In every case, the amp had the output bias set to 'Hot' and the smoothing set to '44 uf Modern.' More info here for anyone that's not familiar with all the controls: This channel has a lot more treble and also more gain than the Normal channel. The amp has a 'Normal' channel which is based on the pre-top boost AC30s and is very low gain, and also a 'Top Boost' channel wich is built upon the more common Top Boost AC30 circuit.
This is a very bright amp, so please take this into consideration when reading my impressions of each of the tubes.
VOX AC30CC2 SOVTEC TUBES UPDATE
This amp is the second update to the new CC series, so it's got the non-soldered speaker cables, fixed tremolo and effects loop, and is generally more reliable. I'm running a stock late 2007 Vox AC30CC2, which has the Wharfedale speakers, both of which have been fully broken in. Here's a list of the tubes I'll be talking about:įirst things first - some info on how I went about testing the tubes: I'm passing on my observations to you so you can get the same results minus the hearing damage
I've just spent about the last 8 hours drinking coffee, swapping tubes, playing guitar, and generally trying to deafen myself with a range of tones from ear-meltingly awesome to teeth-grindingly abysmal. I mentioned in another thread a few days ago that I was in the process of comparing a range of different new production and NOS 12ax7s in my AC30CC2.
