Ladies, Gentlemen, Pornstars:
Got to try the Alchemist for a few minutes last night. The shop only had a 1x12" combo; the head was dysfunctional (The rap on Line 6/Bogner production is that QC is not what it should be - is this a sign?)
I brought a 1969 Strat I had made that I think has graced this site once or twice. The hardtail sunburst, not the blue ice trem guitar. Tuned to Eb.
I also didn't get a chance to turn the amp up much, but what I heard was quite fat. A bit modern for my taste. None whatsoever of that bass kick I crave, but that may have been the lack of volume and the single V30 speaker. Surprisingly dark, considering the choice of (my not so favorite) speaker.
What I liked best was that the Alchemist offered a wide and seamless range of tones. The switches (bright, shift, etc.) seemed to affect the tone more than the eq, but that may have been again because I wasn't playing loud.
I deliberately didn't play with the reverb/DSP, as I wanted to hear the amp. If I liked the amp, any reverb would be icing on the cake.
Preliminary finding: definitely worth further investigation, especially a head and 2x12" cab, as it offers a G12M and a G12H, which is more what cats are after.
