The Vox AC4TVH – A Modern Classic

The Vox AC4TVH and matching V112TV speaker cab form a mini stack with vintage style and that classic British sound. Vox Amplification released the AC4TV tube combo amp and the AC4TVH head, along with the matching V112TV speaker cabinet in 2009. The combo version of the AC4TV was a huge hit and continues to be a big seller. But the head version (which shares the exact same tube chassis as the combo) didn’t sell as well and was discontinued in 2013 or 14. Therefore, they are pretty rarely seen in the wild.

AC4TVH Head

The AC4TVH is a 4 watt tube amp (actually more like 5 watts) with a built-in attenuator that allows you to dial in power at 1/4 watt, 1 watt, or 4 watts output. Perfect for practicing at home, playing small venues, or a recording studio. The 12AX7 preamp tube and EL84 output tube creates that classic Vox tone.

V112TV Cabinet

The Vox V112TV speaker cabinet is fitted with a custom-made Celestion 12″ speaker. Its sound is unmistakably Vox, delivering that distinctively British top-end tone. The guitar speaker cab was designed to complement the AC4TVH head.

The BitMo Mod

I installed the BitMo Mod myself. The mod adds resistors and tone caps to the preamp circuit while adding a Tone Switch to the top panel. The 3-way Tone Switch expands your tonal range from 1) clean and jangly, to 2) classic VOX, to 3) saturated tube overdrive.

This amp is serial number 000007, meaning it’s the seventh AC4TVH to roll out of the Vox factory back in 2009. See the pix.
