Voicing
The Marla S20V is my take on all the best Tweed Era sounds compacted into one gig-worthy combo. Think 5E3 DNA with modern refinements.
At first glance, it looks much like the old Tweed Deluxe. But that's where the similarity ends. Unlike a typical tweed deluxe, the S20V gives you more clean headroom and drastically less compression at low volumes. That means sparkling cleans that stay clean until you decide to push it, and a pedal platform that plays nice with everything on your board. If you're looking for a Fender alternative with real boutique quality, this is it.
Two independently-voiced channels, each with high and low sensitivity inputs, give you a wide variety of jumping-off points for your signature sound. The channels run separate signal paths, so jump them with an ABY or jumper cable to blend both worlds. Jumping the channels creates a sensational amount of midrange overdrive and top-end sizzling distortion—the kind of harmonic complexity that made those old Fender circuits legendary.
And at under 36 lbs, the S20V is one of the lightest 20-watt tube combos on the market. Your back will thank you.
Channel One — Bright & Bassy
A loose, open feel that reminds me of a 5D5 Pro Amp mixed with a '59 5F6-A bright channel. Extended low-pass cutoff like a Bassman, but paired with a 12" Mojotone Anthem speaker that brings enhanced low end—much like the old Pro Amps delivered. A modest bright cap adds just enough crispness for cut and clarity. This is your channel for single coils and rhythm work. Perfect for blues, country, and classic rock tones.
Channel Two — Tight & Narrow
Voiced like a Princeton, but with a wider-than-average tone sweep that can cut well beyond typical high-end frequencies. More control over your sound when you need it. Great for sparkly cleans, humbuckers, and sculpting lead tones.
Tube Layout
Ships with JJ 12AX7s for pre-amp and phase inverter, JJ 6V6GTs in the power section (fixed bias—plug and play), and a JJ GZ34 rectifier for high plate voltages and low sag.
Want a tamer sound with less top-end hair on the overdrive? Swap in a 5U4GB rectifier to drop the voltages for a more modern, compressed character without losing notable power.
The Cabinet
20" x 20" x 9" solid pine with a 5/8" semi-open back baffle. The oversized cab produces robust low end, the solid pine keeps top end pronounced, and the semi-open back makes notes feel more resonant than anticipated.
Hand-stained with polyurethane finish to handle the elements.
Studio tip: Mic the speaker from the front AND the back. It's an old '70s trick—the mix of cab and speaker cone sounds like a freight train.
