Is it the Classic IV Pro you have (Through neck)?Any good/great budget upgrades I can do to a standard Epiphone TBird IV? It's a great bass, but I want to make it even better.
If so there isn't a huge amount you can do, sort of a list for starters, others will chime in but it's a nice bass straight out of the box
Change the nut to a nice bone or brass one
Set it up
Chrome it up (can tell you how) and put in Hipshot HB6 LIC tuners
Bridge change (not for me unless to chrome as part of above)
Straplocks
When I first put on new strings I tune 'em F-Bb-Eb-Ab to "stretch" them. Couple of hours later they're just about right.
