About This Listing

Dieter Hopf – one of the most innovative guitar builders of all times – made this invention around 1980.  With two patented features:  f.v.t.s. (Free Vibrating Top System) and extra sound holes in the bridge.

When I found this guitar in 2018 the bridge looked as in picture 17 – 19.   I was confused and wasn't able to find any answers online.   So I wrote to Dieter Hopf – at that time at the age of 82 and still going strong !  And very kindly he sent me a letter containing a picture and a description of a similar model Classic II f.v.t.s. + two grids to put in the holes, that I then re-created.

This model named CARTAGENA f.v.t.s. is the former model offered by Willy Hopf & Co. – where Dieter was responsible for the guitar making.

Mensur 650 mm.   Nut width 52 mm.  Action 2.2 mm❗️ Body frequency between C and Db.  With Knobloch CX 300 ADC strings.

It has a great magic tone even by gentle / soft playing – and has a few superficial inperfections.

Prepared for electric amplification:  The jack adapter at the bottom.

The YouTube video is showing another model with the same Free Vibration Top System and bridge sound holes.
