Ampeg Portaflex PF-800 Bass Amplifier Head (800 Watts)

Compact yet powerful, the Ampeg PF-800 gives your bass 800 watts of Portaflex tone and a powerful on-board compressor, all while weighing only 11.8 pounds.

The Ampeg Portaflex PF800 bass head brings you 800 watts of low-end power, in an exceptionally compact and lightweight unit. It employs Ampeg's extensively developed and much lauded MOSFET solid state preamp. This gives you an amp with a super-clear clean tone, packing plenty of punch and power.

Input and Outputs

Your Portaflex PF800 is a single-input design with a Mute and a -15 dB pad switch right next to the 1/4-inch input jack. The amp boasts both a single 1/4-inch and a SpeakON-style output for running to the cabinet of your choice. It pairs stylishly with the many fine bass cabinets in the Ampeg line (like the PF-115HLF or PF-210HLF), but will serve any suitably-sized cabinet with an minimum impedance of 4 ohms.

Lots of Ways to Play With Your Tone

You'll find a wide range of tonal control on the Portaflex PF800. To start, you've got classic Bass and Treble knobs to make sure the lows and highs of your tone are where you want them. Then you can really start getting into the intricacies of tone using the 5-position midrange control to craft the real "voice" of your bass sound. An Ultra Lo switch is there when you want to add more thud to the mix. The Ultra Hi switch is perfect when you need to drop a bass solo that will cut through the rest of the mix. You can also use the integrated Compressor to achieve still tighter and cleaner tones when you're raging at high volumes.

Awesome Features Throughout

A number of useful features make the Ampeg Portaflex PF800 a read more great amp for gigging musicians. There is an FX Loop Send and Return. You'll also find a Power Amp input and a Pre-Amp Output. The balanced XLR Direct Out on the rear panel runs easily to live mixers or recording consoles with a switchable -40 dB pad, and even features a pre-/post-FX loop switch! A thoughtfully included Tuner Out allows you to tune silently and quickly via a direct bass-to-amp 1/4-inch line. Finally, you've got a Ground Lift switch to eliminate ground noise when it arises.

Even More Control with an Optional Footswitch

The Portaflex PF800 also has a 1/4-inch TRS footswitch input that allows you to connect an Ampeg AFP2 (not included) or any other dual TRS footswitch to control the Mute and FX On/Off control.

before this I had a PF350 and found a decent sound for a 2x10 speaker cabinet. moved to the states and needed that Ampeg Fridge. I dint wanted to have a 80lbs tube amp to match it and jump to my mind the PF I called Ampeg asking if this set up will match up and it was fine! When the amp arrived (pretty quick) I dialed a good sound a huge headroom from a 12lbs amp and still have ampeg classic tone all over!
