  • Cheap, clean & clear!

    As reviewed by Chris Maione on 4/28/2010

    I went to get a Crown amp for my drum monitors and they were in the process of changing over models. I tried this amp and am really impressed. Nice, powerful, clean, clear and with a great price. Would buy this product again and recommend it to new buyers on a budget.

  • Very happy!

    As reviewed by Nick R. on 6/7/2010

    I bought this amp yesterday because my current Peavey PV 500 stopped working. I cannot believe how powerful and clear this amp sounds! Im running two MTX TP1200's for speakers and this Amp makes a great combo!
