Very nice features, looks great to me! what about calculating dotted 8Th's' etc ?

Yep, the PTAP does quarter/eighth/dotted eighth/triplet eighth. It may even be possible to set the 2 chips to different divisions for cool polyrhythmic sounds, but it's not a definite yet.

That does it then, I've now thrown my name in the hat twice now

I'll take a PCB when they're done - and thanks for putting this together Taylor.

PCB, Rick?

The other Perfborgs are going to excommunicate you...

There can be only one!

tap tempo for the delay using the PTAP
double time mod using a second PT2399
effects loop
modulation kill switch
feedback filter, to get filtered analogish repeats
oscillate momentary stomp switch
board mounted pots
mix pot

Too tasty to turn down I'm afraid!

I would definitely be interested in getting one of these PCBs.

sinner · « **Reply #26 on:** January 20, 2010, 05:56:12 PM »

I would like to get one as well, 5 for future projects if the price will be low

blunder · « **Reply #27 on:** January 20, 2010, 06:19:32 PM »

I'd be down for a couple boards as well. This looks like a fun project.

I don't care what features get chosen, but put me down for two.

aziltz · « **Reply #29 on:** January 21, 2010, 12:25:37 AM »

definitely interested in this project taylor!

perhaps you could add a preamp to the output akin to the echoplex-style FET boosters?

Taylor · « **Reply #30 on:** January 21, 2010, 12:55:24 AM »

I'm not familiar with that, except that I remember some pedal company selling an Echoplex-derived standalone preamp.

What does this preamp do that's special?

aziltz · « **Reply #31 on:** January 21, 2010, 09:10:40 AM »

its just a tonal thing. i've been thinking of including it in delay/loop pedals on the wet signal only for a more "tapey" effect.

here's some info. http://www.madbeanpedals.com/docs/FatPants/Fatpants_ver1.pdf

but of course, i just realized this could be inserted by me if theres a wet signal effects loop.

Adding boost before the PT2399 isn't a great idea, the chips runs off 5 volts so there's not much headroom to start with, if you start adding boost, you're not going to get anything "tapey" you'll just get horrid opamp clipping. It's possibly something to experiment with if Taylor adds an effects loop, but I don't think it's worth building it in.

I think aziltz was thinking about putting it on the output

To filter the sound maybe?

yes, output.

Taylor · « **Reply #35 on:** January 21, 2010, 05:06:46 PM »

Yeah, I don't think I'll have room to implement that.

aziltz · « **Reply #36 on:** January 21, 2010, 05:52:18 PM »

no worries, i'm still wanting one. will there be an effects loop send/return?

Valoosj · « **Reply #37 on:** January 21, 2010, 05:54:41 PM »

Have you ever built the Echo Base with double delay time? I did and I had a lot of problems with the feedback being too silent (after the second repeat you couldn't hear any delayed signal anymore). This problem has been addressed in the Echo Base topic, but Slacker hasn't gotten back to me on it.

Taylor · « **Reply #38 on:** January 21, 2010, 07:57:08 PM »

Actually, no I haven't, but I have read your posts about it. I know it's doable because I think there's a BYOC project that does it. It's something that I have to experiment with to get it working right.

Skruffyhound · « **Reply #39 on:** January 21, 2010, 09:05:52 PM »

Dammit, I'm sitting building an Echo Base, but this is starting to sound too attractive with all these mods nicely integrated. I'm in.
