"Randy, I received everything (and it works flawlessly)...
I truely think the Compu-Bias is a wonderful product. I did 4 amps with the new unit with no issues of anykind.. Way cool and very quick. I think even better than the product is your support. I will always go out of my way to "good mouth" both the Compu-Bias and Mission Electronics to anyone that will listen to me..
Thanks so much"

I'd like to thank and congratulate you for the outstanding level of support here! My Bassman really sings now......."
