Hi! Firstly, my sincere apologies at posting in the wrong section. Hopefully this will be moved for me, for some reason it wont let me post in the classified ads section. I am looking for a four valve compensating block, from the leadpipe all the way through to the main tuning slide from a BBb Bass at a fairly cheap price. This is probably more targetted at repairmen or collectors/sellers who have spare parts available. Is there anything out there? I am not really interested in the main body of the instrument, although, if the price was right, i may consider buying a whole instrument. I have no model/make of preference as long as it works, although stuck slides arent an issue. What you got?
