Ok, so I have schematic being drawn up and I have a manufacturer for it so I just want to do some market research.
So here are the options for the pedal/s
The smallest box available [url="http://farm1.static.flickr.com/230/511937211_66b19c596d.jpg"]here[/url] in this size with no led or footswitch, won't take a battery will have input, output, power in and a knob to control the impedance, it will be this small and won't have a switch or an led as it will always be on and be the sort of thing that takes up little or no board space or fits under a pedaltrain type board.
Same box as above with an led and a footswitch so you can turn the impedance buffer off and make your fuzz sound gated and crap again again.
Single TB type loop in the standard MXR sized Hammond enclosure with led, to show when the loop is activated, footswitch to turn the loop on and therefore the buffer and you just have your fuzz inside the buffered loop. this case would be able to take a battery.
Personally I lean towards the first one, buffers don't really affect other effects so why not leave it on.
But yeah so I want to know who would be interested in buying one and what model they would want.
Else it will be another custom jobby for me and exactly what I want and no one else will be able to get one so please speak up if you are interested.
Cheers
