The Kitty Hawk Testarossa is a 1989 German all-tube preamp rather than a head, with five ECC83s, relay switching, a line output and an op-amp filtered Studio Out. Clean and Crunch share a treble, bass and middle stack, with Clean Volume, Crunch Volume, a Crunch Hi-Filter and Crunch Master. The Lead channel has its own stack and cascaded stages with Lead 1 and Lead 2 gain, two Lead Masters and a Bright control.
