  • Beringer 450fx

    As reviewed by imsnowyone on 4/27/2007

    I am using this amp for keyboard & voice mixing. It does the job well. I have a Yahama PSRGX 76 keyboard and it works great. I do not use the special effects built into the amp because, I have them on the keyboard. The 5 band equalizer gives exelent sound shaping and makes the vocals sound great. I think this would also make a great guitar amp because of the special effects that are built into the amp.

  • Does what i asked it to do...

    As reviewed by Jacob S. on 2/6/2010

    I have had this amp for about a year now, and I use it as a practice amp in my bedroom for my keyboards, guitar, bass, drum machine, and mics all at the same time(i had to get a mixer when i ran out of inputs). It is loud enough to play a small house party on its own. Its nice to have multiple inputs to plug in multiple instruments, but if you put in more then 2 your sound will get somewhat distorted(that's another reason why i plug in everything into a mixer before it goes into the amp). I highly recommend this for anybody on a tight budget.

  • Nice amp for the price

    As reviewed by Bob B on 11/28/2009

    I picked up this K450FX at GC last year and it has been consistently good. Used at home through my M Audio Fast Track Pro and AKG Perception mic, along with my Yamaha keyboard, I'm totally satisfied with the tone and sound. For gigs, I will get something more powerful, but for my present needs this keyboard amp performs well for the money. No problems at all! I like the EQ too, nice touch. Effects are mild, but I record clean anyway, so for me it's perfect. Worth checking it out if this is your price range.
