Sparkle Boost perfboard error??

[KerryF]

I just finished putting the Sparkle boost on vero (minus Gain Pot).  It was a pretty fun and easy build (Probably the easiest one I have done).  I still need to get a 5k pot for the gain pot.  Anyone have one?

Thanks,

if you have a 10k pot handy, you can strap a 4k7 resistor across it and get close to 5k....

or...you could use a 3k3 - 4k resistor in series with a 1k pot (most of the cool stuff is at the middle/top of the rotation...)

or...you could use a trim pot in series with a 1k pot...adjust the trimmer to a level where it sounds good clean, and then use the 1k pot to get a bit of "grit" into it....

just some thoughts....

Yea I was just checking this out with the Linear Pot Calculator: http://www.diystompboxes.com/analogalchemy/emh/emh.html

I have a 1k pot.  So how do I connect a 3.3k-4k resistor to it?

How do I connect the 1k pot for 5k?  Sorry, but I want to try to do it now.

Ok, just finished building the Sparkle Boost on veroboard with a J201 and a 100k pot instead of a 5k pot.  I tested it by itself, and with a BluesBreaker so far.  Its pretty sweet!  I have to hook up the bypass to see how much it cleans up the sound.
