On May 1st, 2009, the Mackie, TAPCO, Crate, Blackheart and Ampeg websites will be updated with the addition of warranty URLs (e.g. www.mackie.com/warranty) expressing new A Stock warranty terms. These warranty URLs will go live on May 1st, 2009. Formerly, warranty periods for these LOUD brands appeared in a variety of locations – in product manuals (for Mackie and TAPCO) and on warranty cards and hang tags (for Crate, Blackheart and Ampeg). In order to streamline and clarify this process, Mackie, TAPCO, Crate, Blackheart and Ampeg warranty periods and terms will be communicated in full on the warranty pages.

Meanwhile, the products that bear with them the new warranty periods (as reflected in the box contents of each product) are being tracked by serial #, and contain new warranty content referring customers to the appropriate brand website. The information below reflects the product warranty periods that will be effective on May 1st, 2009 for the Mackie, TAPCO, Crate, Blackheart and Ampeg brands: Mackie: A 3-year, nontransferable, inclusive warranty on electronics and a 2-year, nontransferable, inclusive warranty on drivers (where applicable) apply to loudspeakers (active and passive), power amps, powered mixers, and HR studio monitors.

  • Ampeg Power And Quality Is A Must For Any Serious Bassist

    As reviewed by Eric Marshall on 5/28/2012

    I picked up this little jewel new from Guitar Center in Greenville, SC and have been really pleased with my purchase so far. The guys at GC have been really helpful to me and some of them even remember my name when I walk through the door and that really makes me comfortable when I'm doing my shopping. I'm currently running this amp through (2) Hartke VX1508 series cabinets and it literally makes my entire house thump. I really dig the cosmetics of this amp especially with the blue LED light that signifies being online. It's unfortunate that someone else bought this model amp that was defective because mine has given me zero issues whatsoever and I would recommend to you and your mother.

  • Awesome Amp and Power

    As reviewed by Luis Martinez Jr. on 11/30/2011

    I have owned this amp for about 3 months and all I can say is darn what power! It's very compact and light for 500 watts and weighs about 11 pounds. This amp was inspired by the iconic Ampeg B-15 of yesteryear. It has awesome tone which can be changed by a 5 postion frequency knob. It can also be changed by the standard bass,midrange and treble knobs. It has an ultra hi button which gives those tight crisp clean sounds and an ultra lo button which gives those deep,deep bottom ends especially when using a 5-string bass like I do. I have this amp paired with the Ampeg 610HLF which is a 600 watt rms cab and a 500 watt head so plenty of headroom. I would highly recommend this amp to anyone who is looking for that classic ampeg tone of the 60's or 70's as well as an excellent tone sounding amp for any music genre.

  • Perfect for me

    As reviewed by mike suddertj on 6/1/2013

    With all the knobs set flat it has a pleasant tone; turn up the gain and it punches pretty hard. At first it seemed weak for 500 watts, but unlike many amps the volume and tones increase smoothly as you crank the knobs rather than peaking early only to turn to mush when you turn them past 7. On my regular job they put us outside since it turned warm, and this amp is giving me the best sound I've had in years! Also, Guitar Center has been very helpful and patient.
