for solving these problems for you?

Also - this guy's ideas are all over the shop. Order Switcher and Blend are mutually exclusive ideas. Blend is the blend of two Parallel signals into one another, hence they are not in series, which is what the order flipper would change - the Series connection of two effects.

I think you need to tell him to ditch one or the other of the Blend/Order Flippers. Otherwise you're going to have to have the order flipper and then another toggle which takes things in and out of series mode for your Blend to work. It's going to be hideous.

When you make a PNP/positive ground pedal into a NPN/negative ground pedal, you have to turn around all the electrolytics and any diodes (basically anything that is polarized).

Markn951 · Post by **Markn951** » Sat Oct 10, 2009 12:43 am

1st, Mike thanks. I know this is kinda my JOB but sometimes I need some help

. Do you really want a consulting fee? how about 2 quid

I was thinking the the switcher and the blend wouldn't work together. I think he would rather have the switch because he wants to cascade them.
I'll post some schematics tomorrow, I have guests over right now.

sorry, Schematic Heaven only has PDF schems.

heres the schem for the Fuzz Tone:

http://www.schematicheaven.com/effects/ ... a_fuzz.pdf

Heres the ToneBender MKII:

http://www.schematicheaven.com/effects/ ... II_pnp.pdf

i also found an NPN version of the schem. so don't worry about that.

Basically now my question is how am I gonna wire this "order switcher" thing.

Sure maybe he shouldn't come to shortscale asking that, but you didn't say that, mike said that. You said "You have Clients?" That's kinda a dick move there, maybe he builds pedals and people like them and want to buy more, why is that such a big thing? Just let the guy make his damn pedals if he wants, you don't have to insult him. Why wouldn't he have clients?

Your post was just unnecessary and rude. He just had a question to ask about building pedals, then you insult him for that? Lay off it.

dude, politely fuck your mouth.

being the polizi di post, sure you read some of his other posts? they make him sound like a 15 year old ditch digger. sure, mine aren't works of art, but i don't go around trying to sell shit to people (who i make believe i have the know how already), when really i don't. and then ask for assistance from people who figured the shit out on their own (or had help from longtime online friends).

i haven't seen any of his work, and i'm sure it's just delish. but the previous posts made me genuinely question what kind of clients he would have.

the "big thing," or the 'insulting thing' is that he's already told this guy "sure, i can make you that, no prob," and then had to ask here in sort of a "hry plz nd hlp" fashion, which comes off a bit 'somethin for nuthin.' to me.

that's great that mike and tim both stepped up with opinions on it, but the fact that he had to ask makes me sad for the guy buying the pedal.

and i might've blown this up a bit with this post, but pm me before you go ragging all over the floor with your bleeding heart about some other noob (other than yourself or I). surely it can be resolved like gentlemen before you slap me with your glove.

it almost sounds like i'm in a bad mood.

the isaac eaton · Post by **the isaac eaton** » Sat Oct 10, 2009 7:55 pm

I haven't read all his other post's, has he done really annoying things in the past? I don't know. All I know is, guy has a question, guy gets flamed for no reason. Sorry If I don't know the rest of his story (this is said without sarcasm at all) Yeah and I don't mean to come off like I have to protect everyone new on the forum, it was just supposed to be a, hey why you gotta be hating on this guy? I think you blew it up a bit out of proportion,

Its all good broseiden, take it easy.

(lol broseiden)

Yes Mark is legit, i'm pretty certain he has put together a B.Y.O.C. pedal and modded a Super overdrive.

This could work both as a sarcastic and serious reply.

Dude.
Tim linked you to this:

http://www.beavisaudio.com/techpages/Pe ... er_sml.gif

This contains all the information you need to do that. Drop the right hand row of lugs (they just flip LEDs) and use a 3PDT footswitch or toggle switch. SendA/ReturnA are the input and output to the FXA 3PDT switch etc. Engineering is all about taking the information you have and using your smarts to move to the next stage.

Looking at that Maestro Schematic. you need to flip the power rails, change PNP for equivalent gain and freq response NPN, and also flip the Electrolytics. As with any new build, you should be prototyping this to iron out any bugs on breadboard before picking up a soldering iron.
