Mega Thump Delay - Neptune/Shootthemoon/Taptempo

[MattOcaster]

What up guys,

Finally finished with this monster! Came together surprisingly without any major problems.

Had the Neptune and STM boards assembled for ages but wanted to make full use of the Neptunes ldr - can be activated with the STM lfo or the envelope circuit.  

Just need to sort out the Envelope section and decide what to do with the space for the 2 additional knobs.
Still playing with the Envelope section on breadboard. I had originally intended to make the extra 2 knobs a low and high pass filter for the delay signal.

I also need to add a buffer for the effects loop - its not playing too nicely with some effects.













Kind regards,
Matt.

Damn, dude! That is one serious delay pedal!!!! That must have taken a lot of preparation, planning, experimentation, trial and error, sweat and, last but not least, cursing..... Wow!

Wow Matt! This is beautiful. I love the artwork.

Really digging the looks!

Sweet! I look forward to the update with the completed envelope section.

This is really amazing. Did you consider a control for the envelope circuit as one of the extra knobs? Not sure if it'll work without some modification, but if you used the sense pot arrangement from my Blue Warbler, it would give you a way to have modulation just on the attack (fully CW) or decay of notes (in the middle), as well as an envelope "kill" (when fully CCW). Then the last control could be a tone knob for the repeats (10K pot in series R13 works, but you might need to drop R13 a little). I'd love to know how you planned on impementing a low-pass control for the repeats, that sounds like a neat idea.

If there was ever a thread that begs for a demo...this is it.

That's quite a build.

I like the graphic theme you've developed for your pedals.  I can envision an entire pedal board with it.  It WILL look great.  :-)

SAHWEET!

Looks killer,can't wait to her it.

I agree, the graphic theme is excellent. The color really pops in a galaxy looking sort of way--if that makes sense.

Holy crap, man. That's amazing.

Thanks for all the kind words guys!
If it wasn't for the members here (like Culturejam and JMK), it would not have been possible.

In retrospect I think I posted this a bit prematurely - even though it works for the most part.
I've still got to:

1. Finalise the envelope circuit - a knob assigned to control the sensitivity.
Thanks for the advice Jon! I haven't looked at the Blue Warbler yet. I've been breadboarding a LM386 based circuit as used in the Clari (not). Mr Madbean posted a similar scheme on circuit workshop if anyone's interested.

2. Add a buffer to the effects loop. I thought I could get away without one but definitely not. Some effects simply will not work?! Ie I'll put a tremolo in the loop - works fine, put a different pedal in - no sound at all!

3. Add a tone control - thanks for the suggestion Jon! Or perhaps add an capacitor blend control to adjust the darkness of the repeats. The Neptune is voiced quite dark.

4. Possibly change the Feedback control to a blend control. Always preferred them to just "Delay volume level". But that's definitely a Low priority task.

I'll post any further developments in a separate thread, as it's this pedal is half "WIP", half "Build Report".
Again, thanks to Culturejam for the Neptune and STM boards and JMK for the TapTempo board!
This build would have happened 6 months earlier if a Taptempo board was available - so thanks to JMK for providing.

Matt.

'Tis a beauty mate!

Love the look of all your builds.

That's pretty cool
