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.
Thanks!

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.

Thanks!
