Synthbox

Try scaling down to a 470k resistor and a 50k pot. That will get you the same size signal while preserving the original pot's resistance (pretty much).

Tried this.  Had the same effect of muffling and killing dynamics. 

This pedal is rad sounding but as of now it is purely for recording only given the difference in volume... too bad.

Just put an lpb 1 after it

Or a simple FET boost, like a SHO.

ok, i finally have an empty breadboard to try this synthbox out..

ive been meaning to try this for ages..

however most lnks are down now

anyone have the schematic discrete   versions?..

edit: found the schemo...but not with the added filter

the one with the filter...

well i have it working on breadboard, worked first go, ...man this thing is sick..

clip:

i was switching between caps (the 68n)

47n and 100pf..

well worth breadboarding and tinkering with...

i think i may try the octup circuit with it..

the filter liquids had on his sounded really nice, anyone have the addon schematic?.

Is that all guitar?

[deadastronaut]

yep...

edit:

a question..

if i added tim escobedo's octup...would i get normal octave too, or is the octup a 12 fret only type octave?.

[Mbas974]

the sound of this pedal is great !
is it combined to your 4pt delay pedal or reverb or both ?

concerning the synthbox circuit, which schematic did you consider for this test ?

[deadastronaut]

hi, i was just using this schematic in liquids gallery, he has some interesting stuff in there...

still looking for the same filter he was using though....calling liquids

http://www.aronnelson.com/gallery/main.php/v/liquids/Synth/?g2_page=2

the delay was in my mixer for ease, but the 4pt delay will do the same...no problem.

i used 5088's btw,

After a couple of days I finally got this thread read! 

First of all congratulation to all you guys working on this project, from the audio demos available I can say that it sounds very interesting and definitely gonna breadboard it. I have a couple of questions though:

1. Liquids: Why did you use a bipolar power supply? Did you try a version with a unipolar one?
2. I know this thing gives you an synthy octave down of the note you're playing. Is it posible to get the normal octave also? From what i understand the "oscilator" part is what gives you the octave down. Have anyone tried to get the signal before that stage? By doing that would it loose all the mojo?
3. Any difference between the v2 (Opamp) and Ronan's version?

here's a neat easy shocktave mod... you can  connect q4's collector and it's base for a synthy same octave sound... i couldn't get at my oscillator caps to experiment with changing the values  so i did some circuitbending     p.s. you can alternately do the same thing to q5 either q4 or q5 and see which sound you like better...   

q4 and q5 that i mention here are the 2 flip flop trannies ,..

[ChanchoPancho]

So you say that shorting the collector and the base of either one of the oscillator transistor's (Q4 or Q5) gives you the normal octave? When I build it, I'm gonna try this.

Anybody gOt a link to a 'good' schematic?

Funny how that works. ..
