I am a beginner LH bass player. I bought a Johnson (by AXL) p-bass off craigslist for $100. At the time I bought it I didn't care about the tone, action , etc because I figured I would dump it for something better if I stuck with it and enjoyed playing. Fortunately the thing stays in tune, the neck is straight, and the frets have stayed in place. I really don't have any complaints about it for what I paid for it. I can't find much info on Johnson or AXL instruments but I have discovered through the interwebs that some off brands can be decent, like SX. Does anyone have experience with Johnson basses, and if so are they built well enough that it would be worth another $75 to put in a Quarter Pounder pickup or should I leave it as is and save the $75 towards a better bass?
