Savarez Corum Polished Bass Set, Standard Tension Red Card, .030 - .042, 500RH3star rating 5John MettlerDecember 23, 2009I recently purchased a new guitar from Gary Southwell and have been trying different string combinations to find the optimal sound for this instrument. The Savarez bass strings provide the depth of sound and the precision of attack that balance the natural bass resonance of this instrument.
