David Allen Strat Pickups – Impressions

gordon

strat setDavid Allen makes a lot of different Strat® pickups, maybe almost too many to figure out what to select. The variability of available sound-clips and videos only adds to the complexity. So when we decided to carry the line we asked David himself what pickups were most representative of the range. He recommended three sets: TruVintage 54, Tru ’62, and the Voodoo Blues SSS set. So armed with our trusty G&L Legacy (swamp ash, hardtail, Emerson wiring assembly, maple fretboard) we set about trying out all three sets to see how they compared.

Dave Allen TruVintage 54

As with many of the David Allen pickups, they don’t attempt to completely follow every excruciating construction detail of the original pickup. Instead they focus on creating the sound of a ’54 Strat rather than just replicating the construction. The TruVintage 54’s are wound progressively in the mid-to-upper 5K range and use staggered, beveled Alnico 3 magnets. Having never handled a true 1954 Stratocaster® (tonally these pickups are modeled after an actual set of ’54 pickups) we can only say that they sound the way we “think” they should sound: Exceptionally clean, glassy, with a bouncy low end. Characteristically, the bridge pickup is pretty light, and to some may only serve to pair with the middle pickup. But the Alnico 3 magnets lend enough sweetness to the high end that it’s not shrill or brittle. So you can actually use a distortion pedal with the bridge pickup and get some decent rock sounds. The TruVintage 54’s are textbook Strat, and hit the mark for those putting together the ultimate vintage Strat.

David Allen Tru ’62

Like the 54’s, the Tru ’62 set is graduated set, but wound from the low to mid 6K range from neck to bridge. They also use staggered magnets but in this case Alnico 5. They are rounder and warmer than the 54’s and a little less glassy. But they project a more soulful nature, and have a deeper rounder bass. There is also a little less quack to the positions 2 and 4, but in return you get one great sounding middle pickup. It’s got good low end like the neck pickup, but more twang and bite. It’s my favorite position of this set, followed by the neck + middle. Overall, the Tru 62’s are a slightly huskier sound than the 54’s but certainly won’t be mistaken for anything else than a Strat.

David Allen Voodoo Blues SSS

The Voodoo Blues set is a light top/heavy bottom set with a twist. The neck and middle pickups are wound to about 5.8K with staggered and beveled Alnico 5 magnets. These are right out of the David Allen ’69 Voodoo set, and you  get one guess as to what tone they were aiming for. They are bright and glassy with a percussive and snappy low end. Just the ticket for some Jimi, SRV or Los Lonely Boys. The bridge is wound to 7.8K but instead of just more wire, it’s also a lighter gauge wire. The net result is more output without the loss of clarity and detail typical of a higher output pickup (technically a higher resistance without a big jump in inductance). So you get more punch and better pedal performance without a big tonal sacrifice. Players who want to rock their Strat but won’t compromise on looks or authentic tones will like the Voodoo Blues SSS set.

 The Wrap

These pickups are not radically different from each other. It’s not like we were testing Hot Rails versus a vintage reproduction pickup. But in each case as we changed sets there was an “oh yeah, I can hear that” feeling as soon as we plugged in. We were not in total agreement on what we liked best either. My favorite set was the Tru 62’s while our new Sales Tech Eric liked the sweet-but-glassy tones of 54’s followed by the Voodoo SSS. For the moment, the Tru 62’s are staying in our Legacy, but the discussion is not over yet….

 

Vintage or Modern wiring for your G&L ASAT guitar?

Emerson vintage style Tele wiring kit with treble bypass

The Internet and blogosphere is full or articles and how-to’s on the differences of the so-called “vintage” versus “modern” wiring for guitars like the Telecaster® and Les Paul. So briefly, what is it and does it matter?

In short, in a typical two-knob volume and tone arrangement, the major characteristic of “vintage” wiring is that the tone capacitor (low pass filter) is wired between (connects) the volume and tone controls. On a “modern” circuit, the tone capacitor is connected from one lug of the tone control potentiometer to ground (usually the top of the tone pot). There are several variations on this theme, but in general terms this is the biggest distinction between vintage and modern.

Why Modern?

The modern tone control circuit allows for totally independent tone control regardless of where the volume control is set. Essentially, the tone control directly shunts high frequency single to ground, the amount depending on how much the tone knob is turned. In a modern four-knob setup (such as a Les Paul) the volume and tones controls are independent from each other and each pickup. In a true vintage Les Paul circuit, turning down one pickup all the way actually turns off both pickups (this can be remedied without changing how the capacitor is wired).

The characteristic of the modern circuit is that there tends to be a high end roll-off as the volume is turned down. This can be compensated by using a “treble bleed” or tone bypass circuit, which lets through a small amount of high frequencies no matter where the volume control is set. On G&L guitars there is a .001-microfarad bypass capacitor on the volume pot of every guitar. The capacitor acts as a high pass filter, and some treble bleed circuits use a capacitor/resistor combination.

Why Vintage?

In a vintage circuit the capacitor is connecting the volume and tone controls, and the signal going to the tone control passes through the tone capacitor first (in a modern circuit the full signal passes to the tone control before the filter capacitor is applied). As a result, the signal being fed to the tone control pot is dependent on the setting of the volume control.

The characteristic of vintage wiring is that there tends to be less high-end attenuation as the volume is turned down. Even without a bypass circuit, the volume control has little effect on tone. But the and volume controls are now interactive, and the tone control works differently depending on how the volume control is set.

Is One Better Than the Other?

The modern wiring setup provides independent operation, and with the addition of a treble bypass circuit the volume control is quite functional. On some guitars a little high-end reduction via the volume control may be desirable, but on a darker sounding guitar a volume control without a treble bypass may be all but useless.

With vintage wiring the volume control is usable – and possibly better sounding – without a treble bypass. But how the tone control works depends on where the volume control is set. To some this may be annoying, but I like the range of different sounds available via the interactive nature of the two controls. I also think the volume control plain works better too, and I prefer it without the bypass. On a two pickup four-knob guitar like a Les Paul, the vintage wiring setup allows a vast array of tones just not available with the modern wiring scheme.

I’m a vintage wiring proponent, but if you can solder it’s pretty easy to switch back and forth and see what arrangement are most comfortable with. There is no right answer, just options.

 

 

 

The Great American Guitar Show – Valley Forge PA, Day 1

gordon

We’re down here on the outskirts of Philadelphia for our first Great American Guitar Show in Valley Forge, PA. We came down Friday during the day in order to unload and get set up for the show on Saturday and Sunday.

While we have no way of actually knowing, there have got to be at least a couple thousand guitars here if not more. It’s surprising how much vintage stuff is on hand: Dozens of 50’s Les Pauls, 50’s and 60’s Strats, 50’s Teles, and enough vintage Les Paul Jr’s to make any Keith Urban fan jump for joy. I’m kind of LP Jr. Double Cutaway freak, and for between $4K and $9K I can have my pick of at least a dozen. The topper is a maple top burst 1960 Les Paul for $175K. Hmmm, house or guitar, house or guitar.

Action at the UpFront Guitars booth was pretty good, with a lot of people drawn to the Godin Icons, No-Top ASAT Special, and the ASAT Honeyburst Classic S. The Emerson pre-wired control assemblies were a popular item too, and of the pedals JHS drew the most attention. Our Clear Blue ASAT HB left the building, and I’ll eat my hat if somebody does not walk out with an Icon tomorrow.

Being a guitar show, most of the attention was focused on guitars, but the updated ValveTrain Trenton and Bennington amplifiers received many complements. The new Trenton with its larger cabinet, improved front end and tube rectifier was just stunning. Warm, sweet, with a nice bounce to each note, it was a real honey. It effortlessly developed great tone at low volumes, while the higher headroom Deluxe-inspired Bennington wanted to be opened up a little more than show decorum would permit. We’ll be taking a video on Sunday with the Trenton and our Angry Angus Tele. Michael from Cliff’s Guitars (Wilmington DE) is going to help us with the demo, as frankly after hearing him play we realized we should stick to selling.

Speaking of players, Joe Bonnamassa was also seen walking around the show, possibly looking for something to add to his already extensive collection.

If you are serious about guitars, and especially if you dig the vintage stuff, the Great American Guitar Show is a must-do.
