Construction of AV Basses

The AV Basses instruments are available in these scales: 32, 34, 35 and 36 " and multiscale, that is instruments  with changing scale due to  fanned frets.

The structure of the instrument can basically fall into one of the two categories: with bolt on neck or neck through body (or glued in neck).

Both these methods of creating an instrument have their advantages and disadvantages. A neck-through instrument has higher demands on construction and materials. Choosing the way the neck is attached to the bass is one of the fundamental decision when choosing the right instrument. 

These are the two basic methods of attaching the neck to the body and they can, of course, be further modified. Bolt-on-necks can also be glued or set into the body which would be a compromise between the two ways. The neck could be the body of the instrument (it is then called a deep set neck), and still it could be secured by bolts.  

In this way, a really comfortable access all the way to the to higher positions at end of the frettboard can be achieved. In terms of access to higher positions, the attachment is then similar to the neck-through-body instruments.

A neck with bolts can be attached to the instrument body by four to six (or even more) bolts  and ensures firm and sharp, almost hard sound of the instrument. 

Sustain is of good quality, but a neck-through instrument has a longer sustain and more spread out sound. We can talk about faster entrance of the sound in bolt-on-neck instruments, but the tone also “fades out” faster. 

A neck-through instrument has higher demands on construction and materials. Neck through body can be utilized especially in fretless basses.

The neck through body can also be glued directly to the sides of the body. In this way the neck remains visible and adds visual appeal to the instrument, as it goes through the whole instrument.

For example, a compact whole can be produced from a neck of seven parts and a top board and a back board.

We can produce an instrument with high total strength, which also influences the definition of the instrument’s sound. 

Each type of wood in the total lamination leaves its trace on the final sound of the instrument.

As a matter of course, we add a headstock plate made of wood matching with the instrument body.
