I build each amp like a tank so it can stand up to a lifetime of use and still maintain the rich tonal complexity every Blaze amp is famous for. Each Blaze Custom Amplifier really is a custom designed labor of love and is totaly unique and one of a kind, hand built and stringently tested. I build and test each client's amp one at a time, then tweak it until I feel the amp sounds exactly right. Custom means just that and I will modify any model or even make a unique custom model to fit a specific client's needs or desires.
