Hi Guys - I just picked up the amp reviewed in the article below in a trade. The only changes made to it since the review is that the speaker has had a hemp re-cone on the Celestion Blue. It's really a super inspiring beast to play, and I've been very happy with so far, I feel it is upping my game due to the touch responsive qualities and the fact that you play it as well as your guitar, putting you in an 'inspiration loop'...it gives back everything you put into it. Massive sustain, uber thick cleans, plenty of gain available if you go there, very transparent, bloomy and chime-y. Reminds me of a Trainwreck Rocket style amp I once played. https://web.archive.org/web/20091222041956/http://www.jcacircuits.com/ToneQuest.pdf Why are these so under the radar? What happened to the builder? Any other owners out there? I found a Facebook page with 4 members, and that's about it for current active users. If you have knowledge, or own or have owned one, please share your stories! Thanks, happy playing.
