Q: What mics are suited for harp playing?

A: From "Re: Mics" 8 Mar 93 JE:

SHAKER: I have a friend who has a shaker and he likes it. I think the size and light weight have a lot going for it. I gave it a try using a chromatic and was able to get a clean sound, with little or no distortion - to me a sign of a good mic is how clean you can get it - even if you don't intend to use it that way.

ASTATIC JT30 vs. HOHNER BLUES BLASTER: - Both are made by Astatic. I like the volume control idea on the BB but think it is also available on the Astatic. - I got an old Astatic JT30 off a guy about a year ago. It was mounted on a desk stand and had a talk/listen switch on it, from a Ham radio set up. The cable connector was weird. My son rewired it, minus the stand, put a .25" RCA plug on it and now I have a nice vintage JT30 - this thing must be out of the 50's at least. Anyway - Hint - Look around ham / electronic swap meets for a deal an old JT30 mic. It was a standard for hams for a long time.

SHURE GREEN BULLET: Never tried one but just wanted to throw in that it is being manufactured again, thanks to the resurgence in the popularity of the harmonica. Think I saw it in J & R Music World cat. and also in Music Emporium Cat.

STRNAD: I tried the chromatic model (same mic just longer). I liked the sound and even with a 16 hole chromatic it was easy to hold. I thought it made my tone sound better. I didn't buy one though, it was not possible to quickly switch harmonicas because of the way it mounts and it covers the whole harp so hand effects (vibrato) are limited. I don't know if that's really a drawback or not. It could be used as an auxiliary mic, set up for special effects - say some chuggin' on a low F harp.

I'm no mic expert - these are just my thoughts,

P. S. If anyone hears of SHURE ribbon mics for sale let me know. I would be interested in Models 315 and 330 -- "Re: Mics" 8 Mar 93 JE

Shure Green Bullet or model 520D (magnetic element, originally a dispatcher or ham radio mike). thicker, bassier, less treble vs. crystal mikes. Can feedback with loud amps. Additional EQ can help -- HA

(FMI: "Re: mic tones" 29 Aug FJM (FMI: "Green Bullet selling price?" 11,12 Sep 94 (large thread)

Astatic/CTI -- JT-30 (OEM to Hohner for Blues Blaster, and to other customizers). High trebly tone, some are modified with high Z pots (5 M ohm) and caps (150 pf) to get a fuller mid-range.

Hohner Blues Blaster (JT-30 design, blue paint) -- HA

Crystal Ball Mike from Kevin's Harps (modified JT-30) Rod Piazza Hot Rod Mike (modified JT-30)

(FMI: "Hot Rod -- Crystal Balls Mic (LONG)" 10 Feb 95 EN) (FMI: "Re: Hot Rod... (Thanks to Elliott)" 13 Feb 95 CF) (FMI: "Hot Rod Mic - More Details" 21 Feb 95 EN) (FMI: ROD PIAZZA CUSTOM MICS" 7 Jul 95 DW) (FMI: "Re: JT-30 Cap" 9,10 Apr 95 RB,JT,MC) (FMI: "Shaker mic" 6 Mar 95 RL)

Shure SM 57 vocal mike (some have said that if you don't need it as a mike, you can also use it to pound nails... fifty years from now -- it'll still be around ;-) -- HA

(FMI: Re: SM57's (was amp mics)" 17 Nov 94 HM (long thread)

Shure SM 58 vocal mike

(FMI: "Re: SM58 mic -A good mike-" 23 Aug 94 CS

Shaker G.C, XLR or Dyno Mic (the GC is another crystal element microphone with small size and specifically designed for the harmonica sound). Old-timers who are used to the Bullets or JT-30s complain that it's weird to hold; others especially like the smaller size, sound and lack of feedback. Everybody loves Smokey Joe Arless, the designer/seller. Some negative chatter about the lack of shielding of the plastic case picking up RF interference. Fingers uses the dyno -- HA.

I began collecting data about the microphones used by blue harp players before there was an internet. I began organizing it into JT30.com in the late 1990s. I accumulated more stuff than I remember. This is some of it.
