very cool pedal, does everything.



Looks a little like that.

Similar to the Dr Boogie with a lower parts count yet capable of a similar sound.

Cool stuff.

Went to change a Q, the trace came off when I was desoldering the middle leg of the transistor, effectively cutting the circuit.

Any ideas how I can get around it?

I'm wondering about getting a bare wire from the trace before the Q to after the Q and then soldering the tranny legs to the wire, but not sure if this would work.

Hey guys,

I need your help with my snack shack. It works, just nowhere near like it should. It's shrill, icepicky, and does nothing more than increase the volume, give a little bit of breakup and give me insane amounts of treble regardless of the setting. It's mildly overdriven but it's such a horrible sound... so crazily bright and in no way shape or form anything like the Meathead it's designed to imitate.

I didn't build this pedal, someone very generously built it for me, but it's like a very very harsh treble boost and zero fuzz... imagine hearing your guitar played through a tiny 1950s radio where everything sounds like it's coming through a tin can. it's like that.

OH, forgot to mention the fact that I'm picking up radio stations with the knob past 3 o'clock.

Here is the pcb:



Everything is stock with the schematic except Q2 (which says SK3020) which I was told is around hfe 400-500 as I was looking for something with ridiculous amounts of gain/fuzz for use in a collaboration with a techno DJ, which is due to be coming up soon!

The wiring is very well done, it's all soldered neatly and perfectly so there's not a problem with cold solder or anything, as you can see here:



So, what's up here? What can I change to make it sound like an actual DAM Meathead? I checked the schematic/diagram on the madbean pdf and it looks good, except that C1 and C5 (the red ones at the right of the PCB) look like they should be going into the holes at the top of the board and not the ones beneath them, which look like they should be left empty according to this:

so any ideas guys? I'm really looking to turn this into a meaty beast, as right now it's unusable.

In case you're wondering, I'm using a Les Paul into a custom designed amp (Soldano lead 50 crossed with a Mesa Mk II) so it isn't the guitar, amp, or leads.

EDIT: just checked the datasheet for the RCA Sk3020 (the tranny in Q2), apparently the hfe is 125... could that be responsible for the lack of gain and tinny/buzzy sound?

Edit 2:

I didn't include any shots of the business side of the PCB before since I didn't have any, but now I do. Upon closer inspection (and better lighting) I can see they're are a few solder bridges and also one or two cold solder joints, but I'm not sure if this is an issue.



this might be a better angle of everything:

OK... I'm sooo close to finishing this pedal and finding out it doesn't work and I'd really like ot add the LED since there's a hole in the enclosure for it.

I read in another thread about attaching a 4k7 resistor to the long lead, then running a wire to the DC jack and running another wire to the empty lug of the switch (this was for a Kronk build).

I have no empty lugs, but I do have the LED, bezel, wire and a 4k7 resistor and the holes on the PCB (long leg in the square?) and would really like to have the added fun of a pink light. So.. what goes where?

I DID do a search but couldn't find anything related to this specific build.

All help gratefully appreciated.

Thanks guys,

Howdy all,

I'm about to pull the trigger on a Snack Shack PCB and the parts list calls for some capacitors. I went to Small Bear to choose the ones from the parts list and they have a lot of options.

namely:

Capacitors, Panasonic Low Voltage Poly Film
Capacitors, Topmay Low Voltage Poly Film
Capacitors, Xicon High Voltage Poly Film
Capacitors, Mallory 150 Series Poly Film
Capacitors, Sprague 715 Series, Orange Drop
Capacitor, Sprague 716 Series, Orange Drop
Capacitors, Ceramic
Capacitors, Silver Mica
Capacitors, Electrolytic

I have no idea which ones to get for the pedal 

Everything else is in the cart good to go but these are proving problematic.

If you have any advice related to swapping something from the parts list for a better sound, I'm all ears

thanks, guys.

These two have fundamentally the same design but the Hyde pedal has the sharp/blunt switch.

Great chunky distortion sound though. This would be a great addition to your offerings
