T&T x Vox AC15C1 - Alnico Blue

$1,150.00

This is our take on one of the top selling amps in the world, the Vox AC15.

The AC15 is a great amp straight out of the box, it’s well designed and built with quality components, & with this one we’ve upgraded the speaker to a Vox/Celestion Alnico Blue.

To improve on this strong start, we took inspiration from Lyall Cadwell (‘Psionic‘ audio channel on YouTube) and implemented some of his ‘Psionic’ mods. These included; changing the power filtering to the vintage AC style to improve playing dynamics, adding the ability to switch between the vintage & modern tonestack via a push-pull ‘Top-Boost’ volume control, & rebalancing the ‘Normal’ output to match the ‘Top Boost’ channel.

One major feature we felt is missing from the AC15, is being able to easily jumper the ‘Normal’ & the ‘Top Boost’ channels together, so we’ve added channel jumping via a push-pull volume control on the ‘Normal’ channel *.

As part of the usual T&T rebuild/refurbish, we upgraded the power filtering capacitors to top-quality Nichicon, preamp/signal film caps with Panasonic, & our favourite Nichicon ‘Muse’ bi-polars for the cathode bypass caps. Signal & power resistors were also upgraded to 1 watt or greater Vishay metal film.

To minimise the noise floor, wiring has been dresssed & re-routed where needed, shielding added to the back of the cabinet & the wiring from the input to V1 covered with a grounded mesh.

Finally we added a little bit of bling with some custom made gold vents to replace stock plastic/black ones & updated the handle & protecter screws to match.

Other included accessories are a cover and dual footswitch controling the Reverb and Tremolo.
