Introduction
For more than 50 years VOX AC30 is one of the most famous amplifier ever. Countless guitarist was using this amp for recording and gig including The Beatles, the edge (from U2), Jimmy Page (from led zeppelin), you name it.. AC30 is really famous because their top boost channel. It can produce sweet chimey clean to british crunch. To explain it, just listening to U2 songs. VOX actually make their famous AC30 model based on AC15 that first introduced at 1958 by JMI music. AC30 is a combo tube amplifier output rated is at 30 watt. So basically AC30 is a double powered AC15. More power wattage has more advantages for large auditorium, while lower wattage is great for small auditorium.
Better than before
Okay, enough about historic talk coz you may search about the legendary VOX AC30 article around the web. Recently in 2010, VOX announced their revised model for their AC15 called AC15C1. C means Custom, while 1 means it come with one speaker. The new model replace the old model named AC15CC1 wich means AC15 custom classic with one speakers. From now on, let call the old one cc1 and the new one c1 okay? The new model has a lot advantages compared to the old model.
1. CC1 does not have a tone cut circuit for power section while C1 have. The tone circuit works like tone knob on guitar.Crank it all the way, then it will cut highs a lot. Roll it back, you get more highs. It was a standard feature for AC30 not AC15, and this is very nice feature for C1 model. Many people complain about ice picky high sound from CC1 model, and it was cured in the new model and also with addition tone cut circuit it can be very versatile.
2. CC1 use a modern style power and standby switch, while C1 use a classic style switch. For me, I like vintage style switch more than modern style.

3. The reverb and tremolo also very good feature. Many people complain about CC1 weird reverb, now the C1 reverb totally usable.

4. C1 model also came with two channel. Top boost and normal while CC1 has only one top boost channel. By additional channel in the new model, it can add more versatility to the sound. The both channel are not foot switchable without A/B/Y box. With A/B/Y box, you can foot switch between channel and even combine the channel. Some people really love the channel combination.

5. The new model also come with celestion green back speaker with semi-closed back cabinet, while the CC1 come with custom VOX warfdale speaker with open back cabinet. This is also very welcome future.

Technical spesifications and construction

All the tubes are Chinese made tube. And it replaceable if you want using better tube one day.

Overall Construction:
It relatively small, but weigh about 22kg / 45lbs. Cannot be categorized as a light weight amp, but this is way lighter than AC30. This amp is made in china, but I think it IS reliable amp. We’ll gonna see what happen next ten years hehehe.

My thoughts
I played guitar about 10 years, and this is my 3rd amp. Before that I am a marshall fanboy, and I already try marshall amps including solid state, valvestate series, and JCM2000 DSL. Well I gonna say, this amp (AC15) very kick ass. The clean are very clean (and chimey ofcourse) and the overdrive are very smooth and not muddy. Compared to marshall, for me this amp is more verstile. Well sometimes, I really miss marshall crunch tone. I am a big fan of amp dynamic response, and this amp is will give you a very dynamic response. It’s really sensitive with your playing style, volume knob, and tone knob. This amp also really love overdrive pedals. My impression about the tone is: the highs not ear piercing, mid are organic, and low very clear. Master volume does have a huge impact to overall sound quality, but it will a be wise if you turn master volume down to low level when you use it late nite home practice before your neighbor will kill you. I give 9/10 soundwise.
Oh, last thing I almost forgot to say. This amp does not have fx loop, so my delay and chorus pedal will sound weird if I cranked the pre-amp volume. That is the only problem I had.
Okay thats my personal review. Hope you enjoy it.
