I have been having a couple of issues with my bass recently and would like to send my horn to get fixed. I would normally take it up to Dillons to be fixed but I cannot take the time to do so for at least 2 months. What are some places to do so around Philadelphia?

Issues being linkage heads are worn out, slow tuning slides, and I would like a general cleaning done.
