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

The Vertex Boost is expertly crafted to be a clean boost, buffer and volume pedal in one. The Boost is designed to leave your tone unchanged, while boosting the level of your signal. The Boost also features an ultra-linear buffer to condition your line with ZERO tonal coloration, even with dozens of pedals in your chain. Additionally, you have total volume control by connecting the Boost with any EXP or Volume Pedal and adjusting your volume as you would with a normal volume pedal. When the Boost is OFF, the EXP will function as a volume pedal (sweeping from silent to unity gain). When the Boost is ON, the EXP or Volume Pedal will control the boosted volume (sweeping from silent to wherever the Boost level knob is set). Since your guitar signal is isolated from the impedance of your chosen EXP or Volume Pedal, your tone remains open and full-range, and most importantly, it feels like you're plugged straight into your amp.

Der Dynamic Distortion ist ein klanglicher Hybrid aus den beiden kultigsten Distortion-Pedalen der Rock'n'Roll-Geschichte, dem Germanium Fuzz der 60er Jahre und dem TS Overdrive der 80er Jahre. Dieser legendäre Combo bietet eine unübertroffene Anschlagsdynamik und lässt sich mit dem Lautstärkeregler der Gitarre von glitzerndem Cleansound über Overdrive bis hin zu Fuzz einstellen, während er gleichzeitig den Mittenbereich eines klassischen TS-Pedals und den vollen, weichen Sound eines Vintage-Fuzz bietet.  Der Dynamic Distortion hat alle Vorteile der Kombination der klanglichen DNA dieser historischen Pedale (TS & Fuzz) ohne die Nachteile: Benutze einen Buffer vor oder nach dem Pedal mit NULL Kompromiss im Sound, erhalte klassische Fuzz-Töne, die immer durch den Mix gehen (die meisten Fuzzes gehen im Mix verloren), erhalte den vollen Sweep deines Wah-Pedals mit Dynamic Distortion auf Fuzz eingestellt (unmöglich mit Vintage Fuzz), und erhalte den perfekten Mid-Range Overdrive-Ton mit viel Low-End Fettigkeit und Note Bloom.

The Dynamic Distortion is a sonic hybrid of the two most iconic distortion pedals in Rock 'n Roll history, the Germanium Fuzz of the 60's and the TS Overdrive of the 80's. This legendary combo provides unmatched touch sensitivity and clean-up with your guitar volume knob from sparkley cleans, to overdrive, to fuzz, while providing the mid-range cut of a classic TS pedal and the full-bodied woolliness of a vintage Fuzz.  The Dynamic Distortion has all the advantages of combining the tonal DNA of these historic pedals (TS & Fuzz) with none of the drawbacks: use a buffer before or after the the pedal with ZERO compromise in sound, get classic Fuzz tones that always cuts through the mix (most fuzzes get lost in the mix), get the full sweep of your Wah pedal with Dynamic Distortion set for Fuzz (impossible with vintage fuzz), and get the perfect mid-range Overdrive tone with plenty of low-end fatness and note bloom.
