I was watching the Steve Morse Rig Rundown at Premiere Guitar.  Steve stated that he uses the Neck pickup to solo in the higher pitches, so it isn’t as sharp on a person’s eardrums.  I’d never really thought of it in that way and not used it in that way very often.  So, I tried it out repeatedly.

I had just a few thoughts come to mind regarding modifying amps, modifying EQ, or creating your own.

It’s a fact that Mesa Engineering uses two modified forms of the Marshall tone stack for their Dual Rectifier series.  Compared to a classic Marshall tone stack, the Vintage/Raw tone stack moves the center of the “Mid” control down in frequency and has more attenuation.  This carves out some of the meatier part of the guitar frequency to make room for the massive lows and a high-mid emphasis.  The tone stack enabled for Channel 3 Modern has boosted upper-mids, but has a very similar, low-to-low-mid frequency response.

I put together a rudimentary representation of the effect on filter curves when setting a graphic EQ.  It isn’t exact.  Use it to get a general idea for the way a graphic EQ shapes the signal. (more…)

Using an equalizer to boost the guitar’s input signal makes a lot of sense.  It provides a clean gain and a lot of headroom.  Aside from boosting the signal, it can, of course, be used to carve out specific frequencies.  Unlike most overdrive pedals, an equalizer has the ability to be very precise with multiple frequency bands and can create special effects.

The downside to this specific pedal is noise.  It uses cheap tantalum capacitors in the signal path.  This creates a hissing sound when the sliders are moved away from the zero mark.  The MXR 10 Band EQ is reputedly better, but I don’t own it and can’t comment about it further. (more…)

On the back of every Mesa Engineering Dual Rectifier, there are 2 switches to select options for the power supply.  One of these is to select Bold and Spongy and affect overall voltage to the amplifier, with Bold being full power and Spongy reducing power by about 20%.  The other switch is used to select the rectification: Silicon or Tube.  Selecting Tube reduces power by nearly 10%, since the tube has losses when it conducts.  There are 4 options for running the power supply:

  • Bold and Silicon
  • Bold and Tube
  • Spongy and Silicon
  • Spongy and Tube

Before I get to decisions for selecting power supply options, we should cover some facts and history.  Along the way, we’ll learn basic information about the differences between these options. (more…)

I occasionally re-read my blog articles and wonder if I was hallucinating in a fever dream while typing poorly translated incantations.  It looks like words arranged into sentences, but it doesn’t make a lot of sense.  I’ve been updating some of them so they aren’t as confusing, or, in some cases, so they actually make sense.

The truth is that I often write while having morning coffee.  Perhaps I should wait until after morning coffee?

There’s a Goth band name: Mourning Coughy.  Or, Mourning Coffin.  heh.  So dumb.

I previously wrote about my trials of playing guitar while dealing with a serious illness.  With my 25.5″ scale length, LTD guitar, I’ve now found a medium point of balance.  When I am able to play, the guitar nearly plays itself.

After more than a decade of doing my own setups, I’d stopped measuring them and would do it mostly by feel.  I did it that way for years.  For the problems I have now, I need to be able to easily adjust anything if the guitar shifts from temperature or humidity changes.

At the time of the previous article, I had been thinking in very abstract terms regarding tension and height; trying to imagine the physics at work.  What I’ve ultimately found is that I’d made the height so low and relief so flat, the neck did begin to backbow and warp.  I corrected the truss rod, increased the tuning, and set the guitar aside to settle in.  When I came back to it, it got a setup similar to the factory specs and then some adjustments were made.

Awhile back, I found this page while doing research for building effects pedals or amplifiers.  Jack Orman has some really great information and ideas on his site for many different circuits, modifications, and adaptations.  I’ve found it to be quite inspiring and I encourage anyone who is interested in guitar or effects technology to check out his site.
