...... are really a "thing". Never put a ton of thought to it, have one chorus pedal with it, one reverb without. Did some plugging and unplugging to test out the A/B aspect of it and was pretty shocked with the results. The reverb pedal is a boss digital reverb and it's been my secret sauce to getting a great jazz lead tone, shorten the time, thicken the effect level and instant Pat Metheny tone, .... done. (or so I thought) When not engaged it really shaped my tone, and not in a good way. I would make adjustments to compensate, but after taking it out of the effects loop not only the tone, but the articulation improved vastly. For years I used my Rectoverb sans-pedals and was so happy with the directness of the whole equation, the tone, controllability, and articulation. Since I sold it I've been jumping around ampwise and using pedals more, this "true bypass" thing is more than just a selling pitch, I found it to be really real. .... now I gotta go shopping for a reverb pedal.
