Open Discussion / Cupcake compression
June 01, 2011, 07:06:42 PM
I finished a cupcake and it sounds as expected (very good, but too compressed for me).  I'd like to either adjust for less compression and/or blend the original signal with the compressed signal using set-and-forget internal trim pots or components in sockets or the unused opamp in the 4558.  The sustain trimmer does not change the compression much, just makes it sound better/worse.  Any suggestions?  Also working on a Ross/Keeley clone.  Maybe just stick with that circuit?
Thanks, Doug
Requests / Johnny Octave?
January 08, 2011, 12:24:08 PM
Looking to build a clean octave pedal ... similar to the ZVex Johnny Octave ... but switchable either one octave up or one octave down.  I prefer to buy a pcb, not etch my own, and I'm really slow and messy on perfboard.  Any suggestions?
General Questions / BAT41 source or substitute
January 06, 2011, 04:14:51 PM
Looking for a reasonable source for the BAT41 or a suitable sub from small bear.  Mouser wants $5 to ship a few diodes.  Looks like the fwd v-drop of only .45v is what makes the BAT41 unique.  Any suggestions?  Or shall I just suck-it-up and pay Mouser.
General Questions / Sqweeker Mods
January 04, 2011, 01:26:50 PM
Hi all, Just built a sqweeker and am looking for advice on changes.  It is a bit too fuzzy.  I'm looking to clean up the dry and octave as much as possible; more like a Johnny Octave.  It also has this weird volume gap in the mid-volume level of my playing.  It is either too quite, or jumps to full volume.  If I lighten my pick attack, it jumps too quiet ... almost like a gate.  I plan to better match the resistors/caps around the diodes and try different diodes.  Any other suggestions?

BTW, mine also picked up radio stations on the test board, but is nice and quiet in the 1590a.
