This is a pretty interesting (to me) unit because I pretty much always have an overdrive pedal on, set to clean boost. So I'd probably use the Tweed modes. Anyway, has anyone tried one of these things? the only downfall is all the knobs and switches that need to mounted. A tad pricey too.
Well, you could replace your volume with a concentric pot for gain and volume. Then just set modboard to be on when you plug in the jack... and the only way to turn it off would be to unplug your output jack. This means there would be no bypass unless you put in a switch at some point.
The only problem with no bypass is if the battery goes dead... you get no sound.
