Roland Dimension-D vs. Boss Dimension-C
I've been curious for a long time...how similar are these two effects? The Roland one is a rack unit, the Boss is a stompbox. Each is a subtle chorus effect, each has only 4 presets and no knobs, just a little row of buttons. I have the Dim-C, it's a great effect! But does anyone have experience with both? Just out of curiosity.

Inverseroom, apparently we're on all the same boards....
But yeah, they're pretty much the same thing except one is a balanced stereo rackmount and the other is a mono stompbox.

I have schematics for both.
DimC makes a stereo output out of a mono input and operates on a 9V battery.
DimD can process either stereo or mono input, makes stereo output, and operates on +/-15VDC.
DimC is inferior audiowise, it does not have the bandwidth of the DimD and has less than 1/4 of the components of the D. That is a compromise of stomp design, you have to
a) get the most out of fewer components because
b) a 9V battery has limited current supply therefore fewer parts equal longer battery life,
c) designing audio devices with a single power supply rail requires DC offset at the audio domain to prevent clipping of negative peaks and that means AC coupling at input and output, meaning limited bandwidth,
and finally d) opamps running at lower voltage supply differentials mean increased noise and distortion. But since stompboxes are targetted to guitar players, most of them won't notice this.
