| Hello, Can anyone help me with information about my '68 Thunderhead. The factory couldn't so they directed me to you. Does anyone have a wiring schematic for this guitar? What function does each position of the 3way toggle switch on the upper bout perform? In an early 70's brochure it list this as a phase switch. And finally, I have observed that on the Thunderheads that Glen Campbell played, the rotary knob pick-up selector switch on the lower bout was replaced with a toggle switch similar to the one on the upper bout. Does anyone have information about this modification? Any information would be appreciated. |

don't let "moodypi" con you out of your guitar! |

I never "con" people out of things. That's just not me (unless I really want them, in which case all bets are off).
Tbur:
I've noticed that about the THead Glen played as well and have always been curious. I've got a 1969 catalog which has the THeads in it, but there is no wiring diagram. I can, if you'd like fax you a copy of the page in the catalog.
By the by, what color is your THead and are you looking to sell it (or donate it... often times, being self employed, I feel like a non profit organization). |

Location: Atlanta,Ga. | Here is the info you requested on the 3 way swith on the upper bout of the Thunderhead:
It is called a phaser/standby switch and is a 3 position toggle.
In the Up position.The polarity between the pickups is reversed by 180 degrees out of phase.The result is a near-cancellation of bass frequincies and an increase in treble.The BALANCE or BLEND control must be in the phaser operating range(+6 to -6)maximum effectiveness is acheaved when the BALANCE or BLEND control is set at "0" center..
Center position: The thunderhead now works like any other guitar exept that the BALANCE or BLEND control selects which pickup is heard..
Down:The Thunderhead is now off or on standby and can be set down without feedback or hum.. |

Location: Nova Scotia, Canada | Hi, don't know for sure but since the extra toggle on Glen's Thunderhead was where the blend switch normally is, it would be logical to think that it was simply a regular three-way pickup selector switch for the pickups instead of "blending" them.
I wonder where thes guitar is now?

Location: Scotland | I'n in London at the moment visiting friends & have just returned from trawling the West End guitar dealers. One dealer has a blonde Thunderhead in very tidy condition with particluarly nicely figured back & sides. This example has a mini-switch where a volume/blend knob should be, but the switch looks recent, so it's probably a later mod. The dealer was asking £1100!!!!! (about $16/1700) These guitars aren't common over here as they were never imported, including this one & my own Tornado I've seen 3 in the UK in 25 years, but £1100!!!!? The silly thing is, because of who & where they are, they'll probably get it.
Another dealer had a tatty mid-70's electro-Artist priced at £1200!!!!!! I just laughed my "what kind of drugs are you on?" laugh & walked out.
