Hello,
while building one of my "Classics", I got the idea of creating a true "rocker", an extremely direct amp without anything
you don't really need. Some flexibility would be nice, so three channels was a must for this amp but with only one
tonestack. This results in a very staight design with flipping in one ore more stages in the different channels.
The first channel is built according to the old nmv amps of "the" British amp company and has consequently only one
channel volume and no gain control. The sound is getting a little bit thinner with low volume positions for getting more
of these nice highs when playing clean sounds. You can also force that by pulling the volume knob for even more highs.
In higher volume settings, the sound is getting thicker and gets more growl and crunch.
The second channel is far away from many known 800er tunings. It sounds more like a very hot plexi boosted with a hot
stomp box. In this case I was inspired by the first channel of my classic head, played with the integrated booster with volume at 10.
The used sozo premium caps force this fat, old and "woody" tone much more, the sound gets more of this wonderful
vintage growl.
Again more gain is provided in the third channel by changing the first stage and adding a fourth stage. Here I use TAD
mustard replicas which provide a much more stable sound, especially in at the lower strings when tuned to drop D or drop C.
For more gain, just pull the volume knob...
After more than a half year of planning, designing and drawing the cad-files I got the first set of chassis just at the beginning
of the new year. As always made of 2mm stainless steel.
The eyelet boards are made of 3mm FR4, a related design I first saw at Larry’s amps.
The master section is controlled by master volume, depth and presence. The feedback can be adjusted by the last push-pull switch which
changes the sound from aggressive to smooth.
In this amp, there is no fx-loop. But it is possible to integrate my switchable parallel/serial loop which doesn't affect the
sound at all.
There are almost no bypass caps in the amp or if used, they are of very small values like 50pF. This gives the Nighthawk a deep and wide sound with smooth highs. These highs are sounding much more "natural" and "integrated" in the sound then the standard 470pF/470k combination.
After weeks of soldering and tuning, the nighthawk was ready for his first "free flight". So here some pics of it, when "he" came back.
