In this workshop, we aim to equip the participants with theoretical and practical skills related to the aspects of capturing, controlling and processing the sound produced by the string instrument. The presented information is dedicated to electrical systems incorporated in string instruments, both electric and acoustic. The proposed goal of the workshop is to give the participant understanding about the electrical functioning of the instrument and the ability to modify it according to his or her tonal and practical preferences in an autonomous fashion. After the workshop, the participants will be able to understand how a pickup works and comprehend the differences between various types of pickups, as well as alter and increase the range of configurations between several pickups. Another very interesting point is the acquisition of the ability of identifying and understanding the relationship between common problems and their causes, as well as defining solutions to them.
The workshop is held in Guitar Rehab’s shop and will be presented in english. A portuguese colleague will assist in case there are any language issues.
