Re: Technical Genius Required !

Blast from the past!

Anyhow, this problem isn't a simple harmonic oscillator with a mass connected to spring. Instead it is a boundary value problem with a string oscillating with a fixed end (string clamps at the nut) and a non-rigid boundary (possibly elastic) on the trem end.

The spring constant (k) doesn't come into play because spring isn't compressed or stretched when playing, only when using the whammy...

Get someone else to disassemble one to take pictures and measurements (or just get them to send one in). Other than that.. that's about it.

Sorry I should have explained myself better.

When you want to buy something that you can only get in huge quantities ask the place who sells it if they have off-cuts first. If they don’t have any ask who they sell to and go further down the chain until you find a small machining shop.

You will probably find you only have to make one or two phone calls until you find someone who will sell a piece to you.

I have done this with other things (not bell brass) but I don’t see why it would be any different. A small machining company will make one of those blocks in 20-30 minutes. Usually they charge around £20 per hour so you should get the work done for around £10 + materials.

Yeah, they're great in my experience. And they'll get the product to you quickly, usually it takes only a couple of days, happy shopping.

Yes and Yes - OR - If you send me the ZR block I can make one - I would need
the see pics of it on the guitar before hand and then have the block for a
week or so.
Let me know!

I've been looking for a while now for something like your brass blocks that
would fit an Ibanez ZR trem. They're a great candidate for it since once you
take off the ZPS system you're left with a bunch of free space previously
taken up by the springs. Because of that design the sustain block is tiny.

I've tried, unsuccesfully to buy a block of brass to make my own, but
haven't had any luck. Would it be possible to buy a blank (IE Untapped)
brass block from yourselves, or to get a block made for the ZR construction?

Obviously, since I'm not in the US I can't supply him with the necessary things to get this done! Would it be possible to order the block through you as some sort of custom order?

Edit: Oh, and seeing as I'm in the market for a 7 string right now, does anyone know if the ZR7 block is the same as the ZR block?

As you use these blocks I wonder if you could confirm or deny a few things please ?

The following is assuming no ESP AA is installed.

Would someone fitting one of these blocks to a Jem with an Edge trem lose any trem travel ? Up or down and if so how much ? If you are not certain about this please could you provide the dimensions and I will try to measure it.

Do you notice the guitar going out of tune when leaning forward, backwards or moving the guitar off centre at all ?

When you say “Thickens” the tone could this also be described as darkening it ?

Have you or anyone else ever made a demo of this block working ? Perhaps a guitar fitted with a standard trem block, pluck the string then time it and then the same guitar, amp etc but with just the block changed (No ESPAA) and then perform the same test ? I really think this will help your sales more than anything else. If people can hear the difference and take note of just how much more sustain this block delivers then we won’t be seeing these sorts of threads on forums !!

As for the ESP Arming Adjuster I can instantly see the benefits of this. I would be very interested in one of these but there is no UK dealer.

Also do you sell those “Noiseless Tension Springs” with the polymer coating ?

Thanks.
I actually have tested guitars with just the brass block installed and then with the arming adjuster installed. Actually I do that test quite often as both components are part of my premium upgrade package that I offer for my clients that buy a Caparison guitar off me.

With regards to the blocks for the Ibanez models, I actually have the brass block along with the arming adjuster installed in all my Ibanez's (a Universe with a 7 string lo pro, a RG1880s with a lo-pro and an RG8670 with a Edge-Pro). I still have full trem movement.

As for noticing the pitch go up or down, it's exactly the same as the stock block. The arming adjuster fixes that pitch variance. The brass block is still prone to gavity.

When I say "thicken" I mean your tone gets a good boost in the mids and low mids. Same tone, just thicker and fuller sounding. The Arming Adjuster takes it to the next level.

As for the Goldo Backbox, I've tried it thinking that I could get the same thing as the arming adjuster for like half the price but while it does do a pretty good job, the Arming Adjuster is (in my opinion) better built and will work with any trem angle. The flat end with the built-in pad on the backbox is more a con than a pro since it seems to take away from the energy transfer. If you want the backbox or an Ibanez Backstop I have a couple that I'm getting rid of as they're totally useless to me.

In all honesty, getting the block and arming adjuster is by far the best value upgrade you can do to your guitar. As a guitar tech I've spent A LOT of money and tried virtually every product out there that could improve the tone on the guitar and these are the two I've settled with. I really don't see why it's hard for anyone to not spend $50-$60 to get either part (ESP AA or block upgrade) for the tonal upgrades.

All I want to know is roughly how many more seconds of sustain the block will give me over a standard block (all other things being equal) and does it restrict how far you can pull up on the whammy bar on a Jem ?

The Goeldo Backbox is a done deal, I can see the benefits of that. In fact that or the ESP arming adjuster, either one but I think the ESPAA is better made as it has a ball bearing on the end of the push rod.

Shame there are no UK dealers for any of these products, the poor consumer over here has to deal with importation tax (basically a fine for not buying from the EU), long distance communications and currency conversion !!!

Anyone know of any decent music shops in the UK that stock this sort of thing ?

Yeah, I PM'd him but I'd have to pay beforehand.... Priorities I guess, it's too bad I can't comment on the brass block, I'd like to try it and would definitely be flattered to be able to post my comments about it without having to pay for it. One thing I'll guarantee is that the goeldo backbox after being properly setup (pretty easy task to be honest) is worth every penny. Maybe if everyone interested pitched in, myself included I'd give it a go. Let me know if you can get some guys willing to adventure in this, it's not that expensive but if your a 'family guy' things become different.

Kindest regards to this awesome forum,
Nelson

I'd love to test this, my guitar is up for a fret dressing that I'm gonna perform myself, he,he... and it would be the right time to fit my trem with one of these...

P.S. I have a goeldo backbox and it did make a big difference with regards to sustain and tone definition
