Description
Every bassist who’s played through a classic Ampeg rig knows that thick, warm push that only tubes deliver — the PF-50T bottles that exact character into a Portaflex head small enough to toss in the back seat. It’s not a scaled-down imitation; it’s the real all-tube signal path Ampeg built its reputation on, just tuned to a stage-friendly 50 watts.
Under the hood you get a genuine tube preamp and power section (2x 12AX7, 1x 12AU7, 2x 6L6) driving your tone through Bass, Mid, and Treble controls plus a 5-position mid-tone switch for dialing in everything from vintage thump to modern growl. Ultra Hi and Ultra Lo boosts let you push the extremes when a song calls for it, and the 0dB/-15dB inputs give you room whether you’re running passive or hot active pickups.
This head doesn’t demand a speaker load to run safely, so you’re free to use it for silent practice or DI recording without worrying about damage. A transformer-balanced line out with pre/post EQ selection and ground lift makes it just as home in a studio session as on a stage, and the user-adjustable bias control means it can keep sounding right as tubes age.
Pair it with a PF-112HLF cabinet for a rig that’s genuinely gig-ready — light enough to load in solo, warm enough to fill a room. At 7.3 x 13.9 x 10.4 inches, it tucks into tight backline spaces without sacrificing an ounce of that unmistakable Ampeg voice.
