Bass Ten Long

ToneStyler - Bass Ten Long -

A BASS DUO SIX is required when retaining the traditional three-knob "volume-volume-tone" control plan. A popular alternative is to convert the dual volume controls to a master volume plus a mono blend pot. This circuit change allows an upgrade with a BASS SIX or TEN, and reduced component costs. However, tech time is increased when installing a blend pot, which may reduce your savings in parts.

After converting your dual volumes to a master + blend, choose the Bass SIX for casual and stage use; choose the Bass TEN for its extended EQ range and increased fine-tuning, valuable for studio use.
