Fretless guitar Scarab AL - description

After Arli contacted me with his request for unfretted fingerboard guitar, I decided to rework the original design of a small body Scarab model. I enlarged body and changed the shape of a horn extension. Also the shape of cutout below its neck was modified. Large body delivers more wood resonance and provides more space for spreading control knobs. Another change was made to the headstock shape. Tuners are placed in positions now, where each string comes straight through nut slots without bending to the side.Overall style remained and functionality was improved.

There are another modifications which has been made to change sound character and adapt playability for particular guitarist. Body is two millimeters thicker, which makes it more resonant. Thickness of the neck has been reduced to possible minimum of 20mm. A six positional Freeway switch replaced standard three way toggle to multiply electric circuit options without using additional knobs. It is quite hard to say that sound of this guitar is somehow better than the sound of the previous Scarab version. These modifications has been made to improve guitar on its playability on the stage, to make better access to controls and more importantly to change its sound character. That's way there is fitted Alternative 8 bridge humbucker to keep guitar sounds warm with additional clarity. Designing of this guitar was a challenge to me. Arli uses an E-bow and plays modern music with influence of traditional Middle Eastern styles. A fretless instrument is the right choice for a skilled guitarist with such a style orientation. I created a brand new charismatic instrument for him.

This guitar has two humbuckers which can be played in standard series mode or single coils only. They can be switched to parallel mode and played individually or together. Single coil of each humbucker can sounds together with the second full humbucker in both modes. Switching between these modes delivers thirteen different unscreened sounds. Each of these sounds can be smoothly modified by linear potentiometers. Tone controls are separated for each pickup and fitted with a push/push switches for changing two capacitor values.

Even if this guitar was design especially for one guitarist, its character is not aimed at particular music style or tonal character. It is versatile and can be made again with frets or without. It has a remarkable natural sustain and lot of harmonic. High output pickups recognize muted sound of pressed strings on the unfretted fingerboard. Playability is perfect as well the weight position on the strap.

At the end something about its design. There is nothing what I would change on this guitar, nothing to add or remove. I would be happy to make it again and to delight another good musician.
