Product Description

Ampeg's Portaflex PF500 bass head delivers a staggering 500 watts of power in a super-compact design providing pure Ampeg tone in an extremely portable package. The PF500 harnesses the performance of Ampeg's highly-researched MOSFET preamp, setting a standard for solid-state tone.

Tonal control on the Ampeg Portaflex PF500 is no problem with the 5-position midrange control and classic hi/lo boosts while features like the direct out with ground lift and pad are perfect for the gigging bassist. There's even onboard compression for a tighter, cleaner tone at high volumes. Pair it with the PF-115HLF or PF-210HLF flip-top cabinets for the vintage styling and portability of Ampeg's iconic Portaflex originals. zZounds is an authorized dealer of Ampeg products.

Customer Reviews
4.5 out of 5 (27 ratings) Rate and Review This Product
zZounds has verified that this customer bought this product from us. "Awesome little amp!"
Sound: I purchased this amp as a back up when my SVT CL was being repaired. Honestly, this is an awesome little amp! The tones are great and it’s loud! I use a Fender American Standard Jazz 5 string with an Ampeg Heritage Series SVT-410HLF. I tried the SVT 7 Pro and I prefer the tone of the Ampeg PF-500 Portaflex. Absolutely recommended! Feature: Compression and Ampeg tone! Ease of Use: Good layout - simple! Quality: Well built! Value: For $400 - WTF! Manufacturer Support: On the 2 occasions I have called them, they were very helpful The Wow Factor: Looks retro - I like it! Overall: I may buy another one as these will sell fast

zZounds has verified that this customer bought this product from us. "Ampeg hit this one outta the park!"
Sound: Just got mine today and it has the pure Ampeg tone! I dialed in the compression at about 10 o'clock and it evened it out nicely and I really didn't hear a tone change at all. I boosted the gain until it started to break up, then backed off a hair and found that sweet spot. I also found that I didn't need to crank the bass knob at all - it has plenty of low end with the bass knob at 12 o'clock. I was using my stage rig (Avatar 2x10 NEO) but set up in the living room so things might be different on stage, but I doubt I will be disappointed. Feature: The 5 way mid frequency switch makes it super flexible, and all of the other controls typically found on the SVTs (bass boost, high boost, etc) are very nice and useful. Ampeg doesn't waste time on fancy features that do nothing - this amp has stuff you can use. Ease of Use: Piece of cake. It's truly plug and play. Quality: Seems to be very solid and well made. Value: I paid $399. Unreal, it sounds like a $1000 amp. Manufacturer Support: NA so far The Wow Factor: Gotta have one if you like light weight and Ampeg tone. Overall: I was using my stage rig (Avatar 2x10 NEO) but set up in the living room so things might be different on stage, but I doubt I will be dissapointed. I should report back after a gig or two but I doubt I will change anything.
Style of Music: pick one - i play and enjoy most everything

1. We offer the most flexible payment plans in the biz

zZounds offers a number of different installment payment plans that make it affordable and convenient for you to get the gear you really want today, without racking up risky credit card debt.

Other stores offer house credit cards that require you to fill out an application and pass a credit check--and, if you qualify, leave you vulnerable to exorbitant interest charges once the initial promotional period ends. zZounds payment plans are easy to get and simple to use; plus we'll never charge you interest!

2. We guarantee the lowest price

If we don't already have the lowest price, just send us a link to any legitimate competitor's offer, and we'll beat their price as long as we're not losing money on the deal.

To submit a request for a lower price, click "Seen it for less?" on any product page. We answer most lowest price requests within two hours. For extra peace of mind, you also have 30 days after your purchase to find a lower price; if you do, we'll refund the difference.

5. Our customer service is consistently rated the best

zZounds customer service is consistently rated at or near the top on every major comparison shopping website--probably because we only hire experienced musicians with outstanding customer service skills to work in our call center, and they don't work on commission. To us, this is our most meaningful measure of success. zZounds has served over a million customers since 1996, and they're the only critics whose reviews really matter to us.
