This is a quick demo of the Nighthawk we recorded in the shop. It was Recorded with a Zoom Q3 about 8 feet from the speaker. This amp has a 15″ speaker and two 6L6s – 40W. It is based on the 5F6a tweed bassman. It has standard Volume, Treble, Middle, Bass, Presence controls and a Master Volume. The Master Volume can be switched ON or OFF. It has a Bright switch, a Jump”switch, and Bump switch. The Jump switch doubles the input gain just like jumping channels on a tweed amp and is controlled with a dual volume pot. The Bump switch adds a little more gain and changes the frequency response.
