Vox AC4 with Mercury Magnetics Upgrade kit

VOX AC4 modified with the Mercury Magnetics upgrade kit. Increases the headroom, smooths out the tone and makes this amp a pedal friendly little beauty. The kits adds not only new transformers but a choke to the circuit that lowers the noise and tightens the bottom end, even through the stock 10" Celestion speaker. This kit is a challenge but is well worth the upgrade. It takes this little practice amp and makes it recording worthy.

Hi Bitterclinger, I haven't had the chance to work on a Bogner Alchemist. If I ever do I'll let you know if some Mercs will add to the flavor.

Anyone that would like me to upgrade their AC4 may contact me at my email

I will explain exactly what is needed. It is fun amp and much more recording friendly and pedal friendly when modded.

Rat Valve Amps makes note of the fact that the quality of components chosen by Vox for this amp is extremely good. In fact the stock output transformer is said to be "superb", and this from a guy that has been building and modding amps for 35 years. I have the AC4 head and it's proven to be phenomenal value. Have had it for 1 year now, no problems, no hiss or hum, just great tone. Save your money and keep this amp stock. Save up for a Carr Raleigh if you want something special.

I think both are really nice sounding..On the rhythm work I like the mod better as it was much less harsh and better balanced but the original one's brightness I think sounded nice on lead. I like both..

I Love all my Amps, which are all completely stock! Some of them are Fenders,Marshalls from the 60ies,70ies,some are Modern Boutique Amps like Dr Z and some are Brand New Reissues like the Vox AC4!

A great example of how "better sounding" is in the ear of the beholder.

Dear Mercury Magnetics, stop "upgrading" amps. Thanks.

I was ready to send my AC4 to Fargen for a mod. I'm glad I watched this first. I like the stock amp much more. The mod sounds like it is a lot less bright and has dull highs. However, lows are improved by the mod. Not worth it to me. Thanks for posting. You have a cool style...

At first listen, the stock sounds better. But the modified is actually so much more useful, it seems. I mean, having a dynamic high end is nice. But it can be piercing and cause problems in your mix a lot.

Listened to reviews of Marshall class5,Blackstar HT5 and standerd Vox AC4 tonight and your modded Vox blows them away bro` ! An amp maker should offer your mod` as an optionall extra ! Well Done ! Pece Ye`All !!
