Super Skwisher - Ross /Dynacomp/Boutique Compressor

From the vendor

NOTE: the build doc still shows the pre-LM13700 version of the PCB. It'll be updated at some point. The BOM is identical. Follow that, not the pic. Sorted.

All new, all singing and dancing version of the Skwisher with multiple options.

**Now configured to use either the original CA3080 IC or the more readily available, non-counterfeit LM13700. Both sound identical.**

The mighty squashing goodness of the Ross Compressor. The sustain just goes on and on.

Build the stock two knob version or add an optional board-mounted toggle swtich for the Mark Hammer variable recovery mod - well worth it.

If you want even more tweakability you can build the 4-knob version, adding pots for Clip and Attack as well as the stock Level and Sustain controls.

Compression isn't top of the list at FuzzDog HQ, but after wiring this up and plucking a few clean notes the room was filled with chiming tone akin to Mark Hollis' later Talk Talk sound. Outstanding!

Note: the 4-knob version requires 150KB pots. We ain't got any. Kit will be supplied with 250KB for these controls, which gives you more adjustment than is entirely necessary, but that's better than not enough. You have the option to put resistors in parallel with the pots to get them to 150K, but that changes the control taper. It's up to you which way to go. If we can source vertical-mount 150KB in future we sure will.

The kit is supplied with vertical-mount pots which have round shafts, so you'll need set-screw fitting knobs.

If you want the PCB without parts there's a link for that at the bottom of the page.

Partial kit: PCB, all board-mounted components, pots.

Full kit: As above, plus footswitch and appropriate daughterboard/components for your selected bypass type (see Downloads section for details of those), jack sockets, DC socket, battery snap, hook-up wire, LED.

Enclosure (pre-drilled) is available as an option with full kits, and will not take a battery. Knobs are not included.
