Guitar

December 08, 2008

Over a year ago I was offered a fantastic deal on a Peavey Classic 30 guitar amplifier, for $60. It needed extensive clean-up work at the time, and new tubes, but I bought it. This purchase basically launched me into the world of electric guitars, and a tone chaser was born.

I decided to start upgrading an older Washburn stratocaster style guitar that I'd traded for a low end banjo several years ago. I wanted to try improve the sound of the guitar, at the same time as becoming more comfortable with playing the electric guitar.

Several things bugged me about this guitar, and in general about most electric guitars. It had constant tuning problems, binding, tremolo problems, very thin sounding pickups, inconsistent intonation, crappy controls, and the biggest one of all was that like all classic strats and copies the volume pot is located exactly where I like to put my hand, not to mention the toggle switch which constantly got knocked down to the bridge pickup by my fingers when playing rhythm.
The first thing I did to this guitar was change pickups. I bought a two Seymour Duncan stacked humbuckers, one being the classic strat stack, and the other being the classic tele chrome stack. Both pickups use two coils to cancel hum, while not emphasizing mid-range the way Gibson style humbuckers do. I settled on controls at the time consisting of the 5 way switch with only 3 positions used and one pot for volume. I found the best tonal configuration was the tele stack in the middle and the strat stack in the bridge position, which I plan to go back to at some point by adding a second tele stack in the middle position.

I used fairly heavy gauge strings back then, which this cheaper guitar wasn't designed for. Somewhere along the line the truss rod broke, leaving me in need of a neck. $300 bought me an all-parts strat neck, and all needed hardware.

By this time I began experimenting with a pot placed between the two pickups, which gave me a sort of panning effect, although with a sharp dip in the middle due to mutual resistance. The idea had come to me gradually, since I had been planning to put a third pickup in and was already having difficulty balancing the volume of the hotter strat stack with the thinner tele stack. In search of an appropriate pan-pot, and wanting a third pickup with a starkly different tone, I came up with the idea of using 4 SPDT to allow me to pan between any two pickups. By this time having more than grasped the basics of electric guitar circuit design, I selected my third pickup: a Seymour Duncan '59 replica hum bucker. I found a stereo pan pot at Tony's music, and used push-pull pots for volume and tone, which provided the two SPDT switches, and this is basically the same configuration I'm using today.
After that, several changes took place. The first were simply cosmetic, including new knobs, and filling in holes on the pick-guard. <lj-embed id="3"> <object width="425" height="344"><param name="movie" value="http://www.youtube.com/v/LYCg9h8PhRE&amp;hl=en&amp;fs=1"></param><param name="allowFullScreen" value="true"></param></param><embed src="http://www.youtube.com/v/LYCg9h8PhRE&amp;hl=en&amp;fs=1" type="application/x-shockwave-flash" allowfullscreen="true" width="425" height="344"></embed></object> </lj-embed> Shortly after this video, I grounded the ends of the balance control, a decision I'm still not certain was a good one as it brought the resistance of the guitar down a lot.
A careful setup brought the action down significantly and helped tone quite a bit, and allowed the tremolo system to work again. <lj-embed id="4"> <object width="425" height="344"><param name="movie" value="http://www.youtube.com/v/E_3G5YdHBI4&amp;hl=en&amp;fs=1"></param><param name="allowFullScreen" value="true"></param></param><embed src="http://www.youtube.com/v/E_3G5YdHBI4&amp;hl=en&amp;fs=1" type="application/x-shockwave-flash" allowfullscreen="true" width="425" height="344"></embed></object> </lj-embed> At some point I replaced the saddles with Graph tech graphite saddles, about $70. A monumental change came at a later point when I removed the springs from the back of the body and blocked the tremolo out with an oak block, which made the guitar sound much like a cross between a Gibson and a tele.
This experiment prompted me to search for a new body. I eventually found a hard-tail strat body to meet my needs, made by Warmouth. This was a major cosmetic improvement, and added a warmer dimension to the sound that I'm still getting used to. <lj-embed id="5"> <object width="425" height="344"><param name="movie" value="http://www.youtube.com/v/pVpje6RsgBg&amp;hl=en&amp;fs=1"></param><param name="allowFullScreen" value="true"></param></param><embed src="http://www.youtube.com/v/pVpje6RsgBg&amp;hl=en&amp;fs=1" type="application/x-shockwave-flash" allowfullscreen="true" width="425" height="344"></embed></object> </lj-embed> This rebuild included a complete rewiring using a 500K linear volume pot and a 500K Audio Taper tone pot.
Following this there have been a number of small changes, including better quality nut material, and the words "The Andrew" added to the headstock. Next changes will be Fender locking tuners, and a hipshot drop-D tuner for the low E string, sometime this month.
