Vibe Chug

In-your-face rhythm riffs to chug at — vibe drenched, raw, and built to tighten your right hand. Power chords first (funky-metal style), then bluesy funk chords that are rawer than fusion, then the combination. The Drybel Vibe is ON throughout — the trick is chugs stay dry and percussive while the ringing chords swirl.

LEGEND: PM = palm mute · x = muted scratch · / slide up · \ slide down · numbers = frets · counting shown above each riff (1 e & a = 16ths)

01How To Chug It

Rhythm playing improves from three things: subdivision, mute control, and the pocket. These riffs drill all three. The vibe is what makes it yours.

Subdivide out loud

Count "1 e & a" over every riff. Say it while you play. Your right hand should move in constant 16ths even when it's not striking — the gaps are as important as the hits. This is the single biggest rhythm upgrade.

Mute like a drummer

The x scratches are muted strums — the left hand relaxes to deaden the strings, the right hand keeps strumming. This is your hi-hat. A funk riff is 80% mute, 20% note. Control the mute and you own the groove.

Vibe = the movement

Palm-muted chugs are short, so they stay dry and punchy. Any chord you let ring catches the Drybel and swirls. Set the vibe speed to the groove — fast for helicopter pulse, slow for the Trower swell. The contrast between dry chug and wet swirl is the sound.

Practise To A Click

Metronome on, tempo slow enough to nail every mute cleanly (start ~80 bpm). Loop each riff for a full minute without stopping. Record it and listen back for two things: are the chugs even, and do the notes land exactly on the beat or are they rushing? The recording never lies. Speed up only when it's locked.

02Power Chord Chugs — Funky Metal

Two notes each, all downstrokes, all attitude. Root + 5th power chords, palm-muted and syncopated. The vibe swirls the open ringing bits between chugs.

RIFF 1 · E5 · the syncopated entry

The Chug Foundation

E5 = low E–A–D strings · all palm-muted downstrokes · start at 80 bpm

The starting point. E5 chugged in a syncopated 16th pattern — notice the gaps. Your picking hand keeps moving in 16ths the whole time; it just doesn't hit on the rests. Palm mute everything for that tight, percussive chug.

RIFF 2 · E5–G5–A5 · the blues-metal move

Moving Power Chords

E5 (022) · G5 (355) · A5 (577) · the ♭III–IV blues shift as power chords

Now move the shape. E5 to G5 to A5 — that's the root, ♭3, and 4 of E, the bluesiest power-chord move there is (the "Purple Haze" / hard-blues shift). Chug each one, then slam the change. Let the last A5 ring and the vibe grabs it.

RIFF 3 · E5 · 16th funk-metal with scratches

The Muted Machine

E5 with muted scratches (x) — this is the funk-metal groove engine

The funkiest of the three. E5 chugs broken up by muted scratches — the x's are your hi-hat. Keep the right hand in constant 16ths; the left hand lifts just enough to mute on the x's, presses for the notes. This is where funk and metal shake hands.

03Bluesy & Funky Raw Chords

Now real chords — dominant 9ths and the Hendrix 7♯9. Rawer than fusion: these are stab-and-mute funk voicings, played with attitude, not politeness. This is Hendrix rhythm, "Who Knows," raw Wonder-funk territory.

RIFF 4 · E9 · the funk stab

Scratchy 9th Stabs

E9 = x 7 6 7 7 x (A-string root) · stab and mute · the funk rhythm engine

The classic funk 9th shape. Stab it short and staccato, kill it with a mute, stab again. The 9th chord is inherently funky — it's got the tension that makes you move. All in the wrist; keep the strumming hand loose and constant.

RIFF 5 · E7♯9 · the Hendrix chug

The Purple Rhythm

E7♯9 = 0 2 0 1 0 3 (the Hendrix chord) · chugged and scratched

The Hendrix chord as a rhythm engine — it's got the major/minor rub built in (G♯ and G together), so it sounds raw and mean chugged. Strum it percussively with muted scratches between. This is "Who Knows" / "Machine Gun" rhythm attitude.

RIFF 6 · E9 → D9 · the sliding funk

Slide The Nine

E9 (x7676x) slides down to D9 (x5454x) and back · the James Brown / funk slide

Take the 9th shape and slide it. E9 down two frets to D9, back up. The slide is the funk — don't lift, glide. This is the raw funk-rhythm move that works over the whole E vamp: both are dominant 9ths a tone apart, and sliding between them is pure groove.

04In Your Face — The Combination

Everything at once. Power-chord chug, funk stab, and a raw bluesy fill — one loop, maximum attitude. This is the exam for the whole session.

RIFF 7 · E · the full raw statement

Chug, Stab, Snarl

E5 chug → E9 stabs → low-E blues fill (E G G♯ = the safe scale) · 2 bars, loop it

Bar 1: chug the E5 like Riff 1. Bar 2: slam three E9 stabs, then a raw low-string blues fill using the safe-scale notes (E, G, G♯ — the major/minor rub). Loop it. This is funk, metal, and blues in one raw phrase. Play it like you mean it.

05The Vibe-Chug Rig

The Drybel Is The Star

This whole session is a Drybel Vibe Machine showcase. Fast speed = the helicopter pulse under chugs (Riffs 1, 3, 4, 7). Slow speed = the Robin Trower swell over ringing chords (Riffs 2, 5). Ride the speed control as a performance tool — slow it down over a held chord and the swirl stretches. Intensity/depth up for maximum throb.

The Dirt

Broadcast low gain + Butter Machine for the funk chords (raw but clear — you need the chord to speak through the vibe). For the funky-metal power chords, add the SD9 or kick the Broadcast to high-gain mode for more chug weight. Keep it raw — don't over-gain, or the vibe turns to mush. Palm-muted chugs want tight, not saturated.

Guitar & Wet/Dry

The Suhr S with the Landaus for the funk (single-coil cluck cuts through the vibe); the Modern Plus if you want the power chords heavier. Keep the dry Badger dominant for the chug attack — the percussive punch lives in the dry signal. Let the wet Mesa carry the vibe swirl and a touch of the BigSky so ringing chords bloom. The dry/wet contrast is the dry-chug / wet-swirl effect in physical form.
