Flange

Original New York Electro-Harmonix Deluxe Electric Mistress. It's a flanger with a filter matrix (basically the filter matrix is the same as the flanger but without the sweepng effect). Has dry and wet outputs which is a bonus for an effect like this and it pretty much makes you sound like you come from the 70s and maybe were in Hawkwind.
Amazed that it is still going strong after all these years.
Photo taken in a dark room lit only with a torch that has been moved during the shot (lightpainting).
Ilford FP4+, developed 8:30 in undiluted Xtol.
I'm going to take pictures of all my musical instrument kit over the next few weeks as I need to get some experience with developing and I'm constantly running out of things to shoot.
