Bass Cut (ES 345 and Lucilly Varitone) for a Les Paul

Varitone or Bass cut - mod, lets cut some basses off (customized for a Les Paul)

Hello friends, now I became curious about the varitone circuit (bass cut circuit) used in the gibson ES 345, and decide to try a shot. After a lot of searching for the circuit at internet, I started making experiences in a les paul with a old pickup as the inductor, and I liked the results. Then I have bought a new inductor ( 1,5 Henry - I guess) and capacitors, the result, after testing some capacitors values in series, is a custom version for les pauls as bellow, see the final schematic:

A six positions selector switch:

The 1,5 Henry inductor (I've used some hot glue to fix it):

Adding the capacitors and a resistor:

Tone cap Update:

The Orange Drop (22nF) tone capacitor mod:

*It provides a more balance and a slightly brighter tone.

Treble bleed update (2026):

The last shot, a treble bleed update on the volume pots (simple, caps-only), because I was obsessed with getting more treble!!

Les paul Pickup upgrade and magnet swap (Seymor Duncan 59 and Pearl Gates)

Les paul Pickup upgrade and magnet swap (Seymor Duncan 59 and Pearl Gates)

Hello friends, Its a humbucker pickups upgrade. I've got tired of my Burstbuckers (not pro) 1 and 2 copy, then I bought a Seymour Duncan Pear Gates Bridge (A2) and a 59 neck (A5), I guessed the 59 sounded a little boomy (lot of basses). The end of the history, I've swaped the pickups magnets: Alnico 5 to Alnico 2.
Now I have a Pearl Gates A5 and a Duncan 59 A2. Showed at the video below:

0:26 neck; 0:45 bridge; 1:05 both pickups
