Ceriatone DC30

Description

Here is a set of profiles of my Ceriatone DC30, a clone of the mighty 30 watt Matchless DC30. The amp's circuit is a 1:1 copy of the original, but the Ceriatone is built on turretboard, not true point to point, and the transformers are slightly different too. There some differences in the speakers, but that does not matter here, as there are no full rig captures, only direct amp captures. For those that don't know this amp: There are two channels, both slightly modified after vintage Vox amps. Channel 1 is similar to the AC30 top boost, and use two 12AX7s in the preamp, while channel 2 is similar to the vintage AC15, based on one EF86 tube. Even if they have the same heritage, the channels sound quite different: the 12AX7 side is the more linear of them, can be slightly scooped if you set it so, and stays cleaner a lot further up on the dial. On the EF86 side, the word clean is a relative term. This channel breaks up very early on the dial, and there is no chance that this channel will sound scooped. It is more compressed, and can sound really FAT, and definately more complex (and looking at the waveforms, it clips VERY assymetrical). It has just a tone knob with 6 fixed position, starting out bright, and for every click, it just gets fatter. But even if the two channels are different, they both run through a 4 x EL84 power amp, again very similar to the original VOX AC30 design, and this makes for two channels that fit well together in the same amp. They are great jumpered or in parallell too. The amp can run at half power, through only two of the power tubes. Both channels share the typical VOX cut knob, and at last a bypassable master volume. The half power and the master is extremely useful when playing the amp through it's speakers, as it is extremely loud for it's 30 watt rating. In most live/rehearsal situations, I have played this amp only at half power, and still I had to use the master. Now onto these captures: Tecnical stuff: captured throug a Palmer Trave reamp box, dBu level is 12,1. After the amp is a Two-Notes Torpedo Captor 8 loadbox (thus the amp ran at 8 ohms). All captures were normalised to -3 dB peak level before training, so normalisation in the plugin should not be nescessary. Trained at 600 epochs in standard mode. ESR is in the range of 0,008 for the cleanest profiles of ch1, up to 0,013 for the gainiest captures on ch2 (because ch2 is a LOT more complex...) and the dimed ones. I tested training some ch2 captures with more epochs, but saw no significant change.) I have not gone to any extremes in the tone settings – I wanted to find variations that would make this set fit for a lot of different guitars, from bright, low output teles to high output, fat LPs and all in between. Both channels are very sensitive to the guitars output volume too, so play around with the input level if you don't hit the sweet spot like it is. I used two different tone settings for each channel, each of these with two different cut settings, and then captured with 5 different volume settings. The volume is given in percent, tone settings are given in abbreviations, to not fill the filenames with a lot of numbers: Channel 1: NTR means neutral, where both bass and treble is set to 3, for a tone that is less scooped. SCP means scooped - wich is not as scooped as a BF Fender – anyway: bass at 4, treble at 6. Channel 2: BRT means bright, and I went for the second brightest setting on the dial. FAT means, well, fat... it's the second darkest on the dial. So that is a main bulk of 40 profiles, but there is more: There are 4 profiles of the channels jumpered, and there is one of each channel with volume dimed all the way up. Then DC30 enthusiast Jon Arnold got two captures of his suggested setting, and at last but not least, there are two profiles especially for Bob Guido. Oh, by the way: Most of these are captured on full power, with master bypassed, to get all that glorious power amp goodness from the EL84 power section. But to have a more controllable preamp gain range, I captured through the low inputs on both channels. There are some exceptions: Bob Guido's profiles and the dimed profiles are captured with master at 7. And Jon Arnold profiles are one captured through input one, and one through input two. Both dimed profiles captured through input one. Jumpered profiles are into input 1 on channel 1, jumpered to input 2 on channel 2. I have to thank two people for helping me out: Bob Guido for testing, listening and giving very important feedback. Jesco White for patiently guiding me through the technical side of capturing and training. Thank you so much guys, you both made this pack better!
