Really pleased with my new Ceriatone 2204. It beats the pants of the other 2204 I owned (a '78 JMP50). One of the best differences is how quiet this amp is at full gain. The background noise is really low (even though I've got a PPIMV installed too - useless with this circuit, BTW). The moment I got it, I did a few little tweaks, as I like to tame the 2204's cutting treble and give it rather fuller mids and bass. Nothing tricky. I am really pleased with the result. Here's a clip I did through a Marshall 412 with greenbacks :- http://www.box.net/shared/static/78qv411onh.wav (wav file - really does sound better !) http://www.box.net/shared/static/ps76hcm82r.mp3 (mp3 - iffy sound quality, but quicker to download) The master was only on about 0.5, so hardly even on really. I can't wait to be able to open it up, and see what she's got !
