    Pros - Reliable, versatile, lots of power, ampeg sound.
    Cons - Heavy.
    Great amp. Using it with a single 12' Aguilar. Will eventually have two and get 250 watts per cab. Very clear, powerful and warm sound. Like it a lot.

    "Great Portable Head"
    Pros - Weight
    Tone
    Looks
    Controls
    Cons - DI out + Pre-Post EQ button noise issues
    Been using the PF-500 for a number of years now (with the matching 15" cabinet). For the price, this a very decent amplifier in a moderate volume, five piece country band. This amp has always performed next to flawlessly. One niggle is the DI out; at times, I need to toggle the Pre- Post-EQ button to get a signal out to the board. Not sure why this is, but when doing so, ensure that you have the PA gain turned down when doing so - the button generate a signficant "pop" that I suspect led to a subwoofer failure on one PA system I connected to.

    Other than, a fine little amp for middle of the road tone suitable for classic rock, country and blues. Light weight and quite robust construction. I don't baby my amp and it's always done what I asked it to do.

    Pros - Love the flip top lid, which holds your amp. End of gig, just flip it over & you're set. No need for a amp bag, cover, etc. Loved the Portaflex theme.
    Cons - PF series only carries a 2 year warranty. My PF 500 was alittle past 5 years old when the amp went on me. The fan kept cutting out once the instrument cable was connected.
    This was my work horse for the last 5 years. I used this with the PF-115HE cabinet and the sounds were amazing. My main axe is a Nordy VJ4, passive EQ, which this amp made sound like a million bucks. (The Nordy is the best bass I've ever played). No matter what bass, thios amp will make it sound good with all the EQ options.

    My PF 500 was alittle past 5 years old when the amp went on me. The fan kept cutting out once the instrument cable was connected. I contacted Ampeg (LOUD industries) and was told my amp was made in 2010 but I bought it in 2011.

    Ampeg disappointed me in the amp basically went on me after 5 years.

    I purchased a new Ampeg PF 800 as I still love the flip top & the Portaflex series, but if this doesn't last.........I don't think I'll purchase a Ampeg again. I also own the Ampeg Micro -VR amp & 2 cabs (mini me SVT) that I love.

    I've had a pair of PF-500s for going on 4 years now. They've both worked flawlessly. They're revision D, the earliest version which fixed the teething problems the early versions had. I bought one of my amps as a return from MF. I managed to track down the TBer who returned it, who swore the mid control didn't work. It's still working. That amp got loaned out to a friend when his MB800 failed.

    There's a reason these were the best selling bass amps in the world for several years.

    I've been rocking my PF500 and PF115-HE for two years now. I did have to send it in for repair of a cold solder joint about 2 months after I got it (repair done under warranty of course), but it has been trouble free since. I use it for practice and gigs playing with a loud drummer and two electric guitar players. It has enough power to keep up with all of those guys, and if you need to go into the PA you have a DI built in. It's got the Ampeg sound, it's really portable, and fits in the trunk of my car.

    I'm thinking about purchasing this head to match with a GK 4x10. My band has a subwoofer (1x18) i believe, and we run that out of the mixer board. My question is, Should i purchase a 4ohm cab or an 8 ohm cab?

    Thanks in advance.

    6 months into a "new out of the box" PF 500, no problems yet. Great head for the price. Lots of power, easy to dial in and light weight. Goes great with the PF cabinet series.
