Gold Coverage Protection
Protect your gear
Gold Coverage Protection
Gold Coverage goes above and beyond the manufacturer's warranty to protect your gear from unexpected breakdowns, accidental damage from handling and failures. This plan covers your product for one, two, three or up to five years from your date of purchase, costs just pennies per day and gives you a complete "no-worry" solution for protecting your investment.
Gold Coverage Includes:
- Unexpected and unintentional spills, drops and cracks
- Normal wear and tear
- Power surges
- Dust, internal heat and humidity
Other plan features include:
- For products over $200, No Lemon Policy applies. If it fails for the same defect 3 times, it is replaced on the 4th breakdown. (Does not apply to failures due to drops, spills, and cracks)
- For products under $200 experiencing the above failures, a Musician's Friend gift card will be issued for the full price of the product + tax.
- Shipping fees covered if required for repair or replacement
- Plans are transferable in the event merchandise is sold
- Plans are renewable on new gear
*Limitations and exclusions apply. See terms and conditions (Opens in new window) for program details
Term for New Gear begins on date of purchase but does not replace the store return policy or manufacturer coverage.
Overview
Duophonic hybrid-analog synthesizer with dual filter, 200 patch memory and full USB-C MIDI control.
The PWM Instruments Mantis Duophonic hybrid-analog synthesizer is a collaboration between the late Chris Huggett (Gnat, WASP, OSCar) and PWM. In development over the last period of his life, Huggett threw everything he could into the Mantis. Although incomplete when he passed away, he handed his part of the project over to Paul Whittington to see what could be made of it.
Oscillators
The OSCs are generated at boot up using complex mathematics. They run on a DSP chip that gives ultimate stability and control without compromising the unique sound. This is what makes the synth a hybrid; however, everything after that through the mixer, gain staging and the filter is analog.
VCF
The Filter is a multi-mode state variable VCA Filter with overdrive. It’s built using the SSI2164 chip in special configuration designed by Chris Huggett. There are two filters—one for each analog signal path. They can be combined in series or parallel and used with the width control and width modulation to create that distinctive sound only heard on the OSCar.
FX
The Mantis has two simple digital effects: Reverb and Chorus. Reverb has a time and level adjustment but also a high- and low-pass filter that can be switched in to limit unwanted lower mud and/or higher bouncy twinkles.
Envelopes
The Mantis has two ADSR envelopes but each has an additional Sustain Fall parameter and negative and positive velocity modulation level hardwired for convenience. Sustain Fall allows you to create a drop before release even while a key is held for greater sound design possibilities. Each envelope can also be put into repeat mode to act as a pseudo LFO if you wish.
VCA
The gain staging on Mantis is all-analog and is run through the SSI2164 VCAs. The signal is twice amplified to ensure the overdriven sound is warm and clips naturally.
The Mantis includes a power supply (9V 600mA), USB-C lead and getting started guide.
