A few notes regarding the original Muddler pattern:
The hook used by its originator Don Gapen was a Mustad 38941 3X Long streamer, this was one of the long flies. When tying slip wings its important to use waxed thread. The Dyneema I use in most my patterns is too smooth for for wet fly style wings and has to be waxed in order not to slip.
The original recipe is as above but excluding the copper wire rib. The rib is a later addition. The original was tied with metal tinsel that required no protection from the small sharp teeth of trout but later as plastic tinsel became the norm the wire rib was added to protect the tinsel and add additional strength. When spinning large bunches of deer hair I recommend, if you are using regular tying thread a minimum denier of 3/0 waxed is necessary to have sufficient strength to apply enough tension to achieve optimal flare in the deer hair. When tying spun and clipped deer hair patterns your choice of hair is paramount. See my earlier posts regarding tying with deer hair and spinning deer hair.
If I was unfortunate enough to be be given the choice of having only one fly to fish for all species both in fresh and salt water, I would have no problem! The Muddler minnow would without doubt be my number one choice. The pattern I tie here is as close to the original as I can get.
Secure your 3XL streamer hook in the vice making sure that the hook shank is horizontal.
You will need two mottled turkey feathers one from each wing. Cut two small slips one from the same position from each wing feather for the tail.
Attach your tying thread and run it the full length of the hook shank so that it hangs vertically between the hook point and barb. Place the two small wing slips ‘back to back and tie in on top of the hook shank for the tail as shown. This is done by holding the two slips in the left hand while you make one loose turn of tying thread around the slips and between your finger and thumb. Tighten by pulling your tying thread ‘upwards’ This will stop your wing slips from slipping around the hook and keep them central and straight.
Trim off the surplus slip butts diagonally and tie in a length of fine copper wire at the base of the tail. Now cover the hook shank with an even coat of tying thread. This is important to get a tinsel body of the same thickness.
Tie in your flat tinsel about 1 cm behind the hook eye. Wind the tinsel in even close fitting turns all the way back to the tail and the back to the tying in position behind the hook eye. Tie off.
Cut a medium bunch of hair from a grey squirrel tail and remove the under fur and shorter hairs. Stack the hair in a hair stacker. Now measure the hair wing along the hook shank so that it is the same length as the slip tail. Trim the hair wing to length. Now before you tie the hair in place a small drop of varnish on the cut end of the hair bunch, this will glue it in place and also make it more durable. Tie in on top of the hook shank.
Cut two larger mottled turkey wing slips for the wing. Again one from each wing feather.
Tie these in the same way as the tail on top of the squirrel tail underwing.
Cut a good generous bunch. This is where many tyers make the mistake of too small a bunch and having to add more bunches later, to make the whole head. The head should be made of only one bunch of deer hair. Clean the hair by removing the under fur and shorter hairs and stack in a hair stacker.
Place the bunch of deer hair with the tips facing back towards the tail, these will be the collar of the head. While holding the bunch in place make two loose turns of tying thread around the bunch, then tighten by by pulling upwards and the hair will flare. Once the hair is flared make several other tight wraps with a ‘zig zag’ movement as you go towards the hook eye. This will push the deer hair from side to side as you wrap and stop you from trapping the hair and tying it down flat!
