We have some excellent professional 120 Bass models in stock. Tuning depends on the type of music you play so we have a choice of straight and musette to cover all tastes. In addition, we can supply instruments fitted with MIDI and internal mics for band/stage performers. These are amongst the most expensive accordions to buy so our quality used models offer considerable savings on the new price. Visit the Accordion Pictures/Prices page for our full range.
