Treble bleed, Eldred mod, Arlo mod

Below are a few reference values and diagrams for treble-bleed kits (volume kits), Eldred mod, and Arlo mod.

Treble-bleed mod, Treble Bypass, and Volume kits refer to the same thing. There are a few variations. Easy to make, cheap to buy pre-made.

Treble bleed values

1000-1500 pF capacitor: Lower values = higher frequencies, higher values = lower frequencies

100-330k-ohm resistor: lower impedances are brighter, higher impedances are darker

I do it this way

Arlo mod

Resistor 3k (3.3k ohm).

Cap 0.01uF

Cap 0.005uF

Eldred mod

A wiring diagram using the Eldred mod is here

Cap 4700 pF (0.0047 μF)

<4700 pF will result in more highs because less treble is bled to ground and vice versa.

A good range to tinker with is 1000 pF up to 6800 pF (0.001 - 0.0068)
