If you’re considering adding a treble bleed circuit to your guitar, this post breaks down the options I offer and how they behave in real-world use. I’ve tested these combinations with a range of pickups and pot values, and I’ve narrowed things down to a few configurations that are genuinely worth using.
I don’t offer capacitor-only circuits. Every option includes a resistor, because pairing the two gives a smoother, more usable volume taper, especially with audio taper pots, which most guitars use.
Configurations I Offer
I build two types of treble bleed circuits; both are pre-soldered and ready to install.
Capacitor + Resistor in Parallel
The parallel configuration gives you the smoothest volume sweep of the two — highs are preserved but the taper feels natural across the full range of the knob. It works well with most pickup types and playing styles.
Available combos: 470pF + 220K / 590pF + 150K / 1000pF + 100K
Capacitor + Resistor in Series
The series configuration preserves highs with a slightly softer feel. It tames some brightness at lower volumes which makes it useful for setups where the parallel version feels too sharp or present for a particular pickup and pot combination.
Available combos: 590pF + 150K / 1000pF + 220K
Choosing Based on Pickup Type
Here are some general recommendations based on pickup type. These aren’t rules — just starting points based on how these circuits behave in actual guitars.
Single-Coils — 470pF + 220K parallel. Keeps brightness intact without exaggerating highs. Works well with clean tones and edge of breakup settings.
Jazzmaster & Jaguar (1M pots) — 330pF–470pF + 220K parallel. 1M pots are naturally brighter so smaller cap values keep the tone balanced. Prevents the top end from getting too sharp when rolling back. Some brighter pickups may not need a treble bleed at all.
P90s — 590pF + 150K parallel or series. Preserves clarity while smoothing the taper. Series version can help tame aggressive brightness.
Mini Humbuckers — 1000pF + 100K parallel or 1000pF + 220K series. Maintains articulation without getting brittle. Series version is ideal for warmer vintage voiced setups.
Standard Humbuckers — 590pF + 150K series or 1000pF + 220K series. Keeps tone open at lower volumes without adding harshness. Helps control brightness in darker sounding guitars.
If you’re not sure where to start, the 590pF + 150K parallel is a solid middle-ground option that works well in most setups.
Coming Soon: Install Guide
In the next post, I’ll walk through how to install a treble bleed circuit, whether you’re adding one to an existing guitar or wiring a new build. I’ll include soldering tips, pot compatibility notes, and how to test different values if you’re experimenting.
