Blu-Tack where to Buy?

Go to Wal-mart. I bought some there in the office/school supplies section.

Office Depot and other large stores with writing supplies have a type of mastic that is very similar to BluTack, but much less expensive. I have used it and it makes an excellent substitute for about 1/3 the cost.

I picked a substitute up as well that was light blue in color and under $2.50 a pack at our local mom and pop hardware store. It doesn't stain (even old unprotected wood)and was enough to make at least 20-24 pea sized balls. If I find the package I will post the brand name.

Dekay and Sdcampbell, What are the sonic qualities of the substitute versus the original "BluTack"? Dekay, do you think the lighter color of blue affects the sonic signature? Cheers, Doug
