Dating vintage ampeg amps
Amp just thoroughly serviced, grounded cord added.... A rare find as these higher watt 50's Fenders were expensive in the day.
This one has that high power twin tone like Keith's.
YES, this deluxe was used on that album and you can see Thom's name credited on the ablum covers.
Also you can see on Fender Tube Chart dated OD, meaning 1965, clearly Thom's full name and phone number (at that time).
The preamplifier is a voltage amplifier that amplifies the guitar signal to a level that can drive the power stage: the signal is made larger, but without significantly increasing its energy content.
There may be one or more tone stages which affect the character of the guitar signal: before the preamp stage (as in the case of guitar pedals), in between the preamp and power stages (as in the cases of effects loop or many dedicated amplifier tone circuits), in between multiple stacked preamp stages, or in feedback loops from a post-preamp signal to an earlier pre-preamp signal (as in the case of presence modifier circuits).
produced distortion effects by connecting the already distorted output of one amplifier into the input of another.
For those readers who may have joined us recently, I am doing some Fender amp research along with Devin Riebe and Greg Huntington.
The tone stages may also have electronic effects such as There are two configurations of guitar amplifiers: combination ("combo") amplifiers, which include an amplifier and one or more speakers in a wooden cabinet; and the standalone amplifier (often called a "head" or "amp head"), which does not include a speaker, but rather passes the signal to a or "cab".
Guitar amplifiers range in price and quality from small, low-powered practice amplifiers, designed for students, which sell for less than USD, to expensive amplifiers which are custom-made for professional musicians and can cost thousands of dollars.
Our research efforts are now in their fourth year (will it ever end? Part 1 and Part 2 of this series can be found in the March 1997 and November 1997 issues of TCG, respectively.
Again, I would like to thank everyone who responded to our request for data as outlined in Parts 1 and 2.
