Re: The Hossenfeffer Bass

That looks great! I own two '73 4001 basses. One was my first good bass I got new at age 15. I was a big Yes and McCartney fan. I made an aluminum nut for my Rick.

Re: Which Pot for Active EMG?

I have found that the older EMG pickups (not the X series) actually sound better with 100k pots. They had more presence. The reason is that the output impedance of the original series of pickups is a bit on the high side (about 150k). So you get less loading with the higher value pot. On a passive i...

Re: how to mix graphite powder to get shielding paint

the best thing to do as a graphite expert is to use a mixture of isopropyl alcohol and graphite powder (be sure the powder is truly powder) spray this on and then follow that after it dries with a coat of shellac thinned a bit with denatured,they both use the same airborne finish to dry.must be spr...

Re: Noobish Confusion on Shielding

You do not need to shield the pickup cavities, as these pickups are internally shielded. But since you did add foil, just make sure it's all grounded.

Re: Pete Halliday's Latest Noisemakers

I had never seen the Marauder before. That's interesting that Gibson was also making something that was kind of Tele-ish. Do you know what the scale length was on those? It was a Bill Lawrence design. It looks like a flat top Les Paul, same as gthe L6-S and Sonex, with a maple or rosewood fingerboa...

Re: Odd Gstring sounds

How high are the saddles set on the bridge? I used to use those, and one problem is if the saddles are not high enough, the string buzzes on the roller, and sometimes pops out. Schaller supplies spacers with the bridges, but I've never found a reason to use them. They often put the bridge too high, ...

Re: Guitar tuned in fifths research

I'm familiar with Fripps tuning (NST). I've wondered why he is exploring different tunings one the one hand, put kept on using a standard guitar (with parallel frets) on the other, but maybe he just didn't came across the multi-scale concept (although it has his history). Well Fripp came up with th...

Re: vari tone in a box

Varitone circuits are notch filters that cut out the midrange. If you remove the inductor, then they are decade controls that cut out the high frequencies. Some instruments, like the L6-S guitar and L9-S Ripper bass, used a potentiometer as a midrange control, instead of the rotary switch with the a...

Re: hand wound pickup question

Okay. when i peeled wire coating off of coil harness i found that the wires for coil tap had touched against the shielding copper. That's why I figured blown. So I removed the shielded wire bundle down to just the 4 short wires coming out of the coil, I tested there. 1 showed continuity. Nothing on...

Re: New (approx) 1 watt amp

And roadies with back injuries! A 100W amp is only 4 times as loud as a 1W, using the same speakers. And most cheaper instrument speakers have poor efficiency. A nice 30W guitar speaker with 113dB 1W/1m with a 1W amp is plenty gigging loud! Only if all you want is distortion! I have a nice little V...

Re: how do they construct a hum canceled p-90?

The Frailin pickups are sidewinders, like the old Lawrence L-250s. In a sidewinder the two coils lay on their side with the tops facing the keeper/pole pieces. This way there is a single point in which the pickup samples the string, and it sounds like a single coil. They are a little less efficient,...

Re: Alembic P-Bass pickup w/ no preamp

I still think even the bass/treble preamp for the Activators is going to be way over priced. Oh and the Series I and II electronics are like $3,000. The Activator preamp is one op amp and a few other parts. This is the low pass filter module. http://www.sgd-lutherie.com/images/Alembic_Activator_prea...

Re: Mario Labonte's Jazz bass build

Are those deeply notched bridges part of the design of the bridge? That's a Badass I bridge. It was intended for Gibson basses so it's very high. The notches should not be cut that deep! Half of the string's diameter is the general rule. The Badass II bridge is made for Fenders and is a lower profi...
