Looks indeed like an Electra with an input gain control, a volume and a tone pots.
Patafix... so sticky

is that another greer box?


seems like he and that lovetone guy get lotsa miles out of that little electra circuit.

Topic title edited for clarity. The Electra is worth playing with; I've come up with a few interesting sounding devices based upon it 8)

something I've never liked of the electra is that's too much sensible on the input, use a buffer in front or push it with a booster and it will start to fart out...much better if you add some kind of resistor to ground after the input cap, with 2M2 from the collector a 390k to ground works well to me..if you loose some gain a bypass cap on the emitter res will do a good job too.

Me, too. I came up with a fuzz circuit that is two Electra's in series minus all the clipping diodes:

The Electra is a great little building block.

cj- where are the schemos on your blog?

I forgot to post a couple of schems, including the one I linked. I'll get it posted soon. :oops:

On that tone control in the first diagram, are those caps coming off the lugs just soldered to the side of the pot? Or am I missing something?

one leg of the cap is soldered to the lug on the pot, the other leg to the bottom of the pot.

Ghetto Stomp schematic. It does some nice tweed/silvertone overdrive tones. The circuit board is a postage stamp sized piece of perfboard with no unusual components, basic green film caps and carbon film resistors. It was encased in a ball of black shrink tubing type stuff. I failed to get a pic with the board exposed before I taped it back up.


Oops, didn't see there was a previous Ghetto Stomp thread. Maybe a mod can move this or delete it.

Vero for those interested. I've added a filter cap and LED resistor, which can obviously be omitted if you're not bothered:

So I have an actual Greer Ghetto Stomp. Its great. It has a huge booming low end, which I adore. However, sometimes that huge lowed can become muddy in certain situations. I'd love to but a bass cut switch on this guy. Would it be best to put a switch on the input or output cap? Which one is causing that huge low-end?

Possibly both, but I'd try first with the input. The .1u cap is fairly big for that position... try switching it (with a SPDT) to .01u or if that's too little, perhaps some intermediate value (.022u , .033u)

Regards,
