You won't get much delay out of it. Maybe 150ms, FYI.

They should be On/On for Mod, Path and Ghost.

Can you describe more what you are hearing? What are you not liking about it?

I cannot say whether or not using MLCC for the SDX makes a difference or not since I have only used film caps in that one. But, the Micro version is still very similar and I have built that with MLCC. I guess I need more info on what you are not liking about it.

There is no reverb through the pedal on its own. Any reverb you might hear is probably from the room.

Probably some pics of the top and bottom of the PCB would be the thing to start with. Low output could be due to a wrong resistor value.

AquaboyDX doc is up!

http://www.madbeanpedals.com/projects/Aquaboy/docs/AquaboyDX.pdf

ABDX doc is coming along. I think people will be happy with the basic explanation of how analog delays work that I've written up for it. Hopefully that will give some insight (it is very basic, though).

The PT2399s can vary wildly in terms of noise. I've pretty much come around to the idea that you really have to audition quite a few to find the lowest noise possible.

Like Jon said, increasing the filtering is another solution. For the SU, increase the value of either C11 or C12.

BTW: if your original PT2399 locked it should work again after a while. It doesn't usually result in a destroyed chip. Try grounding out all the pins to discharge any voltage remaining on the chip and put it back in.

Yay!   So since the docs aren't up yet, can you clarify about the ABDX what BBDs we are able to use and if you got rid of the distortion on the repeats for the V3205?

I've added series resistors to each BBD to help minimize distortion when using the v3205. I won't say that it removes it 100% but it does improve it quite a bit. The doc will have a chart in it that explains the plus and minus of each BBD type that can be used - MN3005, MN3205, MN3008, BL3208 and v3205.

I have 150 each of the new Bloviator and Aquaboy boards so they should remain in stock for a while.

Added: Small price reductions on a few baby boards ($1 or so).

To Do: The Hipster and Egghead are slightly revised from their previous versions and the docs will be updated along with adding the BloviatorII and AquaboyDX docs ASAP.

Please be sure to refresh the Projects page when you load it to ensure all images/info is updated.

Yeah, it should say pins 3 and 4 for output. I'll fix that.

Since you ordered the first two, I had them blessed with the power of black metal. Use wisely.

You can use the MN3101 with the v3205. You do need to use the 1n914 diode on the board to approximate the correct Vgg voltage on pin (not needed with the v3102). Your vgg voltage is a little on the low side but it should be close enough to make the bbd operate correctly. So, whether the problem resides in the clock or the bbd you are using, I don,t know. It would not hurt to have an Mn3102 or v3102 on hand to test.

Here's a checklist.

Have you set the jumpers correctly?
Have you audio probed pins 3 and 4 of the BBD and confirmed there is no delayed signal from the BBD no matter where the BIAS pot is set (the two pins on the upper right of the BBD)?
Have you used the correct value trimpots for Clock and Bias?

Yes, you do not need to include any extra filtering or polarity protection. It's all on the RR PCB.
