The Pettyjohn GOLD MKII is an update to our best selling golden plexi overdrive pedal, reknown for its MIAB (Marshall in a box) sound and feel.
Now with greatly extended controls and gain range the GOLD MKII can satisfy almost anyone looking for anything from an always-on low-gain sweetener to fully overdriven, thick rhythm playing chords to soaring, classic leads.
Featuring many updates from the version one including Pettyjohn's new proprietary 36-volt dual rail power supply, a new quiet bypass system, a new box with recessed bottom screws along with many updates under the hood refinements and an array of carefully selected custom shop upgrade mods to choose from.
The GOLD MKII is designed to be a full range pedal, which means all tones pass 20Hz to 20kHz. We did this to let the user have the most ability to shape the tone to fit their needs.
To compensate for this extra frequency range, the GOLD MKII is loaded with our most powerful 3-band EQ featuring our wide-range, sweepable low cut and high cut filters and a powerful sweepable mid bell. With an ultra wide gain range and extremely flexible EQ section, there is no amp the GOLD MKII can’t transform into a formidable rock machine.
FOUNDRY Series - Dual Rail Power SupplyAll Pettyjohn FOUNDRY Series now include one of our biggest innovations ever: a new proprietary dual rail charge pump. This little gem is a major upgrade from our CORE Series charge pump and is a sophisticated dual rail dc to dc converting internal power supply. Our charge pump provides an incredible +/-18v of internal power, for a total of 36v, and all from a standard regulated 9v power adapter (200mA). Say what!?
When you increase voltage you increase the headroom which then affects the tone and feel of a pedal. Dual rail power supplies are usually found only in classic studio gear, until now. The FOUNDRY Series charge pump delivers up to a massive four times the headroom of most guitar pedals. This high headroom imparts an openness and 3D quality that is unique to Pettyjohn FOUNDRY Series pedals. 36v is the maximum spec for most opamps empowering the high-qualify opamps in FOUNDRY Series pedals to operate at their maximum potential.
FOUNDRY Series - Silent BypassWe have had many requests for this over the year and were happy to announce all FOUNDRY Series now shop with a totally quite foot switch enhanced with a sonically transparent gold contact relay. It auto-bypasses when the power is disconnected, never leaving you in the dark. Hardwire, classic true bypass is available via custom order on our website for those who may prefer this option.
FOUNDRY Series - The Indestructible Enclosure
While most pedal companies opt for an off-the-shelf enclosure, we took the path less traveled. FOUNDRY Series boasts a nearly indestructible two-plate custom enclosure design forged from mild steel right here in the USA. The boxes feature a gentle sloped front edge to protect the top control panel, features recessed bottom screws, and is finished with a thick powder blast of sparkling hues that will have you gitty as a goon.
FOUNDRY Series - Studio Grade Components
At Pettyjohn we build true studio-grade pedals. No, this isn't some cheeky marketing jargon; we accomplish extremely low signal noise with carefully selected top-shelf components:
Burr Brown OPA input and output buffer
Audiophile grade, through-hole 1% metal film resistors
Top-shelf WIMA and Silver Mica caps used in tone sensitive operations
Lead-Free PCB constructed with Audiophile lead-free silver solder
Carefully selected upgrade mods for every Pettyjohn pedal
Dual 990 Discrete Opamp Mod - Our standard GOLD MKII ships with high quality Burr Browns opamps taking care of input and output buffering. Upgrading to the GOLD MKII opamps replaces one Burr Brown with a dual studio-grade 990-style discrete opamp. This chip runs the input buffer and the active level control stage giving the GOLD a more natural, open sound quality that is truly uncompromising.
Klon Mod - We have secured a small stash of rare NOS (new old stock) blue stripe germanium diodes from Russia, the same ones often found in the original Klon Centaur pedals. Installed in the low headroom setting with the Klon mod and the Gold's standard Plexi tone magically transforms into a Klon. We noticed a tightened lowend, warmer highs and a smooth mid forward drive quite reminiscent of those classic big box overdrive pedals, thus it is the Klon Mod.
