WARNING: Tube/Valve amplifiers use potentially LETHAL HIGH VOLTAGES.
Building, troubleshooting and testing of these amplifiers should only be
performed by someone who is thoroughly familiar with
the safety precautions around high voltages.
Fender & others used this imperfect hookup often.
It did the work & contributed its own sound, job done.
This one includes a control so the performer can set a sound he likes. 🙂
