Quoteman, you can do anything, any @#$%ing thing in the entire universe.

man, not me man, I can't get a fecking sound outta this circuit worth keeping it on the breader, yet. man. one more day, I'll trudge back to stock-ish values. then - the scrapyard.

matthew - the input resistor is so way low, it might be worth increasing it some for the recalcitrent pickups. maybe try 4k7 instead of 1k, see if that does anything. each time I switch pickups from H to S, or back, there is a sagging wind-up tone -- or down. if you've heard that sound, you know what I mean.




Basil Fawlty drove a Morris 1500. my sister's first car was a Morris 1100**. so in reference to Christine, I'm allowed to quote Basil when he says:

QuoteOur cars have steering wheels.

** it was like the tardis inside, huge.

Wrong amp.  The correct one is JD Sleep's layout for the Craig Anderton practice amp that appeared in his DIY Projects book (and probably a Guitar Player column as well, IIRC).  The basic amplifier assumes there will be some sort of preamp/buffer/driver stage ahead of the input, where signal level being fed to the power amp could be adjusted.  After all, this is precisely what larger guitar amps do - volume is adjusted BEFORE the signal gets to the power stage.

On the other hand, as the schematic shows, the amp is essentially structured like a big powerful op-amp.  The range of possible usable values for feedback resistance and ground leg are shown.  If the goal is to simply reduce the maximum output level, without any need for intermittent adjustment, then the implied course of action is to reduce feedback resistance R2, and increase ground leg resistance R3.  So, for example, R2=4k7 and R3=22R would give highest gain and volume, while R2=2k2 and R3=270R would give much less gain and volume.

Make sense?

Great! Thank you for the update. I'm excited to see the outcomes as well.

Whoops!

I got confused by the sw1b being left at the bottom of the page unattached. 

Thanks Great pedal!

If the recovery stage has a capacitor for the low pass filter, it would be very useful for me if I could switch the value between the original and the low pass filter.

Alright but at WHAT frequency..??

I think it would be about 3k Hz, taking into account that it is 6db/oct.
I believe that combining this with Electra Tone controle will give an attenuation close to 12db/oct.

I wonder now if it is possible to use a 3.5mm output instead of piezo so that I can use some in-ear's to hear the BPM on the live stage. If not, would a basic booster circuit help to increase the sound to a headphone level?

Switching from a piezo to a 3.5mm output for in-ear monitoring is feasible. There are various amplifier circuits available that could help with this

Thank you much brother sir. I do like the make a song with the glitch when the LFO is running it in circles.

Update on my guitars, Ibanez is H-S-H (edit: used in video), Samick is H-S-S both bridge to neck like that.

Also, "Let me tell you a little something about love,... It has a voracious appetite. It eats everything. Friendship. Family. It kills me how much it eats. But I'll tell you something else. You feed it right, and it can be a beautiful thing, and that's what we have. You know, when someone believes in you, man, you can do anything, any @#$%ing thing in the entire universe. And when you believe right back in that someone, then watch out world, because nobody can stop you then, nobody! Ever!" you got that right Arnie, man, she believes in me!

Kool build Matthew, great video, watched it to the end. Rated PG. Suspense, sifi, no smoking.
