Hi, it's the 65th anniversary of BB king's Lucille Gibson and there is a reissue in the store ATM.
I just figured out the varitone selector : it's a notch filter and I could find some specs :
Position 2 = C1 - softer than bypass
Position 3 = C2 - deeper tone than bypass, better response
Position 4 = C3 - jazz box full
Position 5 = C4 - jazz box mellow
Position 6 = C5 -almost woman-ish tone
Position 1 : Bypass
Position 2: 5db sur 1950Hz
Position 3: 12db sur 1100Hz
Position 4: 16db sur 620Hz
Position 5: 18.5db sur 360Hz
Position 6: 21db sur 120HZ
bullet Position 1 : Bypass (no effect)
bullet Position 2 : -5dB at f0=1875 Hz
bullet Position 3 : -6dB at f0=1090 Hz
bullet Position 4 : -7dB at f0=650 Hz
bullet Position 5 : -10dB at f0=350 Hz
bullet Position 6 : -14dB at f0=130 Hz
So I did tweak my KPA in order to have 5 studio eq presets set as the specs , the last one being post EQ since there is only 4 slots pre eq (it's even better post EQ ) ... I did compensate all 5 presets volume changes on EQ volume.
Here is the result : BB KING's Lucille SIM rig - Check the rig exchange . It's based on the great great 66 fender vibrochamp by Simon B and with my open back 2x10 JTM cab. I did choose this amp & cab since the whole gain range responds fantastically to your play.
Be sure to engage ONE preset at a time, but you can get some interesting results with two engaged. EQ presets are in reverse order , but more logical order : from low to mids .
Adjust Gain and Volume at will , it's set up at breakup on the actual rig, just lower gain and you'll find BB king's clean tone easily
The beauty of this rig it's that it will even work on single coils and P90, I did test with PAFs, p90, SC and on Hollow bodies and it sounds great.
I had to make some means since I had two different EQ specs & I did some slight adjustments to the EQ specs , they sounded more musical to me ( %mix and dB range )
