Here’s an email I received from a satisfied client of mine that recently did a tone make0ver on his 4×12 cabinet. He was pleasantly surprised with the results and I wanted to share them with all of you.

Please leave your comments or questions below.
===================================

Hi Bob,

My name is Joey, and I just recently discovered your Marshall 4×12 setup video. Thank you so much.  I not only ADORE the sound I am getting out of the cabs now, I loved the hell out of performing the surgery.

My 2 cabs were very new and every screw needed tightening, center braces off center, and one actually had less than 18AWG in it.

I never imagined I’d be the one to fix them up but thanks to your inspiration, I did

Nice silicon caulk beads, re-wired both with 18AWG, resoldered all connections (No more clips). Center brace remounted to front (Removed staples and replaced with 1″ dry wall screws and wood glue to boot.
I also centered the post without drilling a new hole.  I set the back plate on askew by 45 degrees, guided the center screw into my pre-tapped centered post hole, tightened with a couple turns, then repositioned the back plate correctly, then tightened the center screw down the rest of the way.

My bottom end is marvelous

All this improvement has inspired some curiosity.
What would a 2×4 for a center brace do for my sound?

What kind of sound change would replacing the 4 GT12-75s with V30s?

Thanks again Bob, you’re a Peach!

Thanks Joey for the feedback!
I wanted to answer your questions.

What would a 2×4 for a center brace do for my sound?

Answer: We’ll that’s actually a good question and I’m glad you asked.
The more mass you have in between the front baffle and the back panel will
definitely change the focus of the sound. It should actually be a bit more aggressive
and tighter. You’ll notice a difference in the  response, and sound pressure level.

IMPORTANT: if you do this is critical that you make sure the length is the same as the
original post. It needs to be slightly longer to create the force against the back panel.
I hope this helps.

Question: What kind of sound change would replacing the 4 GT12-75s with V30s?

Answer: Another really good question. The GT 12-75’s are actually good all around
speakers for a balanced low end and a balanced top end, however if you like a really
focused mid-range sound with a punchy tight low end, the Vintage 30’s are the way to go.
I’ve used both for years and can say that the GT 12-75’s tend to get a bit saggy on the bottom
and lose the character at high volumes. The Vintage 30’s really project accurately at high
volume levels. The vintage 30-H is recommended, Or the Van Halen Vintage celestions.

Just hangin out with my long-time friend Dj Ashba. It’s always good to catch up with him when we can, as he’s extremely busy with his band Sixx A.M. as well as his media company. I’m really looking forward to checking out his new signature model Ovation Guitar. He’s got 4 different models designed to his specifications. I’ll be able to check it out thoroughly at the NAMM show in January out in L.A.

Myself, Gary Horrie, Cody Barra, and Dirk McCoy are all going to 2009 NAMM show in L.A. to support the UNK Guitar Release. We’ll also be playing a Powerhouse set with Andy Lee in Support of Carina Lirola’s debut album on Steve Vai’s Label.

The show is supported by UNK guitars and is on the same bill with George Lynch. I’ll be shooting footage from the shows, and doing several interviews as well. I’ll keep you posted on all the developments as well as reporting on the latest gear from NAMM.

More Later…

Guitar Tube – Tube Amp Power Tube Reissue Vs. Vintage

Vacuum tube amplifiers are some of the most sought after amps in the industry
due to their warm rich tones. For years people have compared certain types of
amp tubes for their sonic richness and warmth. More than that, it seems to be
the older vintage models that win most guitarists over for their great guitar tone.
The big problem usually occurs when trying to find new oldstock tubes, or at least
tube that may be similar in it’s characteristics.

In this article we are going to look at the KT66 power tube. This well respected
tube was introduced in the mid 1950’s by the Marconi-OsramValve Company. They
marketed their tubes under the name of “Genalex”. The KT66 was Europe’s
version of the American 6L6GC.

The KT66 tube is quite larger than the 6L6 in physical size. It also has quite
a big sound to go along with it’s size. The tube was used in the famous Marshall
Bluesbreaker Combo in 1965 – 1966. Marshall eventually changed to the more readily
available EL34.

If you’re lucky enough to find an original new old stock matched pair of KT66
tubes, you should be prepared to pay around $600.00. This is the current cost
of these “original” bad boys.

On the other hand, you can get a matched pair of the reissue Genalex KT66 tubes
for a much more affordable price of $99.00. These reissue tubes duplicate the
large clear bottle of the UK tube, as well as it’s brown base, gold-ink lettering
with prancing lion logo, gold plated screen, and huge plate structure.

 

The comparison between the original and the reissue are as follows:

 

 

• The early original KT66 tubes sounded big and brawny, with extended lows
  and a very rich and detailed set of mids and highs. Something all guitar players
  tend to look for in a quality tube.

 

• The reissiue Genalex KT66 tubes sounds incredibly similar to the original.
  They deliver an almost identical sense of presentation and focus. They didn’t
  seem to drift into the dreaded saggy zone when pushed into distortion. As
  with the original tubes, the reissues KT66’s overdrive voice is throatier
  and more british-sounding than the 6L6’s, and they respond beautifully to
  the changes in picking and volume dynamics.

 

 

It’s very easy to see why this robust-sounding tube remains so popular with
savvy musicians. With such a great-sounding reissue tube available at only a
fraction of the cost of the originals, it’s an attractive replacement for any
6L6 amp that has enough cabinet space to accommodate the KT66’s tall bottle.

As far as long-term reliability of the reissue, it’s hard to say for sure because
the superbly made original is a tough act to follow in that regard. However,
if you’re interested in getting great guitar tone with the highly acclaimed
KT66 power tube, the reissue Genalexmodel really hits the mark.

I hope this has helped shed light on the highly acclaimed KT66 power tube.

Guitar Tone Using Pedal Effects
within a Multi Pedal Board

(PART 1 of 2)

Have you ever thought about building your own pedal effects board? Have you
actually built a pedal effects board only to discover that your guitar tone
has changed drastically? Believe me, you are not the first to run across this
problem. In fact the majority of pedal effects boards will change your tone,
and most of the time is it not for the better.

There are many things to consider when designing and building your pedal board.
If you’re careful to address critical issues during this process you’ll end
up with a great guitar tone. If you’re not careful you may end up with a guitar
tone that is less than desirable.

Here’s a few things that will affect your guitar tone when designing your pedal
board.

• Length of Cables
• Types of Cables
• True Bypass
• Buffering
• Unity Gain Structure

There are more things than this to examine in Part 2, but for now this will
get you on the right track to killer guitar tone when designing your effects
pedal board.

1. Length of cables - You should try to keep the length of
   your cables as short as possible. This includes the patch cables in between
   the pedals as well. The reason is that the longer your cables are, the more
   tone loss, gain loss, and high end loss occurs.
2. Types of cables - Just as the length of your cables can
   result in tone loss, so can the type of cables. This is something that is
   sort of a personal preference, but I will say that Mogami and Belden cables
   are always going to be a great choice. Keep in mind that the most important
   cable is the first cable used from your guitar to the first effects pedal.
3. True bypass - This can be good and bad depending on the
   rest of the pedals in the chain. If all of your pedals are true bypass, and
   they’re all turned off, you face the problem of all of your cable lengths
   adding up to one long cable going into the front of your amp. This is really
   bad if you are using vintage pickups with low output and high impedance. You
   should consider some type of buffer to keep the signal steady.
4. Buffering - Buffering the signal can help when using true
   bypass pedals along with vintage pickups, but you’ll have to play around with
   the combinations. You may run into issues of signal spikes and treble spikes
   depending on where the buffers are placed in the chain. Best solution is to
   plug your guitar directly into a fixed high-impedance load that is identical
   to the amp input. Then distribute the signal to the various effects and amps
   by low-impedance buffered feeds. This will give you constant signal level,
   and tone characteristics, which will not change when more effects are added.
5. Unity Gain Structure – This is another critical issue when
   it come to balancing out your sound. Example: if you used
   a chorus pedal and a delay pedal these devices are usually unity gain. When
   you get into pre-amps, equalizers and units with gain control, you’ll need
   to balance all of them out so that one unit is not louder that the other when
   turned on or off.

Hopefully this will give you some great insight when building your personal
guitar effects pedal board. If you carefully design and construct your pedal
board, your pedal effects will sound great every time you plug in for years
and years to come.
