Fender Pro Junior IV

I was after a simple design to achieve vintage rock tones and this thing gets me there. I experience it being very responsive to dynamic playing. It has huge volume so don’t be fooled by its size. For reference, of the 12 levels of volume, I play mine at 4.5 and it easily stay on top of the band mix. It responds well to the volume pot on guitar. It works well with overdrive and boost pedals. I’ve used mine with humbuckers and single coils and can find great tones with both. I don’t experience the sound being boxy but I keep it off the ground when playing. It warms up quick and can be played within a few seconds. The finish and build quality is as expected. I did take a screwdriver after around 25hrs of use to lightly tighten the cabinet screws. One of the handle bracket screws was not tightened flush against the handle bracket but everything else is well assembled.
I highly recommend this amp. It’s my first tube amp but can see myself being happy with it for many years.
