This will be the fourth time I try to build one of these. I made a PCB for the original using the layout from GGG. I never finished this. Then I built and finished a second using the layout from UStomp.com. I couldn’t get this to work. I forget what the problems were, it was more than a few years ago. Franciso Pena, of Tonepad.com came up with a new and improved version that used 13600 in place of the 3080s. I built the first version of this. It was the most successful of the bunch. It worked pretty well but had two problems that I couldn’t seem to solve. With mine you could hear a ticking from the sample rate oscillator and the sweep switch refused to work in one direction.
Anyway, I found a sheet of PnP that I had printed sometime ago of Francisco’s second version of the FSH-1. I thought what the heck, might as well give it another try.
With a great idea from Brian Marshall of Subdecay I managed to get my 9V sample and Hold working. This ties Brian’s Sample and Hold to the Colorsound Wah. This works pretty good. The range of the effect could still use some adjustment.
Here’s a sound sample of the 9V Sample & Hold I have been working on. So far things are going pretty well. It’s based on an idea by Brian Marshall and the Color Sound Wah.
9V S&H Test Mp3
I have this for Sample and Hold effects. Though I have yet to build a really good one.
Here are a bunch of sketches of S&H ideas that I have been testing.
This is the Maestro FSH-1.
This uses a 7555 timer for a clock in an attempt to get as short and sharp a clock pulse as possible.
This is Ray Wilsons Sample and Hold from Musicfromouterspace.com
Here’s an idea from the app notes of the 13600. This one worked pretty well.
This idea came from the Diystompbox.com forum
