So difficult to describe. I bought a new Englehardt M-1 this summer. I played it first, then bought it. I didn't know that it sounded so crappy until I went to a few festivals and played a few other basses. My bass has a "choked" sound, something like the strings are dampened or muted. I played a few old Kays, and even a few Chinese made that have a much fuller "blooming" tone, with more of an open sustain. I have tried a few "improvements" without much success yet. So far, I've replaced the tail piece "bracket" with a flexible wire, & put on set of Spirocore light gauge. Both of these changes made some difference in tone / volume, but only a slight improvement. I lowered the action some by removing some of the top of the bridge, but this did nothing other than improve playability. People tell me the sound may improve over time with playing & vibration. Are there any suggestions out there for the next step? These old basses I've played at festivals that sound so warm, full, open, and loud are all old, and many have had supernils or something similar. My bridge seems to fit quite well, so I'm at a loss of where to turn next. Suggestions please!?!?!?!
