The PF-20T reproduces the legendary B-15 design concept—all-valve, with record-ready sound—but in a more modern, durable package.
Top-shelf Audio Engineers know that when it comes to getting great tone, few things do a better job than a low-powered all-valve head. If you’re ready to get serious about your studio or small gig sonics, put the PF-20T on your short list.
The legendary tone and portability of the all-tube Ampeg Portaflex amplifiers is faithfully reproduced in the PF-20T. This all-valve Portaflex head provides a harmonically rich and studio-worthy 20 watts RMS of pure Ampeg tone to satisfy the most discerning bass player.
Ampeg have included a simple user-adjustable bias adjustment for easy valve replacement along with pre-amp and transformer balanced direct outs for maximum versatility. No speaker load is required for silent recording – you can even use the PF-20T as the ultimate dedicated valve DI.
All-tube Ampeg tone
Inside of the PF-20T Portaflex bass head, you’ll find a set of glowing 6V6 and 12AX7 valves. The valve design of this amplifier allows you to get that warm, harmonically rich tone Ampeg is known for, or push it hard to get an overdriven tube growl. So whether your ideal Ampeg tone is bringing Motown thump, or grabbing a pick and punching the front end of your amplifier as hard as you can, you’ll fall in love with the tones in the Ampeg PF-20T Portaflex.
Huge sound – compact size
Even with the diminutive size of the PF-20T Portaflex amp, you have all you need for getting huge tones through your cabinet, on your tracks, or both at the same time. The straightforward front panel makes dialing in your tones a snap, while the back panel offers XLR outputs for preamp out (with pre/post EQ switch) and transformer-balanced line-out. Its smaller footprint is easy to transport, and it sits beautifully on a recording desk or affixes to current Ampeg Flip-top cabinets. And the whole tube package is less than 16 lbs.
A great recording tool
One of the most useful features of the PF-20T Portaflex bass amp is its ability to run without a speaker load. Combing this with the preamp out (with pre/post EQ switch) and transformer-balanced line-out, you can optimize the PF-20T as a desktop unit for running direct and sending your valve tone straight to your recording rig. The smaller size allows it to sit right on your studio desk within easy reach, and the black metal casing and glowing valves look super cool and classy.
