bulong amp settings — cort CM15R

The December avenue guitar tone for “bulong”, dialed in for a cort CM15R with a Epiphone SG Standard. Studio version, Bulong single (2018) - Tower of Doom Records

Original rig

Not definitively documented; based on the warm, slightly overdriven alternative rock tone typical of Filipino OPM bands of this era, likely a mid-gain amp (Marshall DSL, Vox AC30, or similar) with humbucker guitars. The tone sits in clean-to-edge-of-breakup territory with chorus/delay for atmosphere.

Warm, shimmery clean-to-light-crunch with subtle chorus modulation and spacious delay—emotional ballad tone with clarity and sustain

01Chorus (RECOMMENDED - any basic analog or digital chorus)

RECOMMENDED — not currently owned. A Boss CH-1 or TC Electronic Corona clone would nail the shimmering texture on the verses. Run into amp input.

Rate 3 · Depth 5

02Delay (RECOMMENDED - digital delay with moderate repeats)

RECOMMENDED — not currently owned. A Boss DD-3 or similar at ~350ms quarter-note delay adds the atmospheric depth. Run into amp input (no FX loop on this amp).

Why these settings

The Cort CM15R is a basic 15W solid-state practice amp with only bass and treble controls (no mid or presence knobs). Gain at 3 keeps the tone clean with just a hint of warmth—this ballad needs clarity, not crunch. Treble at 6 compensates for the SG's naturally warm humbuckers while avoiding harshness through the small speaker. Rolling your guitar volume to 8 and tone to 7 softens the attack for that emotional, singing quality.

PRO TIPUse your picking hand position to shape dynamics—pick closer to the neck for the soft verses (warmer, rounder) and migrate toward the bridge for the chorus swells (more articulation and cut). The SG's neck humbucker with tone rolled slightly back is perfect for this weeping, sustained character.
