Frequently Asked Questions

Have questions? We have answers! Take a look below and see if we’ve addressed what’s on your mind.

Does it matter which end of the cable I plug into the guitar?

Yes, it DOES matter. PowerWire is directional and the larger connector must be plugged into the guitar. Signal passes from the larger connector’s amplifier downstream to your other gear.

What makes PowerWire different than other instrument cables?

PowerWire’s patented circuitry overcomes the sound-deadening and parasitic capacitance and inductance inherent in all passive cables. Even at lengths up to 100 feet, PowerWire delivers a clean amplified signal from the guitar to the pedal board or amplifier. No other cable can claim this level of signal retention regardless of the cable length.

Why is an amplified ‘active’ cable better than the passive cable I already use?

Only an ‘active’ cable can overcome the inherent sound degradation that occurs in an instrument cable. PowerWire’s built-in pre-amp makes passive ordinary cables sound dull in comparison and reveals how much signal is lost through even high-end instrument cables. Everything about a passive cable inhibits sound the second it receives the signal and ‘degrades it foot by foot’ as it passes it along its length to the next piece of equipment. PowerWire’s pre-amplification overcomes the cable capacitance that plagues other cables. No matter what instruments you play… electric, acoustic, bass, slide, steel, uke, fiddle, mandolin… anything with a pickup, sounds better with a PowerWire..

PowerWire doesn’t look much different than other cables. Where is the amplifier located?

The amplifier circuitry and batteries are located in the larger of the two cable connectors. It’s surprising how much power is packed in such a small, inconspicuous space. The amplifier is well protected and insulated in its metal housing, but treat it with care. Be sure to read the “Cable Care’ (link to Cable Care) for best practices related to PowerWire.

Is external power required to operate the PowerWire amplifier?

There are no external power supplies required, nothing but the cable itself. Everything is contained in the cable connector, including two long-lasting easily-changed batteries. No one is likely to even notice you are using a PowerWire. The only thing you’ll see is that the guitar-end connector is slightly larger than the other. Just plug it in and play. The audience may not see it but they will hear it!

There are 4 different PowerWire cables. How are they different?

Each PowerWire cable is unique and well-suited to specific applications. Clean boost cables come in two gain levels (CB6 and CB0) delivering 6 and 0 dB gain for electric and acoustic guitar pickups. CB0 is best matched with high-output pickups, acoustic electrics and steel guitars. CB6 is a highly effective universal cable for vintage, standard and single-coil pickup electric guitars. PowerWire SS offers bass guitars a richer, fuller spectrum of sound described as ‘punched-out’ with a subtle sub-harmonic in the lower frequencies. PowerWire TS09 adds a classic distortion effect that some have called a ‘tube screamer in a cable’. PowerWire SS and TS09 can tune their respective effects using the volume control of the guitar.

How do I submit registration for my PowerWire?

Registration is the best way to ensure warranty and service for your cable, and is easily completed online. Click Here to register your product.

What is the warranty period for PowerWire?

PowerWire cables come with a 6-month warranty from date of purchase. Registration is required.

How often do I need to change batteries, and how do I do it?

Batteries will generally last up to a year, but the initial set that was shipped with your cable may need changed sooner depending on the time between production of the cable and when it was purchased. If you notice a change in sound from your cable it is likely to be an indication that the batteries need to be replaced. Changing batteries is simple. The cable requires button-cell batteries (either #675 or #357) available at many drug and discount department stores.

What else besides the need for new batteries may cause a change in the sound of my cable?

Sound quality may diminish, change or stop entirely if damage to the cable, connectors or amplifier has occurred. Conduct a thorough visual and tactile inspection of the cable and connectors to identify evidence of cable breaks, kinks, cuts or loose wires within the connectors. Do not attempt to repair the cable. If damage is suspected, contact R&M Service at support@rmtonetech.com

What do I do if my PowerWire needs service?

Service is available by contacting support@rmtonetech.com. Provide your phone number and a service representative will call you. A return merchandise authorization (RMA) will be provided prior to returning the cable for service.
