Pettyjohn Electronics GOLD MKII Full-Range Overdrive/Distortion

Brand New

Description & Specs

From Pettyjohn:

The Pettyjohn GOLD MKII is an update to our best selling golden amp overdrive. The GOLD has been loved for its ability to sound and feel like a high watt plexi syle amp. The GOLD MKII features many updates to the Version 1, including our new 36V dual rail power supply, our new Quiet Bypass system, a new box with recessed bottom screws with many updates under the hood plus an array of carefully selected custom shop upgrade mods to choose from.

We gave the GOLD MKII an extended gain range on both ends of the Gain control. It now effectively goes from a low gain, Plexi style edge of breakup tones to all out JCM 800/900 gain levels on the edge of all out distortion.

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.

We have listened to feedback from players and dealers alike and have come up with a refined GOLD MKII that represents the very best pedal we can engineer.

The GOLD MKII also features two internal mini toggles for further adjustments to the tone: One mini-toggle switches the high cut cap between a clear, punchy Wima cap we love with a classic 716 Orange Drop cap for a smoother, vintage-feeling high-end profile. The second internal mini-toggle switches the headroom of the clipping section.

We're right off the CTA Brown Line 'Paulina' Stop Just North of Belmont and just West of Ashland.

We’re all musicians here at Chicago Music Exchange and we want you to love the gear you get from us. We understand that sometimes you get a piece of gear that doesn’t work out for you. That’s why we offer an easy return policy to take the stress out of purchasing from us.

If you decide you'd like to return an item, please contact your Sales Rep, chat us, or give us a call.

If you placed your order on Amazon or eBay, we advise issuing the return request from your account on the platform of purchase - our Customer Service team will process a refund upon receipt of the item(s).

Most new items may be returned within 30 days of delivery and most vintage & used items may be returned within 3 days of delivery for a full refund, exchange, or store credit. Please pack the product safely for the journey back to us. If the product was shipped for free, the charge will be deducted from refund, unless the reason for the return is outside normal circumstances.

Please contact us as soon as possible if your order was received incorrectly, damaged, or defective. Most times we will give you an RA number (Return Authorization). Why is that number important? This will allow us to speed up the process of the return.

We reserve the right to charge a restocking fee based on the return condition. Some items we just can’t take back for returns, due to a one time function like strings or drums heads and other times it’s not sanitary to do so with microphones or harmonicas. If you aren’t sure if what you bought falls into a category like this, call us (773) 525-7773!

We strive to get your return processed quickly. Most of the time we have it done within two business days. Funds going back to credit cards usually takes two to four business days. CME strives to make sure all customers are happy with their experience. It is our priority to provide great service along with great gear. We always want to be helpful, and open to your feedback. Please let us know your thoughts! If you have any questions, we’re here for you!
