Michael Rath slides are available in three different materials for the outer slide – yellow brass, bronze and nickel silver.
A nickel silver slide allows a more articulate, brighter sound than yellow brass or bronze and it can also feel more open on some component combinations. A bronze slide typically sounds darker and feels more centred. Bronze can be an excellent choice, for the R4 or R9 models, for a player searching for a dark, symphonic sound. Yellow brass slides sit in between nickel silver and bronze in terms of their tonal characteristics and feel.
