BITMO VOXMO4 MOD KIT FOR VOX AC4TV AMP - HEAD OR COMBO

Amp is not included

A new preamp tube is included (NOS JAN Philips 12AT7WC while supplies last).

Works with both the head and combo versions of the amp.

I love Vox amps. I have been playing them for 40 years (ouch!)  The AC4TV is a great amp and definitely sounds like a Vox.

The BitMo VoxMo4 mods do not try to make the amp into something else, just a bitmo better Vox. The kit includes a 12AT7 preamp tube. With this amp, I think it makes a huge difference, extends the range of the controls and smoothes everything out. The kit also adds a switch with 3 different voicings, making the amp much more versatile. The middle position is the (upgraded) stock configuration. The low position shifts toward a smooth treble, tightens the bass, increases the headroom and provides that “Vox jangle” perfect with your Rickenbacker 12 string for Byrds and Beatles. The   3^rd position shifts the mid frequencies down and raises the gain a bit for a stout clean or overdrive that can go from crunch to chocolaty brown cello sound to a tight, biting boost – think Stones and Beatles. All 3 voicings are very touch sensitive and great across the full range of the volume control, going from warm or sparkly clean to balzout overdrive with lots of interesting shades in between, all with that magical Vox midrange.

Assumptions, warnings, etc:

·            While these modifications are very easy to do but you will void your warrantee.

·            Tools needed: screwdriver, knife, soldering iron, rosin core solder, wire stripper, needle nose pliers, drill and bits.

·            I consider these mods to be of moderate complexity - not recommended for complete novices.

·            Skills needed: be able to solder and drill a hole in the metal chassis. For advise on soldering techniques, check the web—for example:
