Hi! Eversince I started to play bass that I always dreamed of having a Rickenbaker. Thing is that I don't have 2000€ to spend on a new one and the the ones sold in the second hand market are also over my current budget. I've looking at some chinese copies at aliexpress.com that look really nice and that come with mahogany or ash bodies and have the option of rosewood or maple scale. I know that these basses are not the real deal, but I have two questions about them to help me clear things up in my mind. Are they playable? Do they sound any good? What type of upgrades and mods are suitable to make them better?
