Has anyone done this or heard/played one that used this technique? I would think that because the rectification happens at a much lower threshold voltage, it might allow for better sustain of the octave, but it seems most octave boxes just use a boost stage to get past the Vf of the diodes... any thoughts?

Visual aides:

(I hope I posted this in the right place)

I would like to build a simple DI. I don't need any EQ, speaker simulation, tone shaping switches...

Does anybody have the schematics of a good sounding, low noise DI (preferably phantom powered)?

Thanks,

Hi everybody,
here's a link to the other forum, with a 640 ms. of pure analog bliss delay designed by Ed Rembold of ToneCzar Effects :
It uses 3 BL3208B BBD (the Shangai Belling MN3208 pin to pin clone), an SA571 compander, some IC's and various suggested values for the Low Pass Filters. Now the point is that a BL3208B has got 100 ms. of maximum delay time :scratch: . How this circuit could reach 640 ms. of max delay time with 3 x BL3208 is a little unknown to me. Do i miss something? Anyone...

I was looking over National's AN-72*, and figures 85 and 86 show a kind of neat ramp-and-hold circuit, one of which looks like it could be made to hold indefinitely...

So I was thinking maybe it's possible to use a momentary switch, press it for a certain amount of time, and generate a DC voltage output proportional to the duration of the button press, which could then control delay time, LFO speed, whatever.

Anyone tried this? Is it possible? Would the sample and hold actually hold long...

I may have posted this before but My searching sucks soo...

I made 2 neutron pcb's but they seemed really small. I did do a 1 to 1 ratio when I printed them so I thought I was okay.

But I now noticed that the holes for many parts are way to close together for regular sized parts like the caps and opamps. Not to mention if I am going to use vactrols..

So my question to anybody who built this, is this supposed to be a very small board? All of RG's boards look very small comared to GG or...

I've been wanting to try my hands at a fuzz pedal, and figured the Multi-Face from Runoffgroove would be a pretty good place to start. I changed the layout a little, just to make it a bit smaller. Here's my version: Multi-Face (excuse the sloppy wiring layout)

I checked and double checked my wiring on my board and components, and everything seems to be ok. I was trying out the May Queen II version, with a 2N5088 in Q1 and a J201 in Q2. I checked the pinouts at and I'm pretty sure I put them in...

Does somebody have complete article ? please

I made TR1 confusing me)...it is a compressor,and attack/decay unit...?

help help

Can someone help me understand why anderton utilized this type of power supply design frequently in his circuits? are there benifits? drawbacks?

below is an example...

anyone seen a reasonable DIY project for a tube dirven direct box, hopefully one that runs on low voltage (like a 12AX7 tube or something like that)?

Has anyone buit one of this?
I've built two, the first with electrictabs' layout sometime ago, and later the one from Gauss Markov.
Sound very cool, but they are tooooo noisy.
So anyone has solved this problem?

Hey
pretty new here, so not sure if this is the place- but here goes..
tried the liquid sunshine OD the other day, and I was really impressed.
then i read about it, and thought i could use the same concept with 2(?) rangemaster circuits, both with selectable input caps to create a a real Ge OD pedal.. 2 cascaded Ge boosters.
using different input caps for each stage is the cool idea i got from the liquid sunshine.. each 'stage' controlling different freq' range.
so i basically want 2...

Hi!

Anyone heard of the Belton Digilog Reverb Chip? I've ordered one from a german Shop and want to make it work in a Pedal.
There is a schem but I'm too stupid to translate it into a layout. And because the Chip is worth about 20$ I'm not really willing to try it on my own without any help (did I mention I'm too stupid?)... :hmmm:

PLEASE HELP! :horsey:

Cheers,

I have some nice sized sturdy enclosures and I want to do something a little different:
A couple pedals, plus a POWER AMP in one enclosure. It would be so nice for quick set-up, and portability. A few dirt boxes, tremolo and delay, a couple different preamps, and a solid state amp (20-50 Watts or so). Hook up power, guitar, and speaker and that's it.

Has anyone ever seen something like this? I don't know if it's the search terms I've used, but I can't find anything like this.

The things I...

Can guys on the forum help me with creating of this super hi-gain preamp*(pedal)?I have the schematic of the 6505+, and i wanted to share it with you.I have drawn the LEAD channel, and i need some help. How to bias FET's on this circuit (what are the values of the trim pots)?Must I change values of the source(cathode) resistors?Are the resonance and presence controls ok, since i bypassed phase inverter?I will draw the PCB right away when you guys give me some answers.I will appreciate any...

Hey there!

Some days ago i found some awesome soundclips for the Sovtek MIG-50 Emulator here:

Does anybody know where I can get the Layout?

Hi,
fresh from my successful Zen clone I'm fired up to build pedals again !

some few years ago I built a Shaka V but didnt use it much as it seemed very harsh in the distortion unless I rolled the tone right off.

I'm sure it was down to me and my component choices as everyone else ( where Ive seen comments ) seemed to rate it very highly.

Has anyone got good experience of the various Shaka's, and if so which ones with what mods/ IC's / diodes etc for me to try again

I still have the...

I had just done PT80 delay and now had come across the tab tempo that is absent is PT80.
Any possible to DIY a tab tempo?
and adapt to PT80?
This is just a wild idea that base on NO theory.
Do let me know if there is any good possibility / solution to attached a tab tempo into PT80.

p/s: The noise performance of PT80 had surprised me. I had expect a little improment over the REBOTE series, but it turn up to be so quite, even without enclosure.

... has anyone tried this Tube Overdrive from s2amps?
link:

It looks pretty cool and not difficult to reproduce.

Hi all,

I built a Blue Magic OD from the info on the net a few years back and I love it - nice pedal.

I read recently somewhere that its a copy of a swedish boutique pedal - but does anyone know what it is ????

any info appreciated

Pedro

I've read into a lot on the runoffgroove site about how they model amps using fets. when thinking of an amp to model, how do you deduce what needs to be converted to what for use in a pedal? I want to understand this process, its intresting and seems pretty unique. Any info or tips would greatly be appreciated.

Thanks

I am building the Tonepad Boss DS-1 pedal and notice there are two jumpers in there.
I am building the TL072 specs.
Do I use both jumpers or just one?
It kind of looks like you need two but I am unsure.

Seems that the fet muff schematic is lost or deleted...

Does anyone have it ?

I understood it was a big muff without the diodes... 4 cascaded fet stages...

Am I wrong ?

Per chance I found this crazy Wah-wah-page:

babelfish doesn´t like to translate it, and the translation of google reads the same crazy as the site itself is:
