Device

Iyo nhanhatu-tambo gitare yehama dzeDoper yakasarudzika nekuvapo kwealuminium cone-diffuser mukati memuviri, pamwe nezvimwe zvinhu zvechishandiso:

• mutsipa unogona kuva wenguva dzose kana mativi ane tambo dzakakwirira;
• humbo dzose dzechiridzwa simbi;
• pane nguva dzose maburi maviri pamuviri pamativi ose emutsipa;
• kureba anenge 1 mita;
• imba yakasanganiswa nehuni nepurasitiki kana simbi zvachose;
• nhamba ye resonators kubva pa1 kusvika ku5.

Acoustic properties yakafadza vaimbi. Chigadzirwa chitsva chine timbre inoratidzika, ruzha rwave rukuru. Mugadziri akaisa chivharo chesimbi chine maburi pamusoro pedeki. Iyo haingokwidzi ruzha chete, asiwo inoita kuti bass inzwike yakajeka uye yakapfuma.

nyaya

Resonator magitare anotungidzwa kubva patambo yechitanhatu. Zvichienderana nematambiro ekutamba, vhura kana slide chiito chinoshandiswa. Open high inoshandiswa munyika uye blues. Muchirongwa ichi, tambo mbiri dzepamusoro dzinorira mu "sol" uye "si" - GBDGBD, uye muOpen low 6th uye 5th tambo dzinoenderana neruzha rwe "re" uye "sol".
