PEAVEY produced the T-60 between 1978 and 1988. The T-60 was one of the first ever guitars produced using CNC machines to carve the bodies and necks automatically. Peavey developed a whole new production factility to make these guitars. Their advert from 1978 announces the T-60:

THE PEAVEY GUITAR HAS ARRIVED. After a three-year research programme costing over $500,000. Peavey now feel that the time is right for the instrument to be placed before the world's guitar players.  
Peavey is America's most successful amplification company and they are outperforming and outselling every other amplifier on the US market. So what makes them think they can build guitars?
ART. Making a good guitar is an entirely different art to making a good amplifier, it's a far more personal thing. Hartley Peavey personally leads the electronic design team, but despite being a guitarist of long standing he brought in guitarist and engineer Chip Todd to design the guitar that was destined to bear the Peavey name.  
Chip only started the process off. In fact the Peavey guitar has been designed by thousands of musicians all over the world. They've played prototypes in halls, clubs, Men's rooms and on street corners and every comment they made has been carefully noted down and introduced into the melting pot. By this process Chip Todd and the Peavey team have built a "People's Guitar" — an instrument that is for the people, by the people.  
But Chip Todd had a secondary brief — that was where his engineering background came in. From the start Hartley Peavey said that if guitars were to be built bearing his name they all had to be good, not just three out of ten, Variation in quality is a problem that has plagued the famous name guitars, and Hartley didn't want to play in that same ball game.  So Chip Todd had to devise a way of making a high volume of guitars designed by guitar players so that each model offered the same qualities. His answer was computer control. Guitar making is a craft; Chip knew that. but he realised that it was possible to combine the very best elements of hand craftsman- ship with computer control so that a guitar could be built combining artistry of design and the ultimate in technological control.  
Very soon Peavey guitars will be streaming off the production line at over 300 a day. They're produced by an automated method unique in guitar building. An automatic machine cuts four necks from solid hard rock maple at the same time, finishes them, lays on a fingerboard of East Indian Rosewood or maple, lays in the frets and finishes the neck in one operation. At the same time a body cutter and router is cutting the bodies from solid ash - again automatically. Ash from the North of the USA is used for the six string guitar bodies, southern ash is used on bass guitars for its weight-saving properties. The whole thing comes together under computer control — even to the point where the action is set on every guitar by computer calibration. The aim is produce every guitar to the Peavey standard.  
TRADITIONAL: The Peavey guitar is a traditional electric guitar. There's no "space age" designs, no flashy inlays; simply the best materials placed together with the maximum care.  
But one area has offered the technologist real scope for improvement over existing guitars the electrics. The Peavey six string guitar is fitted with two double coil  humbucking type pickups. With the carefully crafted body they'll offer as much bite as any instrument available — whether it was built in the seventies or the fifties. Each pickup has its own volume and tone control and there's the usual three- position pickup selector switch. Apart from a phase reversal switch. there's nothing extra in the control department: at least nothing you can SEE externally. Many guitars have been launched with myriad knobs, buttons and slide controls. These instruments have failed because guitarists want it simple — it's a musical instrument, not a space capsule. So Peavey have produced some very subtle but very important changes to the design of traditional electrics.  
Better  Like most tone controls Peavey's are calibrated 0-10. Usually these alter the tone from treble to bass, and do no more. Peavey's Work much better. As the turn on the control is reduced the humbucking sound that is produced at "full tone" is modified to give increased treble response and then. as the guitarist automatically passes the half-way point on the control —  the pickup gradually becomes a single coil type reminiscent of the "broad-  casting" electrics designed in the early fifties. So at one extreme the guitarist has the full, roaring tone of a humbucker at full cry, at the other the clean sharp sound that belongs to another very different type of guitar. All this is achieved without any extra controls being required by inserting a coil tap in the tone potentiometer. This automatic- ally changes the pickup characteristics as the tone control is altered.  Because of this ingenious piece of technology the phase- selector switch is able to work more fully than ever before. With both pickups selected the phase switch allows the pickups to be played out of phase with each other — as usual, with one pickup selected, however, the player can actually use a pickup with each coil out of phase on one pickup - some amazing effects are possible!  

OPTIONS: In addition to demanding unheard of standards for his guitars — Hartley Peavey also asked for another facility to be granted to potential Peavey guitarists: options. We've all got used to the auto-mobile market offering the same model with various options. now Peavey has done the same thing for guitars. When you go to your local Peavey store to select the Peavey guitar of your dreams you can choose the model that is exactly right for you. Because all Peavey guitars are exactly the same, you don't have to rely on getting the one your friend has. or the one you've tried — they're all of the same superb standard.  Choose  So would you like a rose- wood or maple neck? —- you can choose and order accordingly. with that would you like a head piece with all the machines along the top or do you prefer the three top and three bottom design? (Bass players get four in line standard).  These are real options, the first time guitarists have had a chance to order a “custom" guitar at reasonable prices.
