My new ESP LTD GB-4. It has a pair of Seymour Duncan SSB4 humbuckers, as well as an SD STC-3M3 3 band EQ. The EQ also has a switch to contour the EQ for slap, which is implemented on the bass as a push/pull switch on the volume.
When I got the bass it had two issues. First issue, treble knob is sticky for part of the rotation. Doesn’t seem to have any effect on function.
Second problem, which I am trying to understand. I got the bass, and checked it out. Tuned it, intonation, setup, usual stuff. Played it a bit, and then tested the electronics. Set everything to zero.
Turned the bass all the way up. Check.
Turned the mids all the way up. Check.
Turned the treble all the way up, no change.
Changed the battery, no effect.
Took the cover off, checked the connections, all seemed solid. Checked the switches on the EQ (I can adjust the countour of the slap function), put it back together, everything is as I found it.
Picked up the bass tonight to play, because its a really sweet bass. Went through the process again, this time engaging the push/pull switch
Bass knob check.
Mids knob check.
Treble knob - check!
Pushed the volume back in, treble knob, still works. Something I did fixed it. Either the switch on the EQ, which I put back and is only supposed to effect the slap contour, or turning on the slap function.
So I have a perfectly functioning GB-4, except the sticky treble knob. And I don’t know why it works.
Observation - LTD quality is sooo much superior to Fender, Squier, or Ibanez. Opening up the cavity, the wires are much neater and have ties on them. Soldering is really well done. The cover has a layer of metal tape on it, and the shielding paint is well applied. Intonation was spot on.
LTD does a nice job. The fingerboard also feels great. It’s Pau Ferro, and I was not a fan of it on my Player Jazz, but it feels much nicer here. The bridge is much nicer, a Gotoh, than other basses except the SRMS805. Nut is 38mm. It’s light. I really like this bass.
Certainly will keep ESP in mind. I am a fan now.
