Compression FUN - Get your squeeze on!
Posted: Thu Mar 25, 2010 11:00 pmI have a neighbor down the street who is a fantastic slide player and has been supporting lots of cool artists since the late 60's, both live and in the studio, his discography includes, Bonnie Raitt, Linda Ronstadt, Little Feat, Crazy Horse (yes that Crazy Horse), Jerry Garcia, and the list goes on.
Anyhow I started working on his amps a couple years ago and last week he brought in a pretty cool and unique compressor for a re-cap. It's a CEi ACP-1 Compressor-Preamp. When I was done re-capping it I thought it sounded great. It was obviously never meant for guitar, today I found that Charles Caringella (CEi), published the project in Popular Electronics in February 1968 and called it COMPLY, with specific applications for tape recording and CB/Ham Radio use. I think with some minor tweaking this could really be a great alternative to the Dyna-Comp, it's got a lot of sqish on tap
The only differences in the unit I worked on and the schematic were.
- 100n cap at input before the pot (not present on publised schem)
- C2 = 100pf (270pf on published schem)
- diode on my unit was 1n60, NPN trannies were 2n3390 and PNP trannie was 2n1307
