EliasMooseblaster Posted October 15, 2019 Posted October 15, 2019 I stumbled across this after somebody started a thread about AMT Electronics' preamp pedals over on the Effects board: https://amtelectronics.com/new/amt-12ax7ws/ If I've understood correctly, they seem to be pitching this "Warm Stone" device as a direct replacement for conventional vacuum tubes in valve amplifiers. I see they claim that people couldn't tell the difference in a blind audio test - well, that's marketing departments for you. Has anyone come across this kind of witchcraft before? Does it do what it claims? Is it the next logical step once I've finished replacing all the filament bulbs in my home with LEDs? Quote
MartinB Posted October 15, 2019 Posted October 15, 2019 They're a bit cagey about whether their new "Brick" pedals have these things pre-installed, which is naughty since they're advertising them as "tube guitar preamplifiers". I'm definitely not someone who believes that valves are magical and will never be bettered, but I'd still like to know exactly what I'm getting! Quote
EliasMooseblaster Posted October 16, 2019 Author Posted October 16, 2019 Yeah, I went back to the Brick listings after I saw this, and I noticed they offer a choice "at manufacturer's discretion" - so the default option is probably a Warm Stone substitute, but you can have a real 12AX7 if you ask. A bit cheeky, I agree! Quote
Bill Fitzmaurice Posted October 16, 2019 Posted October 16, 2019 Maybe they sound like valves, maybe not, but unless they come out with 6L6 or EL34 replacements they still won't duplicate the sound of an all valve amp. Quote
Twigman Posted October 16, 2019 Posted October 16, 2019 AT 39€ a pop I think I'll give that little experiment a miss Quote
Chienmortbb Posted October 17, 2019 Posted October 17, 2019 The only real valve/tube replacement is Korb’s Nutube. Quote
