Vocals on a budget. Old dodge no73. I still occasionally do this. Get a standard Sm58/57 (A new one I.E. not gigged) 60/65 quid. Either beg borrow or steal a Tandy PZM if you can find one or buy a new Maplin boundary mic (Same principle) £25 ish and readily available. Set the boundary/PZM up on a flat surface behind the 57/58 and record the voice with both mics. Mix in the PZM behind the 57/58. Its a crude but effective way of providing the high transients associated with expensive tube mics. I've used this old technique (Dunno who dreamed it up) in the last six months with a very shouty Rock ,n roller despite having the luxury of Neiumann AKG and MXL options and the result is excellent. Saves investment in mics that will otherwise cost £500/1000 and allows you to get good results while you decide what your ultimate mic purchase may be. Oooops, also Maplin do a proper gooseneck breath shield for under £10. Well worth it.
