Instrument Engineering: Miranda's Travel Guitar

I'm from Barcelona. A couple of years ago I adquired a CFX-200 Nylon-String Guitar. The idea of this guitar was not bad. The same size than a classical guitar. I paid more than 1200€ at that time. ABSOLUTELY DECEIVED.
1)They say "Neck width at the nut 52.3mm". This is true but the separation of nylon strings at nut was 44mm, the same than the steel strings model, all along the fingerboard. In this way they can use the same pickup used in the steel strings model. People, I can swear that if you stronly practice scales a week on this strings separation, you will need later another week to readapt your fingers to the standard classical strings width. Terrible.
2)Plastics easily broken. I have spent a lot of superglue to repair few parts.
3)The level balance of the 6 strings because the bad quality pickup system was unable. Always string one sounded less than the rest.
4)The earphones amplifier is mono: if you like to play the guitar over a stereo song or backingtrack, everything sounds mixed on your head, guitar and auxiliar input.
5)The 9v battery clip is not a professional choice. Easily broken.

Because the above reasons:
I spent a lot of money in a good luthier to substitue the original bridge saddle and nut by the standard width ones. I added a stereo earphones amplifier. I changed the 9v clip by a more professional system. I made a new acrylic heel plate tto reveal the cutaway, using aluminium. And finally I spent a lot of glue and patiente to repair the broken parts. I can show pictures about all I have said.

You better adquire a Yamaha SLG 120. Much better for less than half the price.

In over ten years of making and selling Miranda we have had only one disgruntled buyer. Now, you have heard from him. The gentleman from Barcelona bought his guitar in 2007, a nylon-string CFX-200. I will address the specific issues that he raised.
First, there is no right or wrong separation of strings at the nut -- it is a personal choice. I like the separation we use and have had no other complaints about it. He claims that it is the same as on our steel-string model. It isn't, and to my knowledge he has never seen our steel-string model.
He claims that the we chose a string spacing on the nylon string-guitar so that we could use the same pickup as on the steel-string. In fact, we chose that pickup several years before we even thought about making steel-string guitars.
We have not had any other buyer claim that they had difficulty moving from the Miranda to their acoustic guitar, and we hear from our buyers a lot, as our Comments page demonstrates.
Regarding the acrylic side panels: Unfortunately, at one time, without informing us, our plastic fabricator switched bonding agents on some units. We did have reports of a disbond problem, and had to recall and repair parts for several buyers. We did so free of charge and we absorbed all shipping costs. Happily, that is years behind us.
The gentleman from Barcelona decided to make major modifications to the bridge, saddle, and pickup of the guitar, unaware of the purpose of our design. We cannot be responsible for the results.
Regarding the monaural headphone driver, our purpose for including a line-in function was to enable playing along with a prerecorded guitar track, to facilitate learning. At that time, no other travel guitar had that feature. Making the output monaural enabled us to squeeze the rest of the electronics onto a board that would fit into the electronics case. As no one else has made an issue of this, we had no reason to reconsider.
As to the "unprofessional" battery clip, never had a problem with it.
We are rightly proud of our instruments.
