Hello
Sorry if I´m asking a silly qwestion, I´ve been a long time away from stompboxes and guitars.
I´m interested in a Rustbucket PCB, I can see that this PCB isn´t at the shop.
Can anybody tell me why?
It´s out of stock?
Thanks

Sorry for such a silly qwestion, but...what´s the wire gauge that you use for the most usual fx projects. Is there one that´s the most suitable?

Talking about simple projects (with no shielded wire or other singularities)

Thanks, best regards.

Hi folks.

I'm debugging a Honneydripper. The circuit is working and I can hear the envelope. The problem is that the fx is not as deep as it should be.

Using the audio probe, I've check certain points.

I've got signal without envelope at pin 7  (JRC4558)

At pin 1 (JRC4558) I have signal with fx, the envelope here is even deeper than in the fx out.

I'm wondering....Is it working right? Is this behaviour correct?

Regards folks!

Hi crew.

I´ve noticed that my honeydripper doesn´t sound as the original dipthonizer. The two pots and the switch seems to work properly. The box makes different sounds in yeh, boh, wah, and yae positions. The sweep and fuzz pots also work.

I can hear the auto-wah (or envelope). But I´ve noticed that the effect is very subtle. In the samples that I´ve heard of the original dipthonizer, the fx is much more noticeable.

I´ve noticed also, that I hear always the fuzz, rolling the fuzz pot CCW I can hear (slightly) more saturation, but the fuzz sounds as well in CW.

Any advice about where I should start looking in would be highly appreciated.

Regards Folks!

Hi there, mates!

I´ve just finished a dig-dug, and It´s almost working, but it seems that there´s a little trouble.

In the non-random mode (sequenced mode), the box gets stopped in the first led. (first led shining and all the rest off). If I touch pin 15 of the 4017 (the reset pin) with my audio-probe, suddenly the box starts to work 100% OK, running in 8, 6 or 4 leds mode. (when I raise the probe it gets stopped again)

Reading the 4017 datasheet, it seems that the pin 15 has to be 0v. to let te chip count the pulses. But looking at the dig-dug schematic I seems that the circuit is not designed for getting 0v in the reset pin.

I´ve measured Pin 15 of my one´s dig-dug and it´s 3,8v.

The qwestion is....is that value correct? or maybe it has to be 0v.

I think that the problem has to be in one of the 4 regulator pins of the 4017, probably pin 15.

Thanks in advance.

Hello

I'm experiencing some problems with my boneyard. The power section is OK. I measure +9v in pin 4 of the LF347, and -8,80v in pin 11. Ground is Ov.

All the remaining pins of the LF347 are 0v, except pins 8 and 9. I've measured -5.80v in pin 8, and -5,67 in pin 9.

I've done double check of the tracks and components. Everything seems to be all right.

The negative values of pins 8 and 9 are caused by the LF347, if I take off the chip, the voltages goes to 0v in both pins.

I've replaced the chip two times (I only have 3 LF347´s available by now), but all of them shows the same behaviour. I'm mystified.

The signal reaches the vol pot. but in pin 9 of the 347 a noise appears, and you can still hear the signal, but noisy.

Any idea of what could be happening?
thanks folks, best regards.

Hello.

I´ve finished my honney dripper with the classic mod:

R5 - 330k
c2 - 560 pF (ceramic disc)
R21- external 10K pot (by now)

But I´m experiencing the next behaviour.

To hear the sweep, I have to put the sweep pot full CW.

With the rotary, in positions 1 and 2 I hear the same fx, I can´t hear the difference.

In position 3, I can hear another kind of sweep. (the second one)

In position 4 I don´t hear sweep at all.

I´ve check many times the connections, tracks, etc...

Any suggestion will be appreciated.

Thanks and regards folks.

Hey folks, I don´t know if this thing could be possible, but I´m going to throw the idea.

The idea would be to put several loopholes into one stompbox, 4 for ex. in order to create a multi-memory-bank looper.  It could be nice to put 3 footswitches, record, playback, and channel switching (memory switching).  It could be nice to add a device to stop recording and start playing a loop in only one push. (maybe pushing the play button when recording?, I don´t know if this thing could be possible)
I will study the ISD1020AP datasheet.
Thanks.
