Any chance of a photo so I can see what's included?

Cool! Are you going to work through the tone stack and PI too? Look forward to seeing more,
Philly

Mine arrived today , too! Cheers!
Phil

Me too!

I ended up making small vero's of each boost circuit - they each sound good going into a Plexi drive but also into a Zendrive. Not so impressive into a TS. :lol: It's funny because they are not particularly fuzzy on their own (and I was expecting them to be fuzzes!) but into the Plexi they give that...

I built up the boost section but I'm getting just splatty farts on the tight side and zero on the fat side - I have triple checked component placing and all is good. Also the soldering is clean, so I'm wondering if I've missed something? I'm using a 2n5088 instead of a 5089 but the pinout is the sam...

Finally got mine up and running - a very interesting circuit! I like the sound of the op-amp only overdriving but I would have liked a little more compression. The LED's were way too harsh for me (but fun!) so I tried various combinations of diodes. The more I play with it the more I like and then h...

Thanks - got to wait for a few parts to arrive before I can complete it and it had me worrying
Did you do any more work on the circuit or were you totally happy with the final version?
Cheers

I see capacitor 11 on the BOM but not on the schematic or vero layout - is this a typo or is the layout missing something?

Final little update - breaking the signal at R31 on the main output gives you the "vibe" setting. Only downside is that it kills the dry signal when you switch the pedal off, so you need to convert the pedal to true bypass to do this. Personally I didn't think the vibe sounds were that use...

O.k. - I know I need to kill the dry signal where it gets mixed with the modulated signal. I'm assuming that's IC2 on the schematic but not totally sure - anyone kindly point it out for me?

I know this is an old thread but I just got hold of a SCH-1. What's the least invasive way of adding a Vibe mode? I'm also going to add a pot in the battery compartment so I can tweak the volume - the boost when you turn it on it was too much at gig volume.
Thanks in advance,
Phil

Forget it - found it! Sounds cool - way vintage

HI Guys Finished soldering up my trembulator today, but have some troubleshooting. The led flashes for a few seconds then stops (off) - when I touch the underside of the pcb it starts up again for a few seconds. I can't see any obvious errors - where should I be looking? I'm using TL072 and a pair o...

Magic - thank you!

HI Guys
I want to build one of these but am having trouble finding the IC's - JRC062D's are not easy to find. Can you suggest a substitute?
Cheers
