Der Vertex Effects Steel String Supreme ist ein rein analoger Solid-State-Vorverstärker und ein Overdrive-Pedal, das entwickelt wurde, um das charakteristische cleane, leicht anzerrrende und komprimierte Ansprechverhalten des legendären Dumble Steel String Singer Röhrenverstärkers zu reproduzieren. Basierend auf der Seriennummer #001 eines originalen 100-Watt-Dumble-Verstärkers erweitert das Pedal den Vorgänger Steel String MKII zu einer vollwertigen mehrkanaligen Vorverstärker-Architektur. Die Schaltung umfasst spezielle Regler zur Klanggestaltung, darunter eine aktive EQ-Sektion mit einstellbarem Filter für den Mittenfokus, einen parallelen Clean-Mix, einen Fat-Regler für den unteren Mittenbereich sowie unabhängige Kippschalter für Bright/Deep- und Rock/Jazz-Voicing-Anpassungen. Konzipiert für maximale Vielseitigkeit, kann das Gerät als dynamischer Clean-Boost, Low-Gain-Overdrive oder als Amp-in-a-Box-Lösung direkt vor einem normalen Bühnenverstärker, digitalen Modelern oder Impulsantwort-Cab-Loadern betrieben werden.

The Vertex Effects Steel String Supreme is an all-analog solid-state preamplifier and overdrive pedal designed to replicate the clean, edge-of-breakup, and compressed response of the legendary Dumble Steel String Singer tube amplifier. Based specifically on serial #001 of an original 100-watt Dumble unit, it expands upon its predecessor, the Steel String MKII, by providing a full multi-channel preamplifier architecture. The circuit includes dedicated tone-shaping controls including an active EQ section with adjustable Filter midrange focus, parallel Clean blend, Fat lower-midrange control, and independent toggle switches for Bright/Deep and Rock/Jazz voicing modifications. Engineered for high versatility, the unit can function as a dynamic clean boost, a low-gain overdrive, or an amp-in-a-box solution that can be run directly into standard stage amplifiers, digital modelers, or impulse response cab loaders.

Steel String Supreme

If you use vintage battery-powered pedals, you're familiar with two things: their responsiveness and how quickly the batteries run out. That said, players don't like taking their boards apart to change batteries all the time. With the Vertex Effects Battery Power Supply, it's possible to use your batteries without all of the related hassle. Load the power supply with four 9V batteries, connect to the power inlet, and get rocking! This power supply is intended for use with vintage overdrives, distortions, fuzzes, and wah pedals. But that doesn't mean you can't use select modern pedals. With this power supply on your board, you won't have to tear your pedalboard apart each time a battery dies. Instead, you can spend more time doing what you love — playing through your effects. Read on to see if the Vertex Effects Battery Power Supply is right for you.

Steel String mkII Slight Return Edition

THIS PEDAL WILL TRANSFORM YOUR GUITAR RIG

Don't let the Vertex Boost MKII's name fool you — it's much more than a mere boost. Make no mistake, this multifunction guitar pedal can function as a gain booster, with +16dB of ultra-transparent gain that can either drive your amp into saturation or give your solos a squeaky-clean level bump, depending on where you choose to deploy it. Able to accommodate both line- and instrument-level signals, the Boost MKII also includes ultra-linear input/output buffers that are guaranteed to elevate the sound of your entire rig. This stompbox's buffers can propel a typical mid-level rig into pro-level territory with zero tonal coloration. And if your rig is already 99% of the way there, the Boost MKII will deliver that elusive missing 1%. Beyond that, the Boost MKII's insert jack enables you to adjust your volume via an external treadle-style pedal while keeping your guitar's signal completely isolated — it's like plugging straight into your amp. Boasting a compact enclosure that's 33% slimmer than its predecessor, the Vertex Boost MKII belongs on every tone-obsessed guitarist's pedalboard.

Boost MKII

Ultra-Phonix HRM recreates the much sought after Dumble™ HRM overdrive tone that pushed the tweaked Overdrive Special Amplifier into stardom. Amongst the limited amount of ODS amplifiers produced by the legendary amp maker, a handful were armed with EL-34 power amp tubes rather than the 6L6 tubes found in most ODS amps.  This gives the HRM edition of the Ultraphonix a quintessentially British voicing and EQ shift compared to the original version. The “Master” control determines the total output of the pedal. The “Volume” control adjusts how hard the pedal’s preamp is working, giving you more control over the amount of gain coming from the preamp. Turn up the “Accent” control to increase presence and slowly introduce more saturation into your signal. The “Ratio” control allows you to blend your distorted and clean signal, and the “Tone” knob allows you to accentuate different upper-mid frequencies, ranging from 800-1.6k Hz.
