I am a long time user of Ampeg products. I had SVT-2PRO, V4BH, 4x10, 2X10, 1X15 speakers.
This head is very effective in giving you a no-frills authentic ampeg sound, in a small package. I use it with the Ampeg 2x10 speaker, closed, no horn, no bass reflex, amazing combo. Typical motown sound.
No distortion of course, but coupled with the right pedals and the right speaker, you'll get an amazing sound that you won't believe.
Of course can't have the same growl of a big tube head, but it weights a fraction and costs a fraction!
Plus, it's amazing for studio recording, as you can get a great tone without the walls shaking!
I advise this head with one (or two) Ampeg 2x10 speakers, and I love the Ampeg scrambler pedal to add warmth and hint of saturation to the sound. You won't fill a big club, but for practice is great and if you play on big stages, you go for DI+ microphone and use stage monitor, then you got a monster sound in a super transportable packaging.
Nothing to dislike for me, amazing product
