Description & Specs

Please Note: The front top corner has some scuffs and scratches on it. No original packaging.
The HMW (Heavy Metal Warfare) is the ultimate single channel amp for achieving all ranges of rock and metal tones from barely distorted to extreme modern heavy metal in one amp. With high and low gain inputs as well as a high and low gain switch altogether there are 4 input sensitivities to choose from depending on how aggressive of a sound the user is going for. The versatility of this arrangement allows the HMW to function as either a straight plug and play ripping heavy metal amp or a pedal platform style amp where moderate distortion sounds are dialed in then modified with fuzzes, boosts, overdrives, etc.

EQ is expansive but not excessive. Settings are divided into preamp and power amp controls with Gain, Treble, Middle, and Bass setting the tone of the preamp and Volume, Presence and Depth used to adjust the overall volume and frequency response of the power amp. Two EQ shift switches were added which can further shape the response of the high and low frequencies to help tailor the sound to different playing styles whether it's fast technical metal or slow pulverizing sludge. Both switches off (down) is the stock sound of the amp. Treble shift engaged increases brightness and presence and also helps accentuate pick attack. Turning the bass shift on makes the overall sound thicker and the response more slow and woofy.

Due to space constraints this amp does not have a line out like the normal size version. Other than that it is the exact same amp as the HMW except in a smaller enclosure.

The back panel has two parallel speaker outs and a 3-way selector switch for 4, 8 or 16 ohm operation. FX loop is optional on this model.

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!
