General Discussion / Where are they now.
« on: January 26, 2016, 02:10:56 PM »
Back in 2006. Matt O'ree, won the GC KOTB contest, beating out a true bluesmen Gino.  Now getting back to his blues roots, Matt O'ree is now touring with Bon Jovi


I was pointed toward this today:
Fact, but with caveats.

Internet wisdom states that no two amps of the same type sound the same. That is true, but the reasons are far more simple than many would have you believe. Tales abound of esoteric effects such as wire dress, transformer orientation, phase of the moon, etc. And while these do have some effect, it is arguably inconsequential relative to the single biggest source of deviation: tone control tolerance.

I've spent the last ten years modeling tube amps and the number one thing I see is that tone controls are very inconsistent devices. First of all the tolerance of the control is typically 20%. That's plus or minus 20% so 40% total. A 100K pot can be as low as 80K or as high as 120K. This is contrast to the tolerance of a typical passive component which is 5% or less (usually much less IME).

Secondly the resistance at the midpoint can vary widely. A Log10A pot should be 10% of the resistance at midpoint. But, again, this can be off 20%.

Let's take the case of a bass control which is typically wired as a rheostat. On one amp the pot might be 10% high and the midpoint 10% high. Therefore with the control at noon (assuming, say, a 1M pot) the resistance will be 121K. Another amp off the assembly line might be 10% low. Therefore the pot will be 81K. That's a 40K difference between the two amps and that's not even worst-case.

Now you can make the amps sound the same by simply turning down the control on one and/or turning it up on the other.

So when your friend says "well, no two amps sound the same" you can explain to him that they are probably more similar than not and a small twist of the tone controls will bring them into agreement.

I have to disagree on so many levels.  I doubt I can make my Mesa sound like Brad's victoria, nor can BH make whatever he plays sound like my old silverface just by tweaking a tone knob.


Guitars / About there...

For the first time in 10 years I own less than 10 electric guitars. 

Was about to sell my classical guitar until the bridge came unglued yesterday.   Going to have to pay to fix it before it gets sold.  That was sad. 

Guitars / ok, this might be a stupid question, but I am asking anyways.

I am trying to sell my SG and have had an offer for partial trade.  It is a crappy Ibanez acoustic that should sell for about $200.  He claims he took it somewhere and "Had it strobed" so it is now worth at least #500.  I have never heard that other than using a strobe tuner. 

The guy then proceeds to tell me that it cost him $300 to have his guitar "Strobed" and he says it plays better and sounds better after this "Strobe" thing. 

Can't find anything on line and have never heard of anything like this before.

thoughts?  Is this guy stupid, trying to rip me of, been ripped of, or otherwise.

Guitars / A primer on guitar repair.

Below is the official primer of Burlap and Blues on how to repair guitars.

Acoustic Guitar Bridge gluing

This week I was contacted and was asked if I want a 1978-1979 Ibanez  MC-500ds for a few hundred to help a guy make ends meet. 

The original had a 3 band active EQ system (aka. trying to be an Alembic copy) split coil, out of phase coil system.   Sounds like it would be a great recording instrument.  Heavy as 2 Les Pauls, and explorer and SG all put together, but tone and sustain for weeks.

Well, it had a few mods.

New unkown pickups (humbuckers) + routing.   *The bridge sounds great, but the neck is somewhat microphonic. 
Removal of tone and wired only mail volume.
Routed and mounted pre-GK-1 synth pickup (that no longer works). 

Other than that in fair players condition.  Would make an excellent guitar for recording if it was reconstructed and set up right.  As it is now, it looks like it has been toured (and the original aluminum flight case) shows it has toured.   Needs a decent cleaning and set up with some strings that have been made in this century.

Thinking about putting a set of P-rails in it and a current synth pickup or just holding on and reselling after the first of the year.  In the condition it is in now it is at least a $200 gain and due to the routing original pickups will be out of the question.   

Very resonant instrument and has been around the world a few times *and it shows.

better pictures forthcoming

I have been consistently using a JHS EHX soul food.  A very good Klon Klone.  Up until November 22.  During playing it farted out.   Started making fart noises when on.  The thing is totally dead.

So I sent a message to get it repaired after reviewing the warranty:

"Our pedals carry a Limited Lifetime Warranty (for as long as we are in business) for ANY problem related to the function or operation of that pedal due to faulty parts and/or other internal problem.  We do not cover things such as broken knobs, pots and jacks due to abuse.  We build them to last but not to be thrown out of an airplane. However, we will repair problems that are out from under our warranty like the above at a very reasonable price.  Several of our pedals have internal trim pots which are set and sealed very carefully for the function of the circuit and it should be noted that tampering with the trim pots will void the warranty.'

So, I baby my equipment. 

The first response was annoying.  "Sure send it back, it will be somewhere around $45 to fix it and then shipping back."  That's half of the cost of it and I guess that simple failure is excluded somewhere.

The responses from there get worse.  I guess they get to make any kind of change to their warranty whenever the heck they want to.

Nice warm drummers stool. I am pretty sure this is from the guy that has been placing the double drum beater for the past 15 months. Smile and have a great day.

hosted an outside jam yesterday at the lake.  Went well.  Had to buy and then haul a generator.  It was stupid fun, everyone had a blast.  Ended up with 7 groups playing and then at the end everyone got up and played 2 songs together.

  sunset was stellar

played with the fog machine a tad too much but it was fun.
