Title: Macheen
Post by: gitaar0 on December 04, 2011, 06:40:15 PM
Hi,

I build the Macheen.

It works. Sounds almost as the youtube movies most are referring to. My question regards the drive or input pot. As noted by others that pot does not move in the demo's.

In the max setting mine works as the demo video, but in turning down this pot reacts really strange.
It is not only noisy (crackle ok?) but works with what sound as drop outs and drops fast to a setting that does not deliver much usable sounds. I thought for a moment my pot was broken or the BS170. Checekd that and they are ok.
Is this how it should be?

thanks, Marc

Looks like it will crackle when turned. You might try a 5kC pot in the gain position to spread the action more evenly. You shouldn't experience drop-outs however.
