A downhole tool includes a thru-tubing high expansion, elastomeric inflatable seal and a thru-tubing mechanical anchoring arrangement. The quantizer, loop filter, and digital to analog feedback circuit have a loop gain associated therewith. The resonance device therefore enables the drum to be precisely tuned to a fundamental pitch in a given harmonic musical concept. At least one of the head sealing surface and opposed cone sealing surface is not cylindrical.
